Heirloom Tomatoes 2021

I grow a lot of tomatoes each year, I really love tomato season.  Some varieties are far better than others.  

My kids help me grow the tomatoes, collect the fruit, eat some of the tomatoes, bag some flowers and save some seed for the future.  

I don't have enough space/water/time to grow every tomato I have every year.  I have two tomato varieties that I do grow every year because they taste incredible (Japanese Black Trifele, and Verde Claro), and the rest I grow on a rotation to refresh the seed every 3 years.  

On second thoughts, I also grow micro tomatoes every year, but they are more for novelty and for breeding rather than for feeding my family, plus they take next to no space, so I don't tend to mention them.

Various tomatoes I grew

Some of the tomatoes I grow are very old heirloom varieties, others are more modern, while others I am breeding myself.  This year I grew 14 or 15 varieties of regular tomatoes (dwarf, or determinate, or indeterminate), and a small handful of micro dwarf varieties.  The plants range from a few cm tall to about 2 metres tall depending on the variety.

I also grew some wild relatives of tomatoes and some wild x domestic cross tomatoes.  I really need to take some photos of them and save some seed before winter comes. 

I thought I would show off some of my tomatoes below.

Tomatoes: Tommy Toe, Unnamed, Reisetomate, Igloo, Japanese Black Trifele, Verde Claro, Snow White, and Black cherry

My absolute favourite tasting tomato is called 'Verde Claro'.  It is a green when ripe cherry tomato that tastes incredible.  They look similar in size/shape to a grape.  Whenever people try these they love them.  

Every time I let people try these along with any other variety they always say that verde claro is the best tomato they have ever eaten.  They aren't the perfect tomato, but their taste is absolutely divine.  There is good reason I grow them every year!

Verde Claro and a bunch of grapes

I love the red tomato called reisetomate.  The flowers and fruits are fasciated, the fruits are red and lobed and can be pulled apart into segments.  

Reisetomate tomatoes are very sour, a little salt brings a true depth of flavour that I really enjoy.  Each and every tomato has a unique shape.  

Reisetomate tomatoes

I have been working on developing an improved black tomato for a while now.  The unripe fruit is purple and beautiful, it almost looks like an egg plant.  The ripe tomatoes have greenish yellow under the black, and the flesh colour is green.  

The black comes from high levels of antioxidants, and only appears where the sun hits the fruit.  They are roughly ping pong ball sized fruits and possibly my second favourite in taste after verde claro.  The fruit are a bit too small, but still large enough to slice for sandwiches.

I need to name these and start distributing the seeds as they are an incredible tomato variety.  I would hate to lose them if anything were to happen to my stock.

One of the varieties that I am breeding

This colour in tomatoes was unimaginable a few years ago

Another I grew this year was a variegated tomato.  I grew them to do some breeding and a few other genetics experiments, but after talking to some other growers I don't think anyone else in the country has variegated tomatoes so I should probably try to distribute the seeds so this allele is not lost.  Like many variegated plants, these aren't quite as vigorous as all green plants.

These are truly beautiful variegated tomato plants.  The leaves and stems get variegation of green, yellow, white, and pink.  The fruit is mostly red and round (although some fruits are slightly variegated) and tastes nice and surprisingly sweet.  

They could happily live in a flower garden and are a stunning showpiece of a plant.

Variegated tomato foliage

Micro dwarf tomatoes are heaps of fun.  These Micro Tom plants are thriving yet not reaching 5cm tall!  I am doing some breeding with them and hope to have something incredible to show for my efforts next year or the year after.  

You won't feed your family with micro tomatoes, but they can grow in a cup of soil on a window sill.  Traditionally they can taste a little insipid so they need some work in improving their taste, which is why I am breeding new micro tomatoes.  Some of my newer lines taste better than others.




I grow everything organically and sometimes sell some tomato seeds through my for sale page.  If you see something you love and I don't sell them let me know because I may be able to get you in touch with someone who does.

Skirret in Australia

Skirret (Sium Sisarum) is the ultimate perennial vegetable.  As far as I am concerned skirret is the perfect vegetable for organic gardeners, permaculture gardeners, people who are into increasing self-sufficiency, people who are increasing their food security, and people with fussy children.   That’s right, even fussy kids will eat skirret.

Skirret has a long history as a vegetable, it has been blessed with the highest recommendation and cursed with the lowest popularity of any of the root crops.  It grows wild across Asia, and has been well established across Europe.  Skirret may have made its first documented appearance in a 1322 list of seeds maintained by the gardener for the Archbishop of Canterbury, Lambeth Palace, which included a penny's worth of skirret in a 1321 to 1322 inventory.  We don't know how long it was used as a vegetable prior to this, it is believed that skirret grew along damp riversides and ditches and was easily harvested for free, so didn't need to be bought and sold.  It is likely that skirret was grown and eaten long before this but simply not recorded.

People keep telling me that there is no skirret in Australia, but I grow skirret, I sell skirret, and eat skirret.  I have given skirret to some people who now also sell it.  So skirret is slowly becoming less rare in Australia.  Hopefully one day I will see skirret for sale at a farmer's market.

I adore skirret, I have grown it for a number of years now, have written a few posts on it to try and show other people how to grow it.  Skirret is the most delicious roast vegetable ever.  I have never eaten anything that even comes close to how great skirret tastes.  I like the taste normally, but frosts make it far sweeter.  I want to encourage more people to grow this remarkable vegetable.

Benefit Cost analysis of growing vegetables in the backyard

People often tell me that growing vegetables costs too much, or that they are cheaper to buy from the shops, my reply to them is "you are doing it wrong".

Growing vegetables will save you money.  If you are spending more than you save you are doing something wrong.  Grow some food, it will save you money. 

If you have a back yard you should grow some vegetables.  I grow and eat plenty of things that I could never afford to buy.  It is simple and it will save you some money.  I will tell you how I used to grow vegetables cheaply in suburbia with limited space and give you an idea of how much money it saved us.
Heirloom tomatoes - one day's harvest

Growing Vegetables in the backyard to save money

When we first bought a house with a small yard I put in a small vegetable garden, I sat and thought before each purchase as I wanted to save money.  I tried to make sure that everything I bought would return the investment in 3 or less years, if anything would not return that investment I asked myself if I really wanted it.  Sometimes the answer was still yes.  Why did I choose 3 years, I can't remember, it is just the rule that I go by when making purchases.

When I was about to start that garden I looked for something to make it from for free.  We had a sandpit in the lawn left behind by the previous owner, I dug out the sleepers and used them as the vegetable garden edging.  I dug over a section of lawn that was out of the way, put in the sleepers as edging, and included some of the old sandpit sand to improve the drainage.  It cost me time which I otherwise would have spent in front of the television, and I bought a cheap spade and wheelbarrow (which I needed to buy for other projects), but other than that it was free up to this point.

I needed to buy some vegetable seeds or seedlings to plant, this was my first real cost.  I decided seeds were cheaper than seedlings and offer the best return on my investment.  A packet of tomato seedlings costs about the same as a single tomato plant and can be used to grow many tomato plants over several years.  I also decided that any seeds I bought must be of things that I could grow out and save seed from each year or of something perennial that would not need replacing each year.  This makes seed buying a once off expenditure so even if they never break even they will still be providing me food for years to come.  At that stage I had no intention of ever selling seeds or breeding my own superior varieties, I was only planning on saving a little money by growing vegetables in my spare time.  Saving seeds lowers costs dramatically, you should save some seeds for yourself.

I normally don't include costs and things in blog posts as they vary from place to place, but to demonstrate how growing vegetables in the backyard is far cheaper than buying them from a shop I am going to include some dollar amounts here.  I am also going to try and be realistic and include things where you may lose money.
Yellow pear tomato, seeds are cheap and yields are high

Benefit/Cost comparisons of growing vegetables in the backyard versus buying vegetables

I payed $3 for a packet of tomato seeds so I wanted to get at least $3 of tomatoes in less than 3 years.  That was my goal, everything had to break even within 3 years.  I can't remember how much each plant produced, or how many plants I grew that first year, but all together they returned about 12 kg of fresh tomatoes.  According to this site one kilogram of tomatoes costs about $5.  Not surprisingly one single tomato plant returned a lot more than $3 worth of tomatoes in a single season.  I am not talking organic gourmet tomato prices (even though I grow everything organically and I probably have what is considered gourmet varieties), I always calculate using the cheapest vegetable I can find.  I then saved seeds from those tomatoes and actually still have that variety today.  That was 12kg of tomatoes the first year for $3.  Already, with that one purchase of tomato seeds, I had lowered the costs of my fruit/vegetables a tiny bit.  I was already ahead.  We were already saving money by growing vegetables.

If you are not breaking even in under 3 years you are doing something wrong, perhaps you are growing the wrong variety or perhaps tomatoes or whatever it is are not suited to your climate and you should grow something else.

When I payed $7.50 for a kilogram of seed potato that first year I wanted to get at least $7.50 worth of potatoes in under 3 years.  The first year that 1kg of seed potatoes returned 20kg of good sized potatoes plus a few kg of smaller ones that I saved to plant the following year, the second year they only grew 15kg of large potatoes plus some to save, the third year they yield 8kg.  That's right, I keep pointlessly accurate records of things like this.  So for an initial $7 investment I got 43kg of potatoes over 3 years, not too bad.  Again, if you are not at least breaking even you are doing something wrong.  The average price of potatoes is around $3.78 per kg, so around 2kg breaks even.  The $7.50 for seed potatoes was well worth the investment especially considering the 20kg return the first year.  It is not difficult to save money by growing your own food in a small backyard garden.

That first year we spent $10.50 on tomato seeds and seed potatoes and ate around  $135.60 worth of fresh produce.  It is not difficult to see how much money can be saved by growing a few vegetables at home.
Perennial leeks, plant once harvest forever
We grew a few other things that first year, almost all of them returned far more than I payed for them.  Beans and snow peas grew tremendously well that year and I saved seed to grow in following years.  As well as providing a delicious crop, being legumes they also sequestered nitrogen from the air and made the soil more fertile and productive which was an added bonus.

Some seeds I bought did not provide great yields in that tiny vegetable garden.  It is important to know that this is going to happen too.

I bought multi coloured carrot seed, they grew well but when carrots cost $0.65 per kg I did not get $3 worth of carrots out of them that first year due to lack of space.  I probably got about 50 cents worth of carrots.  I saved some of their seed and planted the following years, to be honest I don't think I ever got $3 worth of carrots from them and should have probably stopped growing them.  You need to grow a lot to break even when they cost so little from the shops.  Space was the limiting factor there.  I was not saving money by growing carrots so I stopped growing them and used the garden space for more productive and worthwhile crops.

I bought an apple tree in our second year to plant by the fence, after counting and weighing the apples that we ate from that tree (I can't help but to weigh, measure and record certain things) and factoring in the cost of apples of the same variety from the shops I found that I broke even part way through the second year.  There is no point using the cost of organic apples as I would not buy them, I would buy the cheaper ones.  

I was also given some strawberry plants which performed wonderfully, it is difficult to work out how much they saved us as I would never buy strawberries because they are too expensive and do not taste very good.  These plants did replace other "afternoon tea" and "dessert" type foods so actually did save us a decent amount of money.  Considering that they cost me nothing to begin with I was more than pleased.
Herbs are worth growing, but they probably don't save you money
I also bought some herbs, this is where costing got even trickier.  Normally I would never buy fresh herbs as they are too expensive, so no matter how productive the plants were they would never truly break even.  This is ok when you factor it in with other things that actually did lower costs.  It is good to know that there will be things that are worth growing that will never break even, it is wise to make informed decisions about such things.  Lets be honest here, growing ornamental flowers never breaks even yet they are a multi-million dollar industry in Australia.  I think growing a few herbs is a great idea as they taste great, it should be a once off purchase as many herbs are perennial and it is simple to save seed from most annual herbs.

Then I bought some things that I had never seen in the shops, things like yacon.  I figured this was dead money as it was not replacing anything I would (or even could) buy.  I was willing to proceed as everything else had grown so well and lowered costs.  The trick here is not to ensure that each individual plant breaks even, but to make sure if something will lose money that you are aware of it before hand and have accounted for it somewhere else.  

The yacon grew amazingly well, the kids and I love to eat it.  It had saved us no money as it was not even replacing some other fruit or vegetable.  Yacon roots secrete sugars into the soil and attract and feed beneficial soil life such as earth worms.  Everything that grows near yacon seems to be larger and healthier, so it probably does save us money in some way that is too difficult to calculate.  Yacon is a perennial vegetable and I still have that same yacon growing today, it is one of my all time favourite vegetables.  I believe it was money well spent.


Production costs of growing vegetables in a small suburban backyard

People often complain about all the 'hidden' costs which I have conveniently ignored so far, what about fertilisers, pesticides, herbicides, water and most importantly time?  Again I say if you are not saving money by growing vegetables then you are doing it wrong.  Lets look at these hidden costs.

Fertiliser
People often complain about the cost of fertilisers when growing their own food, I have never used them.  You don't need to use them in a backyard, it is cheaper not to.

When we lived in town I would compost the lawn clippings as well as tea bags, egg shells and whatever vegetable scraps we had and use that as fertiliser.  It was virtually free as we were using an otherwise wasted resource and the vegetables grew tremendously well with that as the only fertiliser. The soil got richer and more fertile each year, this cost us nothing.

After a while we got chickens and also used their manure and bedding as fertiliser.  Someone gave us their old guinea pig, this little guy worked tirelessly eating weeds/grass and turning that into manure.  He lived a long life with us, reaching a ripe old age of about 7 eating nothing but grass and weeds and producing high quality fertiliser for us.  I miss him, he was a hard worker and a placid friend for my children.

There is no need to spend money on fertiliser as you will have something around that you can use for free.  I can understand large acreage buying fertilisers, but if you are spending money on fertiliser in town you are doing it wrong.
Chickens, a great source of manure (don't worry they did not live like this for more than a few minutes, we were only carrying them from the incubator to the brooder and this tiny box was the safest and easiest way)
Pesticides
People often complain about pesticide costs, again I have never used them.  If a plant gets hammered by insects then perhaps I should grow something else.  There is no point beating a dead horse, sometimes it is wiser to cut your losses and grow something else. 

Some pests can be beaten using other means, others sadly can not.  Cabbage white butterflies for example do not like to like to lay eggs where there are a lot of other white butterflies.  I tie some string running along the length of the bed next to the brassicas.  I then cut white plastic bags into small rectangles and tie them in their middle along the string.  The end result looks like a heap of butterflies fluttering along the crop in the wind.  Don't be fooled,  this does not eliminate the pests, but it does reduce them to a sensible number.  We went from several dozen caterpillars per leaf of every plant, which I was removing each day, to only 1 or 2 per entire row of plants.  This cost me a little time, an old plastic bag and a length of old string that I found in the garage. 

I keep slugs and snails away from seedlings by surrounding them with crushed egg shells.  Apparently the slugs/snails find them too sharp and do not go over them.  This has to be reapplied every now and again as birds or something steal the pieces of shell.  Egg shell is virtually free, my chickens and ducks lay eggs which we eat or hatch and I use the shells either in compost or to protect seedlings.
Crushed egg shells protect seedlings from slugs and snails

Herbicides
People ask me "what about weeds and weed control?".  In a back yard you should not have weed trouble that you can not dig out easily enough.  Large scale broad acre farms may be different, but in a back yard if you can not dig out a weed something has gone wrong.

If you have chickens or guinea pigs they can be put on a vegetable plot between crops to eat out weeds and fertilise the soil for you.  Chickens can be very destructive in the vegetable garden so I would only use them between crops and I would be careful they do not scratch all the soil out of your garden.

I don't see the point of using a herbicide in a small backyard vegetable garden.  If you do not have chickens or guinea pigs then pull out the weeds yourself, don't spray them.  If you can not pull out the weeds yourself due to ill health or something consider mulching heavily with newspaper or something.  People will give you piles of newspaper for free if you ask.

Water 
People often drone on and on about how much they will spend in water if they grow vegetables, in a small backyard this is not the case.  When we lived in town water cost $0.55 per kiloliter, I don't know how many thousand liters I would have used watering my tiny patch but all up it would have added up to maybe a few dollars each year.

The cost of water is undoubtedly a lot higher these days and would certainly vary from town to town, even so you would probably be looking at the cost over an entire year in single digits.  This is not a large cost and can easily be factored in to a productive vegetable garden.  There is certainly no point complaining about such a small cost each year when the financial benefits are so great.

Time
I can not put a dollar amount on your time, I also can't tell you how long you will spend gardening each week or total over a year.  This will depend on how much time you are willing to spend out there.

People often talk about how gardening is great exercise and excellent for good health.  Others tell me that they find gardening therapeutic.  Some people claim that the clean, organic, nutrient dense food they produce will save them medical costs, doctor visits and give them greater quality of life when they are older and less sick.  I don't know about this so can not comment.

I can't tell you the benefit/cost ratio regarding time in growing your own food in the backyard.  I don't know anything about that, but I do often think perhaps my time is better spent growing my own food rather than working so that I can pay someone else to grow it for me.  When we lived in town the time I spent in the garden was just time I otherwise would have spent in front of the TV.

I can grow a lot of things that I can not buy in the shops, and I can grow other things that are best fresh.  Some things such as sweet corn only taste their best when eaten within 15 minutes of being picked.  After that the sugars convert to starch and you lose a great deal of quality.  The time it takes to drive home with your 'fresh' corn from the shops is enough to stop it tasting its best.  I find that the small amount of time required to grow corn is more than worth it when it tastes so good.
Sorrel, you don't find this at the shops
Yacon, more than worth a little time to grow this at home

How much food can you produce in an average backyard?

Back in the old days most people grew most of what they ate, but back then life was easier and the world was a vastly different place.  House blocks were generally a lot larger and people had a great deal more spare time, it was quite rare for both husband and wife to have payed employment outside of the house.  Producing meat in your backyard was seen as pretty normal back then, today if you even consider butchering a chicken you would be frowned upon.  Back then people rarely bought much food, unfortunately times have changed.

If you wanted to you could probably produce all of your fruit and vegetables in your yard, but few of us have the time, the space or the inclination to do that.  Your yard would no longer be useful for anything other than producing food.  You are better off just growing some things that you like, still having a pretty normal looking yard that is still functional, and saving a heap of money along the way.  A 1m by 4m plot along the fence can be tremendously productive.
When we were in town we had two vegetable plots which were just under 2m x 2m, about 7.5 square meters together.  That small amount of land produced about 10% of our vegetables.  For 5 weeks each year we did not buy vegetables at all, then we got a few handfuls of vegetables throughout the rest of the year.  You can see how such a small amount of land can save you rather a lot of money.

I personally think that if you are not saving money by growing food then you are doing it wrong!  If you have tried and things are not going well talk to someone who may be able to help.  Just like the carrot example above you may need to change your plant choices.


Where to get heirloom vegetable seeds and perennial vegetables

There are many places that sell seeds and perennial vegetables.  Whenever buying please look at things that will either be perennial and grow for multiple years, or things that you may be able to save seeds from.  By doing this you will lower your costs as they will be a once off purchase.  Some things will be too difficult or time consuming to save seeds, that is ok too as long as you are aware of it and are saving seeds from other things.  Try to pick varieties that are different from what you can buy, many varieties that are available in shops are excellent for large scale farming and distributing over large distances but are not great for home gardens.  The aims of a home vegetable garden are different to that of a broad acre monoculture.

I sell some perennial vegetables and heirloom vegetable seeds through my for sale page and can post at cost to most of mainland Australia (not Tasmania or WA).  There are many other good small home seed sellers, as well as some larger ones that are good.  If you deal with the smaller family run seed sellers they are more likely to offer advice if something goes wrong as well as give you fresher seeds.  One of the largest and most well known heirloom seed sellers in Australia is dreadful, and ebay is very hit and miss, so do some research prior to buying anything.

You have little to lose and a lot to gain, grow some vegetables and save some money.

Snow White heirloom tomatoes


This year I am growing a bunch of different varieties of mostly heirloom tomatoes, some are incredibly difficult to find while others are far more common.  I will try to write a post comparing them all later in the season once they have all ripened or decided not to ever ripen.  For now I want to tell you about one of the best tasting cherry tomatoes I am growing which is called Snow White.

Cherry tomatoes are good, but many lack any real taste, they are often good for kids who like sweet things.  White tomatoes are good, but many tend to be a little insipid, that being said there are some amazing white tomatoes around.

I had heard that Snow White was one of the best tasting tomatoes ever bred and one of the best cherry tomatoes around, this had me intrigued.  I have also heard from others that it is nothing special and I would be better off growing other varieties.  A very generous grower sent me some seeds last year, how could I resist growing this and seeing for myself.
Snow White cherry tomatoes

The plant grew well in my garden while a few other varieties did not even survive, it flowered early and was one of the first tomatoes to ripen in my garden.  It seems to have a lot of flowers and unripe fruit on the plants at all times, being an indeterminate variety it should continue to fruit right up until frosts. 

The plants themselves are nothing remarkable, they grow about 6 feet tall here like many other varieties but I assume that they could grow a lot larger.  They have regular leaf and everything looks normal enough.  It would be nice if they were a dwarf plant or if they had potato leaf or something, but in the end none of that really matters.  The plants grow well under adverse conditions, provide large yields, but it is the taste that truly matters.

The first tomatoes I picked may not have been properly ripe, the seeds in them were not properly formed so it may not have been pollinated properly, or perhaps they get better as the season progresses, all I know for sure is that the first few were not indicative of this variety.  When I tasted them they were ok, nothing special, it is probably fair to say that the taste was a bit confused.  Considering that they were bred by Joe Bratka who is an excellent tomato breeder that has been described by those who know him as 'confused' or 'eccentric' I was not overly surprised.  The flesh was sweet and tasted a bit fruity, almost like a bland peach.  The seed part tasted like a regular cherry tomato, good but not great.  Overall it was good but nothing special, if the rest of the tomatoes tasted like this I may not want to grow this variety again.  The tomatoes ripen to a very pale yellow if they are in the sun or white if they do not get any sun on the fruit. 
Snow White tomatoes - yellow in the sunlight
Visually they looked good enough, they produced a lot of tomatoes, but due to the fact that there are thousands of varieties of tomato available in Australia I do not want to waste time or space if the taste does not blow me away.  I would rather keep trying to find something amazing. 

Then there was a week with no new ripe tomatoes, I was ok with that as they were not that great and the weather was odd.

Then the plant started to ripen again so I ate another tomato.  WOW.  They really blew me away.

Perhaps the first fruit were not great but since then they have been fantastic.  The tomatoes look much the same as the first ones, perhaps slightly larger, but the taste is amazing.  The flesh part tasted like delicious fruit, perhaps a peach or sweet ground cherry or something similar to that.  If I was to remove the seeds and blind test people I doubt that they would even recognise this as a tomato.  The seed part tasted like a good cherry tomato, a little acid but not too much.  The two parts together compliment each other well.  I love this tomato, I want more of them, I walk past the plant a few times each day in the hope that another one has ripened. 
Snow White hidden in the back of this part of the garden
The kids love this tomato, in my mind this is one of the best sweet tomatoes that I have eaten.  They are low acid so good for people who normally can not eat tomato.  I probably wouldn't use it to make paste or sauce or for cooking (although many people claim they are great for this) but happily eat them fresh or in salads.  They are remarkable.

I would almost go as far as to say that they are unique, but they are not.  Apparently the man who bred these also bred a few others which were much the same or exactly the same or just renamed this variety.  It doesn't matter too much, what does matter is that these are amazing and I plan to grow them again and hopefully grow a few more plants so I get more of them. 


Why are these tomatoes rare?

I have often wondered why this kind of thing is not more common, if they are so great (and these tomatoes do taste great) why are they not available at the supermarkets.  People often talk about home tomatoes being better because they are picked perfectly ripe instead of mostly green, or that they are fresh, or that they are too soft to be transported, and a few other things like this.

I am sure this is part of the answer, but I think one of the biggest problems is marketing.  People think of tomatoes as red, they are wary of any other colour.  Bright yellow tomatoes have started to become better known and appreciated in salads for their attractive colour.  Some of the brown/black ones have started to come in, but they have backing from a multinational company who holds a lot of power.

These are 'white' tomatoes, they mostly ripen a pale yellow.  Many people think pale colour means tasteless or not fully ripe.  The difference between 'white' tomatoes and yellow tomatoes is that the white ones have translucent skin.

Some people have asked me if yellow tomatoes taste the same as 'normal' tomatoes.  I don't know how to answer them.  Where do I even begin?

Unfortunately this means that the average person will never try these amazing little tomatoes unless they grow them at home as they will not be seen in supermarkets anytime soon.  Some of the best tasting varieties of tomatoes ripen green, many people will not even try them, that is their loss.


Where to get Snow White tomatoes

Seeds of snow white tomatoes are reasonably simple to find in Australia.  Snow white tomato seed seems to be carried by a few different sellers as well as ebay.  I have saved seed from my plants and will most likely sell some on my for sale page with other heirloom vegetables and perennial vegetables.

Immali Corn - Coloured Sweet Corn in Australia


I started messing around with corn breeding a few years ago. Corn genetics is messy, the more I learn the more I find that I don't know.  Genetics was so much easier when we knew nothing!

Many varieties of corn suffer from varying amounts of inbreeding depression, to save seed it is best to grow at least 200 plants and save seed from the best 50 to 100.  Some varieties of landrace corn have little to no inbreeding depression, but the down side is that they can be rather variable.  Using landraces as breeding stock means that genetic bottlenecks are not as tight and small populations can be slightly more forgiving.

Corn will happily cross pollinate with other types of corn that are within a few hundred metres up to a few kilometers of each other.  This makes saving corn seed difficult unless you live on acreage and have no one growing corn near you.

As I currently live on acreage and have no one growing corn close to me I save seed from a few different types of corn.  If I get the timing right, and am vigilant with selecting seed and rogueing out off types I could probably grow half a dozen types of corn each year without too much trouble.

I grow some interesting coloured corn, most of which is popcorn or dry corn as there are very few coloured sweet corn varieties available in Australia.  I once looked online at the amazing coloured sweet corn that is available overseas and asked myself: "self, why doesn't someone in Australia breed a decent coloured sweet corn?"  I looked around for someone who was developing a decent coloured sweetcorn in Australia, I could not find them.  I did find some people who are maintaining a few coloured sweet corns and a few who are developing the most wonderful yellow or white sweet corn, but none of this is what I was after.

So I decided to try to breed one myself.
Coloured Sweet Corn
Immali Corn 2015
I have some access to different coloured field corn and some different varieties of sweet corn that the average grower would not have seen.  I researched the varieties that I have access to in order to determine the best parental stock for my new variety of corn.  I got a landrace coloured sweetcorn, which tasted ok and has a lot of genetic variation.  This was one of the parents of Immali corn.  Every generation since then has been remarkably better tasting.

Some "Immali corn" seedlings
I planted some of the coloured seeds and saved quite a lot.  The results were good, but being so early it is clearly not stable and had a way to go.  A little back crossing would help to lock in the desired colours and also maintain a high level of genetic variation.

The early cobs lacked much colour, they tasted better than store bought corn but not as great as I had hoped.  Adding colour is not all that difficult, stabilising that colour is a bit more difficult, but I can do it.
Early Immali corn (ignore the yellow) - needs more colour
Tastes great, looks ok I guess, still a way to go

The later cobs look far better and taste far better too.  It is too bad I only get one crop of corn per year so progress is painfully slow.
Look how far it has come
Some fine looking "Immali corn" cobs
Still not there but look how far it had come

They still have a way to go, it is not yet stable and I do not want to distribute this seed until it is a bit more stable.  The colour will always vary a bit, but that is kind of the point.

The taste is a bit up and down right now, some cobs taste good while others taste simply amazing, all of them taste at least as good as store bought sweet corn.  This is mainly due to timing, if picked just right they blow me away, if picked too early or late they are not as good.  I would like to work out how to fix this, the genetics behind this are a bit beyond me at the moment as I do not have access to a good corn genetics book.  By only saving seed from the best tasting plants all of the Immali Corn should taste amazing by the time the colours are locked in properly.

Immali Corn
I worked hard to get here, we ate this cob and the colours remained unchanged through cooking

Once the strain starts to look more consistently like the cob above and is a bit more stable I hope to distribute seeds.  It may never be truly stable, it may be best if it always stays a landrace variety at least to some extent.  I hope that some dedicated seed saver somewhere will see the merits of Immali Corn and continue to grow it after I am gone.  Perhaps I should tell you what i hope to achieve in this variety.

So if I can get more of the cobs to look like the one above, and get the taste to be a bit more consistantly amazing, what else have I tried to include in this variety?

I wanted a reasonably small plant that was productive.  I figure people have less land these days so need small plants that are highly productive.  While 12 foot tall monster plants such as the Giant Inca White corn is spectacular to look at, it is not practical for Suburban Joe to grow in the corner of his yard.  The Immali Corn only grows about 5 foot tall.  It is not a dwarf plant, but it is not a giant either, I think it is a nice manageable compact size.

Immali Corn, reasonably short plants
I also wanted to create a variety that would be productive.  No point having a variety of corn that only produces 1 or 2 cobs per plant.  So far the Immali corn has produced an average of 4 cobs per plant.  I always plant corn too close and the weather is not always kind to corn, given better conditions and more space I think it could average a few more per plant.  Each stem produces 2 good sized cobs on average (some only 1, others 4), but then this variety is very prone to tillering (growing several stems).  This is probably a bad thing if you plan to harvest using a combine, but it is a great thing for home gardeners who harvest by hand.  It essentially means you get several times the corn from the same amount of space.  I am deliberately selecting for plants that produce more tillering as it is this trait that has helped raise the average number of cobs per plant.

 As well as a great tasting corn that is productive and takes up little space, I wanted something that was good to look at.  The cobs needed good colour, which was the primary reason behind this project.  One of the bonuses to using a coloured landrace as one of the initial stock was that the tassels sometimes are purple, it makes the plant look a bit more ornamental.

Immali Corn tassels and cobs
Immali Corn silk
Some of the cobs also display coloured silk.  I do not know if I will be able to keep this trait in this variety, but I will if I can.  It is one of the least important things I would like in the variety, but it does add something special to it.


Where can you get Immali Corn seeds?

This variety is reasonably stable now.  The last two times I have grown it I have only seen one plant that was taller than normal and the cobs all look and taste the same.  Seeds are now available through my For Sale page.

I think that you should breed some type of vegetable that you like.  Perhaps don't start with corn unless you are already experienced in breeding and saving seeds, perhaps start with a tomato or some beans or something simpler like that.  You don't need any fancy equipment, I certainly don't use anything special.  You don't need formal training in Botany or Horticulture or Genetics like I have, but you can still produce something amazing that can be treasured and passed on to others.

Skirret - a forgotten perennial vegetable


I have never met a person who dislikes Skirret (Sium sisarum) and I don't expect this to change.  Very few people in Australia grow skirret or have even heard of this remarkable vegetable, but those that have tried it all seem to like it.

What is skirret

Skirret is primarily an ancient root vegetable, but the leaves, stems and seeds are also edible and tasty enough in their own way.  This perennial root crop was grown and eaten across most of Europe for centuries prior to the Spanish conquest of South America.  After this time potatoes largely replaced skirret for a number of reasons.

Skirret is a perennial vegetable which, unlike many other perennial vegetables, also freely sets viable seed each year.  Most people who grow skirret reproduce it by breaking the plant into many smaller plants after harvest and replanting them.  Similar to yacon, the part you eat of skirret is different to the part you plant so you can increase the number of plants each year easily while still being able to enjoy the full harvest.

Seed grown skirret displays a lot of genetic diversity, I assume this is because no real breeding work has ever been done on it and it is mostly propagated by division rather than seeds.  Serious breeding of vegetables often results in highly inbred strains which contain all the desired traits but have little to no genetic diversity.  Sometimes this deliberate selection goes a little too far and the plants become highly susceptible to inbreeding depression (such as has happened to carrots and corn), other times it does not appear to bother the plants too much (such as tomatoes or beans).

What does skirret taste like

I am bad at trying to describe what things taste like and it has been a while since I last ate skirret but I will give it a go.  Raw skirret tastes kind of like carrot or parsnip or when cooked a little like sweet potato or potato, but skirret is sweeter than any of them.  That is probably not a great description as carrot and potato taste nothing alike.  Many people use skirret in the same dishes that potato, sweet potato, parsnip or carrot would be used.  Skirret is by far the most delicious roast vegetable I have ever eaten.

Skirret also used to be used for deserts and the like, but I am not exactly sure how/what they do with it in these meals.  As mentioned earlier, most of Europe grew and ate skirret until the potato came along so it has a long history behind it as a food plant.

Skirret contains reasonably high levels of sugars and tastes rather sweet.  When the Germans were searching for alternative plants to sugar cane they reported that skirret ranked below the white 'sugar beet' but above red beetroot.  Some of the common names for skirret translate into things like sweet root, water parsnip and sweet water root.  From these names you get the impression that skirret is sweet and likes to grow near water.
At this point I perhaps should have re-potted the plants separately

You can see the plant in the middle is already starting to divide

Problems with skirret and how to overcome them

Skirret can have thin roots, these can be a pain to prepare for a meal.  The roots are always long and there are always copious amounts of them, but if they are too fiddly to prepare no one will bother to grow or eat this remarkable plant.

Skirret can have woody cores to the roots.  Some people do not mind this, they cook the skirret and strip the roots with their teeth and discard the core.  I can't be bothered doing this and wont eat a vegetable which requires this kind of treatment.  First year plants grown from seed tend to have the woody core, as they age the core gets smaller or apparently even disappears in improved strains.  Lots of water seems to help prevent any woodyness at all.  Considering that this plant grows in marshes in the wild it makes sense that soil moisture would be beneficial.

Skirret loves cooler weather, I don't think it matters how cold it gets the skirret is never bothered.  It goes dormant over winter and is dug/harvested/divided during that time.  It does not love the heat.  As I currently live in an arid climate, lots of heat and very little water, growing skirret takes a bit of work.  Growing in part shade, or in a styrofoam box to help insulate the soil can help this plant to grow in less than ideal climates.  I have it growing in a pot which I can submerge in water on hot windy days.

Skirret is a plant that would benefit from some serious breeding work.  Pretty much every problem it has should be simple enough to overcome if someone puts the time and resources into breeding improved skirret varieties.  I honestly think if someone was serious about breeding skirret that it would only take 3 or 4 years to turn skirret from its current form into something truly remarkable.  If you ever do this breeding and grow improved varieties of skirret let me know as I would love to buy your plants or seeds.

Everything looks good


Breeding potential of skirret

One of the great things about skirret is how happily it sets seed each year and it produces many seeds even if only one plant is growing.  Being in the Apiaceae family they produce copious amounts of seed if allowed, similar to a carrot, but in skirret the seed seems to display a lot of genetic diversity even if obtained from a single plant.

Most people who grow skirret do not grow from seed, instead they find a plant and do not let it flower so that all the energy is put into root development.  I think this is a mistake as it is not difficult to find a nice skirret plant, divide it and let one of the divisions go to seed so that you can continuously improve your stock.  Leaving a single plant in your patch to flower is not that great an imposition.  While letting several plants flower would be best, a single plant flowering and setting seed would still give a crop of diverse seedlings from which to cull and only keep the best ones.  The flowers attract a lot of beneficial insects so leaving a single plant in the back corner to flower is of benefit to the rest of your vegetables.

Skirret grows many edible roots which are nice and long, so there are no issues with root length or number, the problem comes from them being too thin and often having a woody core.  It should be possible to breed for superior varieties with fatter and less woody roots.  First year plants are more likely to have woody cores and plants that do not get enough moisture will also have a woody core so selecting for lack of fiber can be a bit tricky.  That being said, many people who have selected for improved plants overseas only do so for about 2 generations and then have plants that they are happy with.

I do wonder if skirret was grown using aquaponics or wicking bed if the woody core issue would be completely resolved due to constant access to water.  If this were to be the case then skirret breeding could focus on fatter roots, having one single focus should mean that improvements are made a lot faster as culling can be more harsh.

One of the issues we have in Australia is that so few people grow skirret that we probably have a bit of a genetic bottleneck.  Hopefully the natural genetic diversity on this plant will ensure that we can still select for improved varieties and make ground reasonably fast.  I would love someone to take on skirret and breed some improved varieties, if the woody core could be bred out of skirret there is no reason that people would not grow it in backyards or even for market gardens.  As mentioned earlier I have never heard of anyone who dislikes skirret, improved varieties could make this crop more common once again.  Skirret does not always cope with summer in my climate so does not always flower (or necessarily even survive) so I probably wont do a lot of serious breeding with it.  That being said each year my skirret does flower I will save and plant seed from the best plants and cull the weaker plants.

Where to get skirret in Australia

People who know a lot about rare vegetables often tell me that skirret is not in Australia, and due to problems importing the seed that we will never be able to grow skirret.  I don't know how to respond to them as I have grown skirret before and I am also currently growing skirret.

I sell skirret plants over winter on my for sale page.  It is difficult to find skirret plants for sale in Austraia.  I also save seed from my best skirret plants each year to sell on my for sale page.  Each year my plants are getting better as I cull any under performers and only breed from the best.

At some stage I will include some growing notes on skirret.  If you have never tried skirret I think you should get some and grow it.

How to grow Babington's Leek


Babington's Leeks (Allium ampeloprasum var. babingtonii) are amazing little plants, I wrote another post on them and thought I should describe how to grow them.  They are edible and perennial and a bit more interesting than a regular leek.  Unfortunately they are on the brink of extinction in Australia and many other parts of the world.  I am selling small bulbils of Babington's leeks in the hope that other people will grow and enjoy them and help them to become less rare.

Here are some notes on how to grow them, please note that I am no expert on Babington's leeks, if something I say does not work feel free to try something else.  If you find some other way to grow them that works better please let me know and I will gladly pass this information on to anyone who wishes to grow them.

This is only a brief description of how to grow Babington's leeks that has worked for me.  For information on how to grow any other perennial vegetables please go to my growing notes page.  To buy Babington's leeks or other perennial vegetables, herbs, heirloom vegetable seeds, water kefir grains or milk kefir grains etc please go to my for sale page.

Babington's Leek bulbs - should flower next year

Growing Babington's Leek from from Bulbs
At this stage I do not have enough plants to sell mature bulbs but figured I would mention it for when your plants are larger or if I ever have enough to sell them too.  This is simple, plant the bulb a few cm deep and give it 15cm to 20cm or so from its nearest neighbour.  Plant it about the depth of the bulb's width, if it is too shallow it will drag itself deeper with the use of contractile roots.  Give it plenty of water, sunlight and mulch.  You should be able to harvest the leek by cutting it near the soil and have it re-sprout, if you get the timing right and the bulb was large enough it should still send up a flower stalk.  Each year if all goes well the underground bulb should divide into 2 or 3 mature bulbs for you and they may grow a few other smaller bulbs too

Babington's Leek will die down to a bulb in summer, it may be possible to convince them to grow through but I have not tried that yet so can not comment.  If storing the bulbs be careful not to leave the bulbs out somewhere to dry out too much, also be careful not to leave them in soil that is too wet as they may rot.

Growing Babington's Leek from Plants
If I have too many bulbils left over that sprout I plan to sell them as small plants.  Much like any other variety of leek, plant it reasonably deep to encourage a long white shank.  As above, plant 15cm to 20cm from its nearest neighbour, any closer than this will stunt the plant a little.  Plenty of sun, water and mulch will ensure the fastest growth rate.  During the first year they will be small and may not put on much growth above ground, this is normal.  They will mostly take 2 or 3 years until mature enough to flower.

Babington's leek bulbils - note the small size

Growing Babington's Leek from Bulbils
I mostly sell bulbils of the Babington's leek, these are tiny leek bulbs that have formed on top of the flower stalk.  For this reason I will go into a little more detail in this section.

Each bulbil will most likely be genetically identical to the parent (although slight mutations may occur from time to time).  The bulbils are tiny, probably around the size of a pea but sometimes even smaller.  Bulbils are produced in early Summer but will not grow or do anything until Autumn or Winter.  They are ready when they fall from the flower stalk, I sell them when they are ready and will store and grow anything that is not sold.  If you buy bulbils as soon as they are ready you have two options: you can plant straight away or you can store them for later.  Each method has its merits and dangers, I will try to do a little of each to work out what is best.
Babington's leek bulbils
Storing the bulbils gives you the peace of mind that they will not be eaten by anything or rot in the soil but runs the risk that they will dry out and die.  You also run the risk that they will not be in the soil when they are ready to grow or that they may not receive whatever signal they need in order to resume growth.  Some bulbils will look green, others will develop a brown outer skin.  I assume that the green ones will not cope with storage as well as the brown ones.  I also assume that the brown ones will be less likely to wake up when it is time to grow.

Planting the bulbils immediately runs the risk of rotting or being eaten by earwigs or whatever but also ensures that they will not dry too much and they are ready to grow when they need to grow.  I plant the bulbils a little under the soil surface or sometimes directly on top of the soil in the light.  I have heard that a grower overseas normally plants them 2 inches deep.  I urr on the side of caution, if they are not deep enough they will work it out or I could dig them and replant them when they are larger, if they are too deep they may not have enough energy to reach the sunlight.  It is best to plant them with the growing tip pointing up, quite often it is difficult to tell which way is up and in these instances it is best to plant them on their side.  Planted on their side they will work it out, planted upside down they may die.

No matter what you chose to do the bulbils will not do a great deal of anything until Autumn or even Winter/Spring.  Occasionally they may begin to grow in late Summer but only if the weather is cool.   Babington's leeks are often rather small looking plants in their first year and the next season are far larger.  The bulbils will often take 2 to 3 years to be mature enough to flower, that being said if they are very happy they can flower in their first year.

Growing Babington's leeks is simple
While it sounds like a lot of work it isn't, most people who grow Babington's leeks have a patch of them and pretty much ignore them other than to harvest them and to marvel at their amazing flower head.  Often overseas growers (I do not know any other Australian growers) tell me that Babington's leeks thrive on neglect.  I figured I would go into a bit of detail so that you have the best chances of harvesting leeks as soon as possible.  I also want to make sure that if someone buys Babington's leeks from me that they know what to expect and do not rip the plants out when they have not flowered in the first year from bulbils.  The pictures of the bulbils next to the measuring tape will help to ensure that if anyone buys bulbils from me that they know exactly what they are buying.

If you have any questions please feel free to ask, while I may not know the answer I will do my best to tell you what works and does not work for me.
