Oriental Summer Jade Spinach days to maturity

This winter I am growing a bunch of different leaf vegetables.  Among these leafy vegetables was spinach, as this always performs well for me over winter.  

Normally I get whatever variety of spinach seed that is available, and for no particular reason I rarely save spinach seed myself.  This year I chose Oriental Summer Jade spinach.  

I chose this variety as I don't have much luck growing spinach over summer, and this variety is meant to handle the heat well.  I am growing it over winter at the moment, and it is performing as well as any other variety I have grown.  

The days from planting the seed in the garden until picking the leaves is below.  Being in Australia, the date is written Day/Month/Year.

Oriental Summer Jade Spinach

For some reason I don't often get around to saving spinach seed, which I always regret after a few years when I plant the last of my seed and need to buy more.  Spinach tends to be dioecious, which means some plants are female and other plants are male.  There aren't a lot of vegetables like this.  Occasionally some spinach plants, and some varieties of spinach, are monoecious with female and male flowers on the same plant.  

For a long list of days from planting a seed until harvest of many different vegetables and berries, please look at my Guide on Days to Vegetable Harvest.  As above, I recorded days from planting the seed until harvesting.

What do tearless onions taste like

I wrote a previous blog post about Happy Chop Tearless onions being released in Australia.  As mentioned in my previous post, this is not a GMO and is not an F1 hybrid, it is a stable variety that is meant to breed true to type.  

There are two things I wanted to know about tearless onions: are tearless onions really tearless, and how do tearless onions taste.  

I have since been able to buy some tearless onions, eat them, and thought I would write a review of them.  Unlike the previous post, I took all of these photos.  

What do tearless onions taste like

Are tearless onions really tearless?

I can confirm that the tearless onions were tearless.  I cut them, I handled the cut pieces, I ate some raw as well as ate some cooked, and they were indeed tearless.  Even rubbing a little onion juice below my eye did not cause any irritation.  They are completely tearless.  

Tearless brown onion

What do tearless onions taste like? 

When eaten raw, tearless onions taste very sweet, and a little oniony.  My kids ate some raw, and kept coming back for more.  They were crunchy, almost like eating a mildly onion tasting apple.  They were really enjoyable raw.  I plan to grow some so my kids can eat them raw - never thought I would say that about an onion.  

I fried some tearless onion to see what they were like.  My house smelled like cooking onion, the texture was the same as any onion, all of which is good.  The taste was mild and not very oniony when they were cooked.  They were still quite sweet at this stage, but the onion taste was very mild.  

I have not grown any yet, so cannot comment on how the leaves taste.  I am guessing that they would be sweet and milder than onion chives.  I need to grow some out before I can know for sure.  

Tearless onion

Onion base growing roots

As you can see in the photos above, I cut the base off the onion we ate, and am attempting to sprout it.  So far the roots are growing well, and the leaves have not done much growing yet.  Often, sprouting the base of an onion will flower and set seed.  This variety is said to breed true to type as it is a stable variety and not an F1, so I hope to grow more of these rather than having to buy them.  

So, now you know what tearless onions taste like.  What fun!

Solanum acroscopicum - wild potato relative

I sometimes grow potatoes from true seeds, each seed grown potato is unique and can create a completely new potato variety.  I do a little potato breeding, and have developed some nice varieties that taste better than anything you can buy from the markets and better than any variety you have grown at home.  

Supermarket potatoes, and most heirloom potatoes, are tetraploids.  I grow some tetraploids, which yield high but lack any great flavour (I grow some tetraploids which taste almost as good as a diploid).  

I grow some diploid potatoes, which taste incredible and often have remarkable colouration, but often tend to have lower yields and smaller tubers (some of my lines are yielding higher than some tetraploids).  

As well as these, I also grow a wild potato, Solanum acroscopicum.  I don't think it has a common name.  This potato is very rare, and not many people in Australia grow Solanum acroscopicum.

Solanum acroscopicum flower 

Solanum acroscopicum produces tubers with white skin and white flesh, mostly round or oblong, and small to medium size.  The skin is smooth and simple to clean (or simple to peel, if you are so inclined).  The taste is good but about as uninteresting as regular potatoes.  

Small yields of unimpressive tasting potatoes that don't have vivid colours makes it sound like it is not worth growing.  Even so, this variety has a few features that make it well worth growing.  It is great in smaller spaces, the plant looks nice, and its certainly worth considering in breeding projects due to its disease resistance.  

Solanum acroscopicum grows large, pretty flowers.  This plant would not look out of place in a flower garden.  I keep forgetting to take photos when it is covered in blooms (or when there are other flowers I can hold next to it for comparison).  Growing food in a flower garden is a good idea.  

Solanum acroscopicum flowers

The plant looks like a potato plant, but with pointier leaves.  The leaves mostly point upwards, which helps keep the plant looking compact.  It grows rather short, neat/compact plants that do not tend to sprawl unless they are shaded.  Being such a compact and neat plant also makes it look good in a flower garden even when not in flower.  

It dumps all of the tubers very closely together directly under the plant, and very close to the soil surface.  It is a good idea to hill soil around them as they grow to prevent light getting to the tubers.  You don't have to search for the tubers, they are all together rather neatly.  Unlike most potato varieties where you always miss some when harvesting, it is simple to get every tuber as they are all so close together.  

Solanum acroscopicum - tubers get a little larger than this

Being such a compact plant, and dumping the tubers so close together and close to the soil surface, make it better suited to growing in pots than any potato variety I have ever grown.  Even growing in soil in the vegetable patch, there is far less digging as the tubers are all right there, all bunched together.

I am told that this species is much lower in toxic alkaloids than regular potatoes.  I have never eaten them when green, and do not encourage people to do this.  I only include the next sentence for informational purposes.  I have been told that it is so low in solanine that this can be eaten when green, when regular potatoes are highly toxic and would cause severe stomach cramps and intense vomiting.  This is important: if you try eating them green please be careful, please only eat a little at first to see how you go, and if it tastes bitter stop eating.  I don't eat them green, and I don't encourage other people to eat them green, but if you are going to do this please be careful.

Solanum acroscopicum growing in a pot of soil

Solanum acroscopicum has genetic resistance to many potato diseases and tolerates light frost better than many other potato varieties.  From what I have read, this species seems unaffected by things that would destroy regular potatoes.  If you are into potato breeding, this variety would be useful to consider due to its disease resistance.  

I grow everything organically, so am interesting in plants that are resistant to pests and diseases.  This makes it suitable to breeding, or for growing in the flower garden where you may not look after it all that well.  

Wild potato

I have grown these for a few years and have tried to share them with some enthusiasts who I have encouraged to share them further.  Hopefully they don't go locally extinct in Australia.  

I have reached a point where I will sell some seed tubers for growing (not true seed) through my for sale page when they are in season.  I am not sure what the rules are in each state for sending potatoes from NSW for growing, so you may need to look this up if you want any.  If you are in a state that does not allow them, I may be able to send ware potatoes for eating.  Again, not really sure about this so you would need to look up what is allowable in your state.

Protein comparisons in food

I don't think I eat enough protein.  My body craves more protein.  Protein is expensive.  You also need to ensure all the essential amino acids are present, either in that food or a combination of foods you eat, otherwise your body can't utilise the protein you eat.   

I looked into protein shakes to increase my protein intake.  They taste nice and they take less effort and time than cooking food, but they can be expensive.  The best whey protein (high quality, high protein, at a lower price) I can find provides 32 grams of protein per serving.  I wonder how that compares to meat, eggs, or even vegetables and grains.  

Below I have compared the protein powder to several meats, eggs, vegetables, and grains.  For reference, I included the websites where I found the details.  This post was mostly made as a way for me to keep these numbers handy.  

Picture from https://customequinenutrition.com/blogs/nutrients/intro-to-protein-amino-acids

I am interested in the grams of protein, so I included this in the comparison.  I noted if the food contains an incomplete protein, as this is very important.  Leucine is an essential amino acid that is important for building muscle, repairing muscle, and it is metabolised in muscle fibers, so I included it in the comparison.  I am also interested in iron content as I struggle to get enough iron.  Even though it makes no difference to me, I know a lot of people care about calories, so I included the amount of calories of each food.  

To give the comparisons some perspective, the recommended daily intake for a male about my size and age is roughly:

Protein 50 g
Leucine 2.4 g
Iron 8 mg
Energy 2,000 kcal

To make the comparison as useful as possible, I am comparing 100 grams of each food, except for the protein powder which is one 40g serving.

Results

In the above comparison, out of all the meats rabbit meat has the highest percentage of protein.  Rabbit meat contained the highest amount of leucine among the foods compared.  As far as iron content goes, squab is the stand out, followed by rabbit.  Rabbit meat is also low in fat.  

Unfortunately rabbit meat is very expensive here, and very difficult to find, so I would either have to breed rabbits or choose another meat.  In that case I would choose chicken.  Chicken is a cheaper meat, it is readily available, it is high in protein, and it is high in leucine.  

Buckwheat is incredibly nutritious for a plant based food.  Buckwheat is high in protein, it's one of the few plant based foods that is considered to be a complete protein, it's high in iron, and it's gluten free.  Nutritionally, buckwheat is pretty comparable to egg.  The protein in buckwheat is absorbed better than the protein in egg, which is almost unbelievable for a plant based food.  Sadly, in Australia buckwheat is not commonly eaten and is difficult to find.  Presumably this is largely based on political reasons as it is a very healthy food.  

Days to harvest Hon Tsai Tai

I grew some purple stemmed Hon Tsai Tai (Brassica rapa) this year and recorded the number of days from planting the seed until harvest.  

Recording the days from planting the seed until harvest is far more useful for home gardeners than the ambiguous 'days to maturity' which has different meanings depending on who is recording it and is often starts being counted from transplants of an unknown age.  

Hon tsai tai is a nutritious vegetable that can be harvested as a leaf vegetable, or for flower stalks that are used in a similar way to broccoli, so I recorded the days from seed to both.  

This quick growing vegetable is sometimes called flowering choy as it is a type of bok choy that is usually grown for the edible flower stalks.  The leaves taste like bok choy, but are a bit sweet.  I have eaten the flower stalks raw when the first flowers were just opening, and they tasted really nice.  I expected some of the stalk to be a bit fibrous at this stage, but they were tender and perfect.  

I grew this during the winter, night temperatures have dropped to -8C and the days have mostly been overcast and cold.  If grown in spring, I think the days to harvest would probably have been a lot less.

Baby bok choy and Hon Tsai Tai - baby leaf

Hon Tsai Tai and Bok Choy can and will cross pollinate, which means care must be taken if saving seed.  It should also be possible to intentionally cross the two, do a little culling/back crossing/rouging out of undesirable plants, and develop a vivid purple stemmed bok choy.  

I have a few breeding projects on at the moment, add while I would love to develop a tightly packed purple stemmed bok choy I am not sure if I have the space, time, or energy to put into another project.  Then again, I could leave a few of each to flower, cross at random, and self seed, then cull heavily...  

Have a look at my Guide on Days to Vegetable Harvest to see a full list of days to harvest various vegetables and berries in my garden.  As above, I recorded days from planting the seed until harvesting.

Tearless onions in Australia

'Tearless' onions are now available in Australia 

A quote from the paper - Production and characterization of tearless and non-pungent onion | Scientific Reports (nature.com):

We believe that these tearless, non-pungent onions not only will wipe tears away from the kitchen and the food processing facilities, but also will add a new dimension to the enjoyment of onion recipes around the world.

What fun.  I wonder if you could eat these raw like an apple.  I also wonder if the taste would be watered down significantly.  The US has been selling tearless onions since 2018, I am not sure if it is the same as these or if they have a different variety.  Perhaps someone from the US can comment and let me know if tearless onions are worth trying.  

These 'tearless onions' were not Genetically Modified.  These were bred from inducing a mutation, and then selecting and culling and self pollinating until the new variety bred true to type.  

To summarise how these tearless onions were bred:

• They irradiated seeds from “Super-Kitamomiji” onions and planted 1,500 seeds.  From these they selected the best 9 plants and culled the rest. 
• These were allowed to flower and set seed.  From these the researchers planted about 350 seeds.  Selected the best 18 plants and culled the rest. 
• These were allowed to flower and set seed.  From these they planted 1,078 seeds.  Selected the best 2 plants and culled the rest.
• These two plants were allowed to flower and set seed.  They appear to breed true to type.  
• They now have 2 lines of tearless onions that are being produced commercially.

As you can see, breeding a new anything takes large numbers, and several generations.  

One variety of tearless onions is to be sold in NSW and VIC Woolworths starting tomorrow!  I have no idea how they taste, the news says they are sweeter than regular onions.  

I want to get some, plant them, collect seed, and…you can probably guess the rest, plant breeding is a slippery slope. 

Tearless onions - not my photo

Edit to add: after writing this post I bought some tearless onions and got to taste them.  I wrote a blog post of what tearless onions taste like.  I also grew some of these onions, allowed them to flower.  Once the seed is ready I plan to offer it on my for sale page for home gardeners who would like to grow tearless onions themselves.  

Buckwheat nutritional information

Much like a seahorse is not a horse, buckwheat (Fagopyrum esculentum) is not related to wheat (Triticum aestivum).  Other than their common names, and that they are both edible, buckwheat and wheat don't have much in common.  

While buckwheat and wheat are both angiosperms (vascular flowering plants), that is almost where the similarity ends.  Wheat is a monocot, while buckwheat is a dicot, as far as flowering plants go you can't get much more different than that.

Both plants are edible, both can be eaten in similar ways.  Both are popular breakfast foods, as well as being popular for animal feed, and both feed a tremendous number of humans across the world every day.  Both have edible leaves and stems, but I want to discuss the seed/fruit of buckwheat.  

Wheat contains gluten, buckwheat does not.  Wheat is low in several essential amino acids (eg lysine and threonine) and is not considered to be complete protein.  

Buckwheat contains high quality complete protein with decent quantities of all of the essential amino acids.  Buckwheat is rich in limiting amino acids like lysine and arginine, which are in shortest supply in plant-based diets and is pretty rare among plant foods.  For this reason, buckwheat is considered to be a complete protein.

Some buckwheat that I grew

Buckwheat nutritional value

It is difficult finding nutritional data on anything that is overly consistent.  Sometimes these differences come down to what exactly is being tested, or different varieties, or seasonal variations, or even how the test was conducted.  For this reason I try to look up several sources of information.  Regardless of the source, you will notice that buckwheat is incredibly nutritious for a plant based food.

I found a website that listed the following nutritional value per 100g of buckwheat:  

Principle	Nutrient Value	Percent of RDA

Buckwheat nutrition compared to Grains

I also found a comparison of the nutritional value of buckwheat, rice, wheat, and maize.  I have highlighted the highest value in each row to make it easier to read. 

By in large, buckwheat appears to be more nutritious than any of the true grains that were tested in that sample:

Comparison of nutrition: Buckwheat, Rice, Wheat, and Maize

Buckwheat vitamins compared to wheat

To give a little perspective I looked up the Recommended Daily Intake (RDI) of a few vitamins and minerals that are present in buckwheat and listed the equivalent in wheat.  As you can see, buckwheat is far more nutritious than wheat.

Vitamin E (tocopherol) buckwheat 40mg, wheat <1mg, RDI 15-20mg with safe upper limit 1,000mg
Thiamin (B1) buckwheat 3.3mg, wheat 0.5mg, RDI 1.5mg
Riboflavin (B2) buckwheat 10.8mg, wheat 0.2mg, RDI 1.8mg
Niacin (B3) buckwheat 18, wheat 5.5, RDI 20 

Pantothenic acid (B5) buckwheat 11mg, wheat <1mg, RDI 10mg with safe upper limit of 1,000mg
Magnesium, buckwheat 390mg, wheat 138mg, RDI 400mg

Choline, buckwheat 440mg, wheat 14mg, RDI 550mg

Vitamin K (phylloquinone) buckwheat 7.00 µg, wheat 0.3 µg, RDI 80 µg

Vitamin A (retinol) like all grains, none.

Buckwheat compared to Oats

Oats (Avena sativa) are another popular breakfast food.  Oat is a monocot and is similar to wheat in many ways.  Unlike wheat, oats do not contain gluten.  Oats, much like buckwheat, are meant to naturally lower total cholesterol levels and improve HDL to LDL cholesterol ratio.  

I use buckwheat to make kasha for my breakfast each morning, which is similar to how many people eat steel cut oats.  I tried eating oaten kasha for some time, but found I was getting hungry early in the day.  When I make kasha using buckwheat I feel full for longer, which is nice.

I fount a web page with the following comparison table of buckwheat and oats.  Once again buckwheat comes out as an impressively nutritious food.  These results indicate that buckwheat is more nutritious than oats.

Buckwheat Glycemic index compared to grains

I have a little trouble with blood sugar, so wherever possible I prefer foods that have a low Glycemic Index (GI) and Glycemic Load (GL).

I found a peer reviewed paper comparing the GI and GL of buckwheat, barley, millet, spelt, bulgur, and couscous.  GI and GL are often used to assess diet quality in relation to the risk of diabetes, cardiovascular diseases and cancer development.

The lowest GI was found for buckwheat (34.7±8.2%) and barley (31.3±13.4%). The GL for these groats was 8.1±1.9 and 8.0±3.4, respectively.  The GI for millet, spelt and bulgur amounted to 56.2±20.6%, 69.8±35.0%, 64.5±36.8%, respectively, while for couscous amounted to 99.0± 36.0%.  The highest GL was observed for couscous (24.7±9.0).

The groats tested in that study classified barley and buckwheat as low GI food, millet and bulgur as medium GI food, spelt and couscous as a high GI food.  The study concluded that buckwheat and barley should be chosen the most often among these products, while the intake of couscous should be limited, especially by people with diabetes.  

Buckwheat is comparable to egg protein

100g of egg (about two eggs) contains about 13 grams of protein, which is similar to the amount of protein in buckwheat.  Both buckwheat and egg are eaten by people who are into fitness, strength training, and body builders.  

The absorbability of egg protein varies depending on how it is cooked, and is cited in literature as being between 50% and 90%.  The absorbability of the protein in buckwheat also varies in literature, possibly due to cooking methods, and is often cited as being around 93%.  Both buckwheat and egg contain good levels of all of the essential amino acids and are considered to be complete proteins.  

Conclusion

Buckwheat is incredibly nutritious for a plant based food.  If more people in this country ate buckwheat as an every day staple food they would be healthier and stronger.  

Buckwheat would be a valuable staple food in the diet of anyone who does not eat animal based foods or does not eat may animal based foods.  Buckwheat is simple to store, it tastes good, and can be used in a wide range of ways.  

I used to eat wheatbix each morning for breakfast.  Then the local shops ran out and I could not buy it for a few months, so I switched to oats, and then to buckwheat.  Since switching to buckwheat I have gained strength, I have lost fat, I have gained weight (presumably muscle) and am now staying up in the 'healthy' BMI range, my cholesterol levels have dropped, my HDL to LDL cholesterol ratio is now in the ideal range, my blood sugar levels are more stable, and I am less hungry.  

I plan to write another blog post at some stage on growing buckwheat as a cover crop and (according to research) a nitrogen fixer.  There seems to be little academic research on this topic outside of Russia and previous Soviet nations, but what research I can find is fascinating.  

I find the limited research into buckwheat odd considering the economic value of buckwheat, the amount of people it feeds (the FAO says buckwheat is a major food crop in the world), and how incredibly nutritious buckwheat is.  Given how much more nutritious buckwheat is compared to most other grains, I find it odd how limited its consumption is in Western nations where it remains a specialty food rather than a daily staple.  I assume this is mostly due to political reasons.  

How tall does asparagus grow

Asparagus grows much larger than you probably think.  Unless you grow asparagus yourself, you probably can't imagine how tall it can get.

I remember years ago reading about asparagus and being surprised to see the stated heights it reaches as being much shorter than what I have seen.  

Many places on the internet, including wikipedia, state it can reach 1.5 m (about 5 feet) tall, other places (such as Better Homes and Gardens) say it reaches 12 inches tall.  Asparagus grows far taller than this.  

I found this rather perplexing.  At the time we had orchards, and in them some asparagus grew that was much taller than any of those.  This asparagus had been there since before we moved in, given its location, presumably seed had been deposited by a bird.  We eventually moved from there and left the asparagus behind.  

Since moving to town I have started growing asparagus again.  I grow a few types of asparagus now.  The most delicious also happens to be the largest and most vigorous variety.  It is an heirloom variety called Precoce d'Argenteuil.  From seed it only takes about 6 months to reach 1 meter tall, and it produces the best tasting spears of any asparagus variety I have eaten.  

After harvesting some spears this year, I left a few spears to feather out so they can feed the crown for the following year.  I could not help but notice how tall this asparagus was.  I wanted to measure it and photograph it, but didn't want to take another frond so I let it grow for the remainder of the season.

Now that winter is upon us my asparagus plants have gone dormant.  This year they have gone dormant nice and early.  I was removing the old growth and decided to measure a frond.  There were a number of fronds on my plants that were around this tall.

The one in the photo reached around 282cm, or about 9 feet 2 inches.  That is pretty big for asparagus.  Certainly a lot larger than most places say they will grow.  

I don't look after my asparagus anywhere near as much as I should.  My plants are not pampered, they have competition from other plants, and I have not made any attempt to make them larger.  I certainly haven't done any breeding work with them.  

The strange thing is, I don't think this is the tallest asparagus I have seen.  I am pretty sure some of the ones we had at the orchard were much larger than this.

Not a great photo

It makes me wonder why so many garden books etc say the height of asparagus is so much shorter than they will actually reach.  As a gardener, these wildly inaccurate estimates can cause problems when planning what to grow where.  

Presumably the person writing about it does not have much experience growing asparagus.  Perhaps (as I suspect is the case with Better Homes and Gardens) the author has never grown asparagus themselves, and has probably never even seen asparagus plants growing.  This kind of thing is very common with gardening books and permaculture books, and the misinformation is often repeated by companies who sell plants (that have been grown by a contractor), and I find it rather frustrating.  When gardening books make up nonsense, or re-spout these inaccuracies, what else have they gotten wrong?

Some of my 6 month old asparagus plants

I only sell plants and seeds that I have grown and propagated myself.  While the information I provide is vastly different than you will find in books, it is based on actual experience.  I can tell you what does or does not work for me in my garden.  

Asparagus plants are dioecious, meaning that some plants are male while other plants are females.  Female asparagus plants tend to produce larger yields than male.  Female asparagus plants also tend to produce fatter, longer, higher quality spears.  Commercial asparagus farms only grow male plants (or super male plants) so they don't have to worry about seeds falling and choking the beds with volunteer seedlings.  Commercial asparagus farms usually grow low quality asparagus varieties, they really can't compare to the delicious asparagus varieties you can grow at home.  

New asparagus fronds already over 6 feet tall

I grow a few different varieties of asparagus.  Some are purple, some are green, all can produce tender white asparagus.  At this stage they are all seed grown, from seed purchased from reputable businesses to ensure the correct variety rather than a mystery cross.  

Late winter each year if I have any extra asparagus crowns I will offer them through my for sale page.  I sell a few different perennial vegetable plants, some berry plants, as well as some heirloom vegetable seeds.
