True Potato Onion Seed
In 2013 some of my potato onions flowered. It is the first time I have ever seen a potato onion flower so I was very excited, I wrote a little about it on a blog post called Potato onion seeds. I planted about half of those seeds in Autumn and nothing germinated, I was more than a little disappointed but there was nothing I could do.
I planted the rest of the seeds in Spring and some of them have just begun to germinate. I don't know how many will grow but at this stage it looks like only a small number. I could not be more excited about this. To make things even better, some of my original potato onions have begun to flower again this year! This should hopefully give me some more seed to try and grow next year. Hopefully they will flower more often so I can have seed grown potato onions to begin selecting for traits I want to see in them.

Everlasting Onion Seed and Bulbils
Another perennial onion I grow are the amazing Everlasting onions. They flower each year but never produce seeds. They have been grown by many different people in many different climates for well over 30 years and have not set seed and do not produce top sets. They rapidly split in half many times throughout the year so are simple to multiply without the need for seeds.

Last year from several hundred flower heads my everlasting onions actually produced some viable seeds. I planted most of the seeds and ended up with 7 seedlings. So far I can not see a lot of variation between the seedlings which I find rather odd. Some are slightly larger than others, some are slightly brown whereas others are slightly red, but this happens throughout the year with regular everlasting onions so is nothing different. They are still very small so perhaps I will notice differences as they grow, or perhaps they will be very similar to the parent, only time will tell. As mentioned above a lot of alliums were flowering at the same time so I would have expected them to cross a little and result in some unique perennial onions.

Babington's Leek (Allium ampeloprasum var. babingtonii)
One of the perennial leeks I grow is Babington's leek, I should write a blog post about them but probably wont for a while. I am not aware of anyhere in Australia that currently sells Babington's leek so if I ever have enough I plan to sell them so that more people can grow and experience these amazing plants. They are a kind of wild leek that has been semi-domesticated, when it flowers it grows tiny bulbils on the flower head instead of flowers, kind of like the leek version of tree onions.
I heard of Babington's leek years ago and tried to track down some to grow. One place had them for sale for more than I was willing to pay, but I contacted them anyway and they had sold out. That place stopped selling plants altogether shortly after. I emailed them and asked if I could get in touch with their supplier and was told no. They believed that this variety of leek had died out in Australia completely and they wished me luck in finding any.
When the weather cooled and the plants began to grow I had increased my stock from 5 tiny plants to 6 plants which ranged in size from tiny to reasonably large. I had hoped that more would have grown from the roots, but that was not to be this year. I am told that they will divide a bit each time they die down and many people increase their numbers in this way. I am assuming that mine did not increase in number much as they were posted late in their season so they put their energy into establishing rather than dividing.
This year one of the plants is beginning to send up a flower stalk. I have told the kids not to go near this plant and am concerned that they may remove it or damage it and I will have to wait another year to see what happens next. Regardless, I have at least one plant of flowering size and it should flower each year from here on. I am guessing that if all goes well the other plants will be flowering size next year as each of them is now larger than the ones I started with.

Chives (Allium schoenoprasum)
I don't have a lot to say about these little guys. They are nothing special, they are not even a special type of chives, but I like them. They die down to tiny bulbs each winter and grow again when the weather warms up a little. Apparently they are the smallest species of edible onions. I would like more of them so am letting some of them flower in the hope of either collecting the seeds or just letting the seeds fall and grow by themselves.

Spring onions (Allium fistulosum)
Spring onions are, in my opinion, the poor cousin of the everlasting onion. They are edible, useful, hardy and perennial so are not without their charm. I had some plants at our previous house that were 3 or so years old. Prior to moving here I saved their seed to bring with us. I planted them during the first few weeks after we moved in and they have been growing ever since. I do not have the heart to kill them as they are perennial and require very little looking after, so they have stayed where they are not doing too much. They produce viable seed each year, I used to collect the seed but recently have not bothered as everlasting onions are far superior.
Spring onions are perennial onions, we used to eat their leaves and white shanks. The problem is that their leaves get too thick and coarse after their first year and I do not know how to fix that other than planting new seed each year and killing the parent stock. I have cut some to the ground, when they sprout they are think again.
Everlasting onions have far thinner foliage and it is never course. Spring onions do not have the ability to produce bulbs whereas everlasting onions die to bulbs each year if I want them to and will keep growing if I water them a lot over summer.
Tree onions are an interspecific hybrid between spring onions and bulb onions that was made accidentally hundreds of years ago. I have often thought of trying to recreate tree onions with better parents but I doubt I will ever try to do that as I have a lot of other, more deserving things going on in the vegetable garden.

Giant Russian Garlic (Allium ampeloprasum var. ampeloprasum)
This is great stuff. Botanically it is a type of perennial leek, but for everyone else it is a massive garlic that is mild in taste. Apparently this can grow in more tropical places where regular garlic can not.
Many people say that they can not produce seed but this is not true, each year mine produce a tiny amount of seed which grows into new plants. The seed seems to grow true to type even when there are other types of leek flowering at the same time.
|Russian Garlic almost ready to flower and die down|
Some people complain that Giant Russian garlic is too mild. I have found that if I plant them early and they grow through some frost the taste is a lot more intense. Apparently putting them in the fridge a few weeks prior to planting can have the same result if they are grown in frost free areas.
I have successfully (and accidentally) stored the bulbs for over 18 months before we moved here. I stored the cloves somewhere and forgot about them, by the time I noticed them it was too late to plant and I had no more garden space so I waited for the following year. From those, 100% grew and the plants were indistinguishable from the fresh ones. While this is far from ideal, it shows how easy these things are to grow.

Perennial vegetables for sale in Australia
If you are interested in growing some of these I do sell everlasting onions, tree onions, perennial leeks, giant Russian garlic, garlic chives, two types of potato onions and a bunch of other perennial vegetables (and some heirloom vegetable seed) on my for sale page. When I have enough I plan to also offer Babington's leeks but that will have to wait for at least a few months to see what happens with this flower. If the potato onion seedlings or the everlasting onion seedlings end up as anything remarkable I will sell them too, but I dare say that is a while off as I would like to grow them out for a few seasons to see how they perform and evaluate if they are worth keeping.
