Wild/Perennial/Babington leeks

I started with 6 Babington bulbils about 15 years ago. I still don't have a good sized clump of them. They're not one for a quick return!
I've planted them, and the Elephant garlic  in several places around the garden (which is mostly tree covered) hoping to find a spot where they're really happy. When they are growing, I find it difficult to distinguish between the two alliums, its only when they flower that I know which is which.
We have an invasive allium here - Allium triquestrum (Three cornered leek) - that one spreads too well. I like it to look at and to use in cooking, but it has to be kept in check or it will be everywhere. Be warned.

Sorry to hear about the slow-starting habit.  I was hoping they might be a prolific as Egyptian walking onions (Allium proliferum ) seem to be here.  I bought 10 small bulbils of those two years ago and put them out in a pot when they arrived in the spring.  They came up, but did not produce bulbils that first year.  Last year, each of them did, with some having bulbils on bulbils and a few even going to a third tier.  I replanted the bulbils as soon as they matured and divided the original bulbs and replanted last fall.  I now have 12, 3-gallon pots full of them (includes original bulbs, and bulbils from this year and last) at the house and started putting them out in the orchard rows this year.  I'm going to attach a picture of some on the ones at the house in town.  I just counted 26 individual plants up in the one pot that has the volunteer dill growing in it.  All told the 10 original bulbils must have yielded more than 400 plants now.  They are incredible multipliers. 

I was hoping, in the right setting the Babingtons would adopt a similar reproduction scheme, given that they reproduce by topsets too.  I was thinking that I read that they were plants that appreciated a full-sun spot and were not overly needy when it came to watering requirements.  Is that your understanding?

Funny you should mention your three-cornered leek, it is also on my list of allium species to give a try to.  Invasive does not bother me.  I have 165 acres of my own to fool with and another 50+ that I caretake and can use as I see fit.  I can always just mow down anything that wanders out of an area I don’t want it in. 

Over here, most folks consider wineberries invasive,  I just consider them a non-native, but useful, food resource.  Mustard garlic holds a similar spot, although, I am much less inclined to eat it.  But I’ll take a wineberry pie or wineberry-apple-mint jelly anytime you put it in front of me.

If you’d want to drop a few seeds from (that’s right isn’t it, they reproduce by seed?) your three cornered leek in the mail, that is a letter I would love to receive.

Good news, I hope.  Someone in Wales got back in touch with me and I think they are going to mail me a letter with some Babington bulbils.
