I tend to leave the flowers in mine because I like the way they fade. The double one seems to be sterile but the single one is setting seeds this year.
I thought they were quite hardy plants but it seems lik of the three that I planted last year, only one seems to have made it through the monsson season. It seems also to have killed my asiatic lilly too.
I think you are right Figrat. Checked a similar plant on my way to work and if you crush the stem it smells garlicy. Is this plant invasive or is that the wild garlic?
I still don't understand how to search on it.
Could the second one be a allium cowanii but pink?
Lord that site is massive. Tried to use it on my phone. Not a good idea. Thanks for the tip. I'll have a look tonight.
