Actually, I may have had some success. Unfortunately, the only way to photograph the differences would to be by cutting one of each type and putting them together on a consistent background, so I’ll just describe it.
The wild species, I’m fairly positive is allium canadense although mine does not look exactly like these, mine has light purple rather than white flowers. I found it several years ago growing in a creek bed and brought both seeds and bulbils home and have been growing it from both since then. The bulbils that I found and 95% of all I’ve seen are very spherical and light green to grey.
Last year I found some that were more pointed. I planted those and this spring noticed those plants have slightly different color, a bit of blue cast. Bulbils have formed and flowering is about done this year and the 95% are just the spherical round ones with flower stems protruding from between them, all as usual. The bluish ones have grown leaves out the top of each pointed bulbil and unfortunately are not flowering at all.
Bummer, what I think might be a cross with the wild ones as mother are not blooming. Those in the wiki picture are interesting in that they seem to have the pointed bulbils but also flowers. I’m not at all sure I know what I’m talking about, perhaps it’s just variation in the species. Still, I will endeavor to persevere.
