I grew allium 'Purple Sensation' this year and loved it so much that I want to try a few more varieties. Do you like Allium sphaerocephalon? I'm in zone 7b, and I see that it usually blooms in July. For my zone, that probably means June, don't you think?
Anyway, do you like it? Are the blooms large enough to enjoy? How many bulbs do you like to mass together?
