Depends on variety - Allium Purple Sensation flowers around April/May, Allium christophii about now, but most are spring through to early summer.

Mmmmm! Mine have only the leaves, no sign of flowers? :o((

Which Allium did you plant - there is one that flowers mid to late summer, and another that flowers mid summer, depends which one you planted.

Ha! Ha! Bamboo, I was waiting for someone to ask that question, the answer is I don't know, I'll have to wait till mid to late summer and see LOL, Thanks for the info :o))
