Tough one, if only because there are so many allium. Onions, garlic, leeks, shallots, scallions, and chives all belong to the genus Allium, as do about 20 other species of food crops used around the world. Do you have the packaging the bulb/s came in?
Flowering onions (Allium spp.) are early summer perennials. We’d call that June to early July.
