Allium...

Of all the spring-flowering bulbs I can plant in the fall,

I love alliums (ornamental onions) the most.

Allium is the onion genus, with about 1250 species, making it one of the largest plant genera in the world. They are perennial bulbous plants that produce chemical compounds (mostly cystein sulfoxide) that give them a characteristic onion or garlic taste and odor, and many are used as food plants. Allium is classified in family Alliaceae although some classifications have included it in the lily family (Liliaceae).Allium species occur in temperate climates of the northern hemisphere, except for a few species occurring in Chile (as Allium juncifolium), Brazil (Allium sellovianum) or tropical Africa (Allium spathaceum).
They can vary in height between 5 cm and 150 cm.
