The genus Allium contains over 700 species of bulbous or rhizomatous plants. All possess flowers and foliage that smell of onion. Some species are grown for culinary purposes and others for ornamental purposes. Plants typically produce showy flower umbels on naked scapes rising above a clump of linear grass-like leaves. Ornamental Alliums generally range in height from 3” to 4-6’ tall.
Allium species occur in temperate climates of the Northern Hemisphere, except for a few species occurring in Chile (such as A. juncifolium), Brazil (A. sellovianum), and tropical Africa (A. spathaceum).
