The Cliff Onion has a delicate beauty when in bloom, resembling a starburst effect. Sometimes this plant is called the 'Prairie Onion,' however it is more typically found along rocky cliffs and limestone bluffs near rivers in Illinois. The foliage and bulb of this onion are edible, if somewhat strongly flavored. The Cliff Onion differs from Allium cernuum (Nodding Onion) by its more erect inflorescence and slender leaves. It resembles Allium canadense (Wild Garlic), but doesn't produce any bulbets in the infloresence. The Allium spp. from the Old World, such as Allium vineale (Field Garlic), have round hollow leaves, while those of the New World have flat solid leaves. Return
