About plant names...

Prairie onion is native to North American prairies.

Identification: Plants are 12-18" (30-45 cm) high, growing in sandy soil. Like all members of this genus, plants have a distinct onion/garlic odor. Leaves are few, grasslike, near the base. They die back when the flower stalks grow. Flowers are rose-pink to lavender, in umbels that are ball-shaped, 2-3" (5-7.6 cm) around. Each individual flower is about ¼" (6.3 mm) in size. Sometimes the flowerhead is tipped over—”nodding”—making these plants resemble nodding onion (Allium cernuum). Bulbs are oval or cone-shaped, 1½" (4 cm) × ½" (1.5 cm) in size.

Edibility: Bulbs are edible, but very strong in flavor, and can be eaten when boiled. The leaves are edible, either raw or cooked, and the flowers made a good garnish on salads.
