(Drumstick Onion, Round-headed Garlic)

The drumstick onion, a bulbous perennial, is grown for its dense, egg-shaped clusters of small, greenish-pink to dark-red flowers, which bloom in the summer on tall flower stalks that emerge from a basal clump of long, linear green leaves. When crushed, the leaves and stems have the familiar, pungent fragrance of the onion family. The drumstick onion is native to Europe, Africa, and Asia, where it grows in full sun and well-drained, often sandy soil.
