Botanical Name

ALLIUM flavum

Plant Common Name

Fragrant Yellow Onion, Yellow Ornamental Onion

General Description

Yellow ornamental onion is a compact bulbous perennial grown for its bright yellow, wispy flower clusters that appear in late spring to summer. Each cluster, or umbel, bears up to 60 bell-shaped flowers with prominent stamens; the flowers nod down as they open. Its clumps of slender blue-green leaves grasp the base of each leafless stem.

This allium is native to Europe and western Asia where it grows in full sun and well-drained, often sandy, soil. Bulbs should be planted in the autumn under three to four inches of soil. This tiny beauty shines in the rock garden or mixed bed; plant it in groups to make a sunny statement.
