Family

Liliaceae

Botanical Name

ALLIUM christophii

Plant Common Name

Christoph's Onion, Star of Persia

General Description

The star of Persia ornamental onion is grown for its huge globe-like cluster of shimmering pink-purple starry flowers, which rises like a flowery lollipop from a single leafless stem in the early summer. The large, strap-like gray-green basal leaves emerge slightly before the short-stemmed flower appears.

Alliums are onions and thus most have the familiar pungent fragrance when their leaves or stems are crushed. Star of Persia is native to Turkey and Central Asia where it grows in full sun and well-draining, fertile, often sandy soil. It is marginally drought tolerant once established. Plants are borne from bulbs and should be planted six to eight inches deep in the fall. Give this dramatic plant a starring role in the front of a mixed border or rock garden. Plant singly or in groups.
