Description

Allium crispum grows from a bulb one to one and a half centimeters wide and sends up naked green stems topped with inflorescences of many flowers, each on a short pedicel. The flowers are magenta in color and have six triangular tepals. The inner three tepals are smaller and crinkled like cloth and may curl under. Anthers and pollen are yellow.[3][5][6] The leaves are narrow and linear, typically slightly shorter than the stems and about 1.5 millimeters wide.[7]

A. crispum reaches 10-20 centimeters tall.[8] Flowers typically appear between March and June in the US. The plant prefers part shade.[9]
