This document summarizes information about the Crinkled Onion (Allium crispum), a native California wildflower. It is a clumping perennial bulb that grows 1 foot tall and wide, with strap-like blue-green leaves and bright magenta flowers in spring. It is well-suited for dry shade gardens under trees and prefers clay or rocky soils, requiring a dry period after flowering. Propagation is easy from seed in winter or by separating bulbs in fall.
