Allium crispum is a species of wild onion known by the common name crinkled onion. It is endemic to California, USA, where it grows along the Central Coast, often in clays and serpentine soils. This onion grows from a bulb one to one and a half centimeters wide and sends up naked green stems topped with flower clusters of many flowers, each on a short pedicel. The flowers are magenta in color and have six triangular petals. The inner three petals are smaller and crinkled like cloth and may curl under.
