Allium aflatunense

Description
Allium aflatunense is a  tall bulbous perennial plant with basal, straplike leaves, and hollow, slightly ribbed scapes (flower stems). The flower heads are dense, globular umbels, about  across, made up of numerous star-shaped, purplish-pink flowers. It flowers in May and June, with seeds ripening in August. It is commonly sold as a bulb.

A. aflatunense is often confused with A. hollandicum.

Cultivation
