Allium aflatunense is a 36-inch-tall (0.9 m) bulbousperennial plant with basal, straplike leaves, and hollow, slightly ribbed scapes (flower stems). The flower heads are dense, globular umbels, about 4 inches (10 cm) 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.
Allium aflatunense is often confused with A. hollandicum.
Allium aflatunense is generally hardy in USDA zones 4–8. The plant is suitable for use as a cut flower. While it prefers alkaline soil, it can tolerate poor soil conditions, as well as part shade (though it does best in full sun).
