Largeflower Onion, Desert Onion - Allium Macropetalum
Allium macropetalum produces typically small but attractive bell-shaped flowers, mostly light pink but with a distinct, dark pink or purple vertical stripe along the middle. Each flower has 6 petals, and they occur in clusters (umbels) of between 10 and 20 heads. This onion can form extensive colonies, sprouting from a spreading root system. Like most allium species, the plant produces edible bulbs, raw or cooked. Favored habitats tend to be drier and less wooded than for many other species, and the plant is found across a wide area, in grassy or rocky environments.AmericanSouthwest.net
