Allium christophii

Comment from Miriam Mesa-Villalba

The onion family is a large one, with almost 300 species growing wild in the northern hemisphere. This species produces one of the most dramatic flowers of the family. It is an important nectar source and has the added advantages of being hardy and drought tolerant.
