Allium caeruleum (aka A. azureum) Blue-flowered Ornamental Onion

Allium caeruleum (syn. A. azureum) (Blue Globe Onion)

Found on dry slopes, plains, and steppes of Central Asia, this Allium offers 1.5” spherical clusters of tiny flowers of a startling true sky blue in late spring and early summer and complement all of the warm colors perfectly. Tuck them among clumps of summer-flowering perennials where the Alliums’ withering foliage will be hidden by the expanding perennials, or plant a mass of them in a larger garden. Long-lived, drought tolerant and deer and rodent resistant, this species is hardy to Zone 4 and attracts bees, butterflies and hummingbirds.
