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.
