Great introduction of Mark McDonough, Allium collector and breeder from Massachusetts. Parentage of this cultivar is unknown, but tracks of genes of Allium nutans (native to European Russia to east China) and Allium lusitanicum (Europe from Northern Portugal to Ukraine) can be recognized.
Looks great in smaller groups, as well as single clumps when they repeat in the flower bed. Can be used as groundcover, even when it's not fast grower. Great combinations are with medium sized grasses (Bouteloa, Eragrostis,Muhlenbergia, Schizachyrium, Sporobolus), perennials like smaller Asters, Asclepias tuberosa, Coreopsis, Monarda bradburiana, Ruellia humilis, and many others.
