Allium: Millenium Ornamental Onion


Selected as the 2018 Perennial Plant of the Year by the Perennial Plant Association for its beauty, durability and easy-peasy nature! Glossy, strappy leaves impart a wonderful texture in any sunny area. The leaves form an upright, tidy mound while long-blooming, lilac purple globe-shaped flowers in July and August attract flocks of butterflies and other beneficial pollinators. For best effect plant in groups of 3-5 with companion plants such as Black-Eyed Susan (Rudbeckia), Coneflower (Echinacea), Salvia, Sedum and Stachys. Another big plus is that deer and rabbits are repelled by the plant’s oniony smell!
