Perennial to USDA zones 4-8. Blooms late spring to summer. Onions in the flower garden? Most definitely! This showy 18″-24″ tall ornamental native onion will brighten any garden with its showy clusters of lavender pink (and occasionally white) nodding flowers. An excellent choice for borders, wildflower gardens, meadow plantings, water-challenged xeric gardens, rock gardens, or as a pretty accent in the vegetable bed, you will enjoy it for its attractiveness and the fact that both its leaves and flowers are edible. It thrives in sun or partial shade and in a variety of soils. Attracts bees and butterflies.
