Millenium Ornamental Onion
Allium 'Millenium'
Bold, beautiful, and pollinator-friendly, Millenium Ornamental Onion is a standout perennial that brings vibrant color and structure to the summer garden. This award-winning variety forms tidy clumps of glossy, strappy green foliage topped by globe-shaped clusters of bright rosy-purple blooms in mid to late summer.
Unlike spring-blooming alliums, Millenium flowers in midsummer, filling a crucial seasonal gap with rich color and strong vertical interest. The long-lasting blooms attract bees, butterflies, and other pollinators while resisting deer and rabbits—making it as practical as it is eye-catching.
With a compact, upright habit, Millenium is perfect for borders, edging, pollinator gardens, and containers. It thrives in full sun and well-drained soil, and is extremely low-maintenance and drought-tolerant once established.
Add lasting summer color and pollinator appeal to your garden with Millenium Allium—a fuss-free favorite that delivers big garden impact.
