Millenium Ornamental Onion (Allium 'Millenium') is among the best of the ornamental onions. This award-winning perennial produces a compact clump of glossy green leaves. Bright rosy purple, rounded flower clusters appear on strong stems just above the foliage. Unlike spring-blooming Allium bulbs, 'Millenium' blooms in mid-summer. The attractive, shiny deep-green grassy foliage is very ornamental and lasts all season including winter interest in Kansas. Grow in just about any soil including heavy clay in full to part sun. In Eastern Kansas, typically our 40 inches of rainfall is sufficient without extra water. And as with all alliums, these are completely rabbit proof. Considered a "Once it's there, it's there forever" plant!
