Allium Millenium

Create a spectacular mid-summer display with Millenium Ornamental Onion, a low-maintenance perennial that produces bold balls of lilac-purple flowers on tall stalks in mid-summer. Growing 12 inches tall with flower stalks reaching 20 inches, this variety features glossy, thick, dark green foliage that forms an upright clump. Deer-resistant and attractive to butterflies, it makes excellent long-lasting cut flowers. Plant in masses for the best effect in borders or containers. The foliage goes dormant in summer, so interplant with late-season bloomers.
