Allium 'Millenium'

Description

'Millenium' is a hybrid ornamental in the onion family (Amaryllidaceae) bred by Mark McDonough. The parentage is unknown.

It grows 1 to 1.5 feet tall in full sun to partial shade in dry to medium moist, well-drained soil. Plant bulbs in the fall and deadhead spent flowers to prevent unwanted self-seeding, although this particular allium doesn't reseed too readily. Divide bulbs as needed in spring or fall.

Flowers appear in mid to late summer on 18 to 20-inch sturdy stems. The long-lasting rosy purple florets appear in round umbels up to 2 inches across. The narrow upright leaves and flowers have an onion-like odor but are not edible. It was selected as the 2018 Perennial Plant of the Year® by the Perennial Plant Association.

Use this Allium in borders or groups of cutting or cottage gardens.

Insects, Diseases, and Other Plant Problems: -   Bulb rot can occur in poorly drained soils. Watch for thirps. Watch for  mildew, rust and leaf spots.
