ALLIUM 'Millenium'

Image of Allium 'Millenium'

James Burghardt

Family

Liliaceae

Botanical Name

ALLIUM 'Millenium'

Plant Common Name

Millenium Ornamental Onion, Ornamental Onion

General Description

Bred by ornamental onion expert Mark McDonough, this excellent and unique allium hybrid peps up the late summer garden with a profusion of spherical, pastel purple, drumstick-like flowerheads. The softly-colored blossoms can decorate the garden for up to a month, and are borne on slender stems which rise from dense, compact clumps of slender, glossy, deep green foliage.

Grow this perennial in full to part sun and well-drained soil of average moisture and fertility. The late-flowering habit of ‘Millenium’ makes it a great choice for breathing life into tired beds and borders at summer’s end.
