Allium ‘Millenium’


Ornamental Onion

USDA Zone: 5-9

Plant number: 1.032.070


A truly impressive hybrid Ornamental Onion from Mark McDonough considered to be the best available in years. Compact upright clump of glossy, thick, green leaves with 5cm (2") rose-purple ball clusters appearing just above the foliage on strong stems in mid to late summer. Easy to grow. Leaves have a slight onion smell when crushed. Flowers are attractive to butterflies. This looks best when combined with a bushy, low-growing perennial to hide the withering onion leaves at blooming time; hardy Cranesbill Geraniums are an excellent companion. The fleshy bulbs may be lifted and divided after several years, best done after the leaves wither. Chosen as the 2018 Perennial Plant of the Year by The Perennial Plant Association.
