Ornamental Onion
Allium 'Millenium'
Rose-purple ball clusters appear just above the foliage on strong stems.
Perennial of the Year 2018
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.
2 inch flower diameter.
