'Millenium' Ornamental Onion blooms in July and August, producing lots of 2" purplish lavender round clusters of flowers like drumsticks on 15" stems. The onion scented leaves are glossy and strap-like, making a thick clump from which the long lasting blooms arise. Many insects and butterflies feed off them but deer and rabbits will not touch them. All Ornamental Onions do well under Black Walnuts. Allium 'Millenium' is the product of Mark McDonough's hard work with Ornamental Onions. 2018 Perennial Plant of the Year.
PRN Preferred: A long blooming selection with clean foliage, simply stunning in bloom.
