Millenium Ornamental Onion is a beautiful, herbaceous, bulbous, perennial. Ornamental Onion is popular for its spectacular flowers, which are large, ball shaped, and a lilac purple colour. It is a hybrid ornamental onion developed by allium breeder Mark McDonough.

These flowers look glorious when mass planted as a border or foundation. The plant appears from its bulb in a clump of leaves that are erect, sword shaped, and dark, glossy green. All parts of this plant have an oniony fragrance, as it belongs to the Allium genus, which make it great for deterring wildlife, like rabbits and deer. The flowers are beneficial to pollinator species, like bees and butterflies. The flowers are also excellent for long lasting cut flowers.

This perennial grows well in full sun and moist, but well drained soil, like sandy loam. It is fairly drought tolerant and can be considered for xeriscaping.
