Allium Millenium is a hardy, long-blooming ornamental onion prized for its globe-shaped clusters of vibrant purple-pink flowers that appear July through September. Its sturdy, upright stems rise above neat mounds of glossy green foliage, providing structure and color long after many perennials have faded. We love Millenium because it’s an easy-care choice for front of the border or container plantings as it reaches no more than two feet tall. It is a great addition to pollinator gardens as well, as it joyfully attracts bees.
