Allium 'Cobalt Millenium' is a compact ornamental onion, growing 14-22 inches tall and wide with dense, clumping blue-green foliage. In mid-to-late summer, it produces large, rosy-pink, globe-shaped flowers that attract bees, butterflies, and other pollinators. This low-maintenance perennial is deer- and rabbit-resistant, drought-tolerant once established, and an excellent choice for borders, rock gardens, and pollinator-friendly landscapes.
