'Millenium'
Allium
Allium 'Millenium' is a compact, clump-forming perennial named the 2018 Perennial Plant of the Year. It produces globe-shaped rosy-purple flowers that bloom in mid to late summer, lasting for weeks. The flower clusters measure about 2 inches across and rise on sturdy stems, reaching 15 to 20 inches tall. Its deep green, grass-like foliage remains attractive throughout the season. Thriving in full sun, it prefers well-drained soil and is highly drought-tolerant once established. Resistant to deer and rabbits, it attracts pollinators and provides reliable seasonal color in USDA zones 4-9.
