‘Millenium’ is a compact, clump-forming perennial that grows to about 12 to 18 inches tall and 12 to 18 inches wide. It forms a tidy mound of glossy, grass-like green foliage topped with globe-shaped purple flower clusters.
‘Millenium’ blooms in mid-to-late summer (typically July into August), producing rosy-purple, 2-inch round flower heads on sturdy stems. The blooms are long-lasting, showy, and stand well above the foliage, creating a strong vertical accent in the garden.
‘Millenium’ thrives in full sun and prefers well-drained soils. It’s tolerant of heat, drought, and a wide range of soil types, including clay (as long as drainage is good). This variety is exceptionally well-suited to low-maintenance gardens, borders, and containers.
Yes! Like other ornamental alliums, ‘Millenium’ is deer- and rabbit-resistant due to its mild onion scent. It’s also very low-maintenance—no deadheading is necessary, and it rarely needs dividing. It’s disease- and pest-resistant and thrives with minimal care once established.
Absolutely! ‘Millenium’ is a pollinator magnet, drawing bees, butterflies, and other beneficial insects in droves. Its mid-to-late summer bloom time makes it especially valuable for filling the pollinator gap after spring perennials fade.
