Allium 'Millenium' is a ornamental perennial bulb. A tough, long-lived ornamental allium with rich, rosy-purple globe-shaped flowers in mid to late summer. Unusually long bloom time, excellent heat tolerance, and reliable non-seeding habit. Plant in full sun in well-drained soil. Drought tolerant once established. Allow foliage to die back naturally after flowering. A striking addition to perennial borders, rock gardens, and pollinator gardens — globe-shaped blooms are exceptional as fresh or dried cut flowers.
