Allium 'Millenium' - ORNAMENTAL ONION 'MILLENIUM'

A superb late flowering show-stopper, this tough plant has no problems with pests and diseases. Deer and rabbit resistant and highly attractive for butterflies and bees. Perennial Plant of The Year in 2018.

It's no wonder why we see this amazing plant in more and more public spaces - it's one of the plants that does very well in Midwest conditions and isn't bothered by the heat, summer droughts, clay soil or overpopulated deer. Dense mounds of glossy leaves stay ornamental for the whole season, and the 2" rose-purple globes appear in mid to late summer and last for 4 weeks.

'Millenium' is not as sterile as its cousin 'Summer Beauty", but it is not as prolific of a seeder as other alliums. If you want to avoid seedlings, deadhead before the seeds get ripe. Looks great in smaller groups, as well as single clumps when they repeat in the flower bed. Can be used as a groundcover, even when it's not fast grower.
