Allium Millenium

Allium x 'Millenium'

Allium Millenium is different than most Ornamenta Onions in that it will form a clump rather than just stay as a single plant. Millenium is more heat resistant than other varieties which makes this a great choice for southern gardeners. If your looking for something a little different in your cut flower arrangements this flowering onion is a good choice for adding a whimsical feel.

Allium Millenium is one of the best flowering ornamental onions available today. This hybrid cultivar flowers in the summer rather than in the spring-like its other ornamental onion relatives. This is a great way to extend the bloom time of alliums in the garden.

Allium millennium blooms in mid-summer and produces large globes of rose-pink flowers. As the plants mature they will have dozens of flowers that will look like pink orbs floating through the garden. Allium Millenium is a clump former so expect the clumps to increase in size year after year. Allium Millenium was voted the 2018 perennial plant of the year by the perennial plant association.
