Allium Millenium is one of the very best ornamental onions. Unlike spring-blooming Allium bulbs, this hybrid Allium blooms in mid-summer with large globes of rose-pink flowers. Mature plants have dozens of globes covering this perennial plant. Attractive, shiny deep-green grassy foliage is very ornamental. Perennial Plant Association 2018 Plant of The Year.

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Details
Allium Millenium (Millenium Ornamental Onion) provides lots of gorgeous, butterfly-attracting flowers in late summer when the garden is most in need of color. We have come to adore this Allium for its numerous virtues: attractive, shiny deep green foliage, profuse display of bright rose-pink flowered globes, vigorous growth rate, and excellent deer and rabbit resistance. Best of all Allium 'Millenium' is a foolproof companion plant that looks great with many other summer blooming perennials. This superb allium hybrid is difficult to find in the trade. It was originally selected in 2000 by Allium maven Mark McDonough. 15" tall x 18-22" wide (Propagated by division). This Allium is shipped as a pot, not as a bulb and differs from commonly found Allium in that it blooms in late summer, instead of spring.

Planting and Growing Allium (Ornamental Onion) Plants

Allium (Ornamental Onion) is a large genus of culinary and ornamental plants with deep green folliage and excellent deer and rabbit resistance.

  • Bulb types are late spring/early summer bloomers that go summer dormant.
  • Late summer/early fall bloomers (like 'Millennium') are not bulbous and grow actively over the spring and summer months.
  • Plant in most any type of soil including clay, with full to part sun. Mulch with common mulch materials, such as bark, pine needles or gravel.
  • Allium prefers dry to moderate soil moisture once established.
  • Cut bulb-types to ground level when foliage begins to turn yellow in summer. Cut non-bulb types to the ground in fall.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.
