Combining interesting flower shapes creates a garden design with texture and depth. Its globe-shaped, rosy-purple flowers add a perky, colorful focus to your late summer garden. Mature plants are covered in dozens of long lasting flowers. Foliage is glossy deep green, grass-like and heat tolerant. You will love this low maintenance dependable garden workhorse and pollinators will too! Unlike many Ornamental Alliums, this hybrid is clump-forming and seeding is much less an issue. Bred by horticulture researcher Mark McDonough of Massachusetts. Thank you, Mark!

Allium 'Millenium'

Allium General Information

Alliums as a genus are easy-to-grow and come in a palette of colors, heights, flower shapes and bloom times. They provide long-lasting flowers ideal for bouquets and are sunny summer performers. Flowers dry to tan, and have remained upright all winter here in NE Ohio. A. Millenium is not used for culinary purposes. *Please note: We are not permitted to ship Alliums to Idaho or the Washington counties of Adams, Benton, Franklin, Grant or Klickitat.

Allium Plant Care

Clumps may be lifted and divided in either spring or fall. Allium will tolerate most soils, but performs best in sandy soils. Add organic matter like compost to clay soils if needed to improve drainage and lighten the soil.

All potted plant material is restricted from shipping to Idaho

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

100% Guarantee

We offer a 100% guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!

Shipping Details
