And the 2018 Perennial of the Year goes to… 

BLOOMINGTON, Ill. – Allium ‘Millenium’ has been awarded the 2018 perennial plant of the year.

University of Illinois Extension horticulture educator, Kelly Allsup, just heard about this plant at a pollinator conference in this fall from Steve Foltz, Director of Horticulture at the Cincinnati Zoo and Botanical Garden, calling it a must-have plant for the pollinator garden. The zoo has placed it on their Zoo’s Best Perennials for Pollinators list where they promote plants throughout the zoo so that homeowners know what to plant in their own yards. The program involves teen volunteers known as the Buzz Troop who use cameras to track pollinators to different flowering plants.

 “This cultivar of flowering onion is a result of breeding Allium nutans and Allium lusitanicum and was selected for late flowering masses of rose-purple blooms, uniform habit and neat shiny green foliage that remains attractive all season long” states University of Illinois Extension horticulture educator, Martha Smith.

Allium “Millenium” is full sun perennial with leaves growing a foot tall with multiple spherical umbels of florets 18-20 inches tall that last about a month. Another attribute making it an outstanding plant is its drought and heat tolerance. However, in hot summers it may benefit from afternoon shade, but requires at least six hours of sun.

Allium ‘Millenium’ is a bulb on a horizontally spreading rhizomatous stem that clump and gardeners have the option to divide every three to four years after the foliage dies. Alliums are planted in the fall, before the ground freezes, along with other flowering bulbs like tulip and daffodils. Unlike giant alliums that grow, three to

four feet tall, these Millenium alliums stay compact and are more floriferous. They also have sterile seeds and therefore do not spread like garlic chives. Flowering onions, in general, are not dug up by voles or squirrels and not browsed by deer.

Perennial plants of the year must be standouts amongst their competitors. Generally, they must be sustainable for a wide range of climate conditions, have low maintenance requirements, be relatively disease and pest free, and have multiple seasons of interest. Allium ‘Millenium’ fits all the requirements and is a must-have for the perennial garden.For more information on this story or additional Extension programming, please contact us at the McLean County Extension Office at (309) 663-8306 or visit go.illinois.edu/LMW
