Allium 'Millennium'

Allium 'Millennium'


Common Name: Ornamental Onion


A fabulous Allium! Thick, strappy foliage forms a tidy clump while on top masses of 2-inch rose-purple balls of flowers appear in summer. A reliable perennial. No wonder it was the 2018 Perennial of the year!  


Our perennials come nestled in a 4" square CowPot with a free metal plant ID marker. Learn more about why we think CowPots are so awesome here.

  • How To Plant

    CowPots are made from composted cow manure. As the pot decomposes, it feeds the roots of the plant helping it get off to great start. We like to say the perennials think they're delicious and nutritious! :-)

    You will plant the pot along with the plant! No need to put holes in the pot or remove the bottom. It decomposes faster than other non-plastic pot options and the roots easily push through.

    Place the plant in the hole so that the top of the soil in the pot matches the soil line in the garden. Ensure that soil is pressed against the pot on all sides and the bottom. Keep the area inside and outside the pot moist (but not soggy) for 3 to 4 weeks until the plant is established.
