Allium 'Gladiator'

Allium 'Gladiator'


Common Name: Ornamental Onion


FALL 2021 SHIPPING. Perhaps one of the most recognizable and beloved alliums, Gladiator stands 48" tall with enormous 6" balls of purple. Mass them together or pair them with soft mounds of grass, they look marvelous! Easily naturalizes for more blooms year after year.


Note: Our Gladiators come already rooted vs. as a bare bulb. It's best when planted in early spring (before they get too tall) or in the fall (after they have gone dormant).


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 a 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 all 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.
