Prairie Onion (Allium stellatum) is an uncommon bulb-forming wildflower native to the Great Plains and Midwest. Showy globes of lavender-pink flowers appear in mid-summer and are highly attractive to pollinating insects like native bees, honeybees, and butterflies. Suitable for challenging sites, including dry, sandy, and rocky sites. The plants are uneaten by rabbits and deer, and will naturalize and multiply by reseed in the garden.

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).
