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).
Prairie Onion (Allium stellatum) is grown for its showy mid-summer
flowers. Similar to the rare Nodding Wild Onion (Allium cernuum), this plant is
a great choice for gardeners bothered by browsing deer and rabbits, as the
plants are onion-scented and not eaten. Easily grown in most soil types, the
plant is a good naturalizing species re-seeding itself among other garden
plants. Recommended companions include Blazing Star (Liatris), Purple
Coneflower (Echinacea) and native grasses like Sideoats Grama Grass (Bouteloua
curtipendula).

Planting and Growing Allium (Ornamental Onion) Plants
Allium (Ornamental Onion) is a large genus of culinary and ornamental plants with deep green folliage and excellent deer and rabbit resistance.
Bulb types are late spring/early summer bloomers that go summer dormant.
Late summer/early fall bloomers (like 'Millennium') are not bulbous and grow actively over the spring and summer months.
Plant in most any type of soil including clay, with full to part sun. Mulch with common mulch materials, such as bark, pine needles or gravel.
Allium prefers dry to moderate soil moisture once established.
Cut bulb-types to ground level when foliage begins to turn yellow in summer. Cut non-bulb types to the ground in fall.
Fertilize lightly in fall with Yum Yum Mix/compost blend.
