Notes
Prairie onion (Allium stellatum) is a bulb for borders, meadows, and naturalized areas. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes full sun to part shade and dry to moist, sandy or loamy soil. Deer tend to pass it by. Round balls of rose-pink to lavender flowers rise above chive-like leaves that die back as the flowers emerge.
Pairs well with Brown-eyed Susan, Aromatic aster, and Sedge.
