Prairie Onion (Allium stellatum)
Easily grown in average, dry to medium, well-drained soil in full sun to light shade. Best in full sun, but appreciates some light afternoon shade in hot summer climates. Best in rocky or sandy soils. Plants will naturalize by self-seeding and bulb offsets in optimum growing conditions. Deadhead flowers before seed set to help control any unwanted spread. Foliage persists to the time of or slightly past flowering in summer before dying back. Plants are easily grown from seed which should be planted in spring or from bulbs/bulb offsets which should be planted in autumn.
