The tall stems of this native perennial cover up in 1" light purple daisies in late summer and fall. Willowleaf Aster, Symphyotrichum praealtum, produces a multitude of upright to arching stems once well-established and makes a grand statement in the fall garden, prairie, meadow, or roadsides. The flowers attract a variety of pollinators but are an especially important late summer and fall nectar source for native bees. Caterpillar host: Field Crescent, Pearl Crescent, Texan Crescent, Roadside Checkerspot, Hoffman's Checkerspot, and American Lady. Willowleaf Aster or Willow Aster is long rhizomatous, versus clumpforming, and will slowly colonize an area once established creating a dense stand at maturity. Provide a full to mostly sunny site in moist to average moist soils. Cutback to ground level after flowering to prevent unwanted seedlings if desired. Item# 10693.
