The native Arrow-Leaved Aster is common in our area. It prefers partial sun and slightly moist to dry soil with loam, clay-loam, or rocky-loam. Habitats include upland woodlands, rocky woodlands, wooded slopes, thinly wooded bluffs, woodland edges and edges of yards. This perennial has a smooth stem, 2-4' tall, with alternate, toothed, arrow-shaped, wing-stemmed leaves up to 4" long and 2.5" wide. The stem's terminal cluster of flowers have blooms that are about ½" across with 8-15 pale blue petals surrounding 8-12 disk flowers (florets) that are yellow later turning reddish purple.
