Ideal for shadier areas, Short's aster produces blue-violet flowers in the fall--blooming for about a month--that are a good resource for bees, butterflies, and other pollinators. Host plant to the Silvery Checkerspot and the Pearl Crescent butterflies, and several moths. Like many asters, it has a tendency to flop over later in the season from the weight of the flowers. Dry-mesic to mesic soil. 2-3'.
