Distinguishable from other asters by its larger compound flowers (up to 1.5 inches). Flowers vary from pink to purple and have golden centers. Leaves are 4 to 5 inches long, very hairy, lance-oblong in shape, and have mostly smooth margins. Leaves clasp the stem, nearly encircling it. Often appears messy by the fall due to drought, insects, and disease. Tall plants may need staking. Attracts bees and butterflies. Important food source for migrating monarchs. Host plant for the pearl crescent and checkerspot butterflies. Resistant to deer browse.
