Heart-Leaved Aster (Symphyotrichum cordifolium)

$5.00

Heart-leaved Aster is a great late-season source of food for pollinators and migrating butterflies. The flowers attract a ton of native bees including 36 different kinds of specialist bees (Johnson and Colla, 2023) and it is the host plant for the Pearl Crescent and 12 other species of butterflies and moths in our area (nwf.org)(illinoiswildflower.info). Heart-leaved Aster is quite adaptable but grows best in partial shade, however, it will tolerate nearly full shade and nearly full sun.
