Smooth Aster (Symphyotrichum laeve)

$5.00

Such a pretty late bloomer that the native bees love. It attracts many native bees, butterflies, and moths along with many other insects. It is the host plant to the Pearl Crescent and 43 other species of butterflies and moths in our area (illnoiswildflower.info). It is also listed as a preferred pollinator plant by the Xerces Society (Xerces.org). Smooth Aster also has 36 specialist bees that use it as a host plant (Holm, 2017) (Johnson and Colla, 2023)! If you are lucky, this plant will spread slowly by non-aggressive rhizomes.
