- Herbs, Native Plants, Perennials, Wildflowers
A low maintenance perennial native to eastern and central North America the blue wood aster is commonly found naturalized in woodlands, meadows, or stream banks. It can be weedy as it self-seeds very easily.
Pinching back the stems will lead to a bushier plant and hopfully avoid the need for staking. The foliage tends to decline by late summer and it can be cut to the ground to avoid any self-seeding and also to help with appearance.
Regions: Mountains, Piedmont, Coastal Plain
Seasons of Interest:
Bloom: Summer- late Fall; Fruit/Seed/Nut: Winter
Wildlife Value: Moderately deer resistant. Host plant for the Pearl Crescent butterfly. Flowers are attractive to bees and butterflies. Songbirds and small mammals eat the seeds. Members of the genus Symphyotrichum support the following specialized bees: Andrena (Callandrena s.l.) asteris, Andrena (Callandrena s.l.) asteroides, Andrena (Cnemidandrena) hirticincta, Andrena (Cnemidandrena) nubecula, Andrena (Callandrena s.l.) placata, Andrena (Callandrena s.l.) simplex, and Colletes simulans.
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. Some susceptibility to powdery mildew, leaf spots, or rust. Aster wilt can also be an occasional problem, if plants are grown in poorly-drained clay soils. Good air circulation helps reduce incidence of foliar diseases. Taller plants may require staking or other support.
This plant may be confused with: Aster cordifolius.
