Symphyotrichum firmum, commonly known as Shining Aster or Shiny-leaved Aster, is a perennial herb that is native to North America, specifically thriving in moist meadows, wet prairies, marsh edges, and along stream banks in Canada and the northern United States. It can reach up to 7 feet tall and is characterized by its stout, hairy stems and lanceolate leaves with a glossy appearance. The plant produces an abundance of flowers from late summer into fall (August to October), featuring white to pale blue or lavender ray florets surrounding yellow to pink disc florets, which are quite showy and attract a variety of pollinators.

Shining Aster is valued for its late-season blooms and its ability to support wildlife, particularly bees. It is used in naturalistic plantings, such as rain gardens and wildlife habitats, and can be an attractive addition to borders in gardens that aim to provide ecological benefits. This aster prefers full sun to part shade and requires moist to wet soil conditions with good drainage. While it is not particularly drought-tolerant, it can withstand occasional flooding. Gardeners should be aware that in optimal conditions, it may spread vigorously, potentially becoming aggressive in smaller garden settings.CC BY-SA 4.0
