Symphyotrichum cordifolium, commonly known as the Blue Wood Aster or Heartleaf Aster, is a perennial herb that is native to rich deciduous woods, meadows, and thickets throughout central and eastern North America. It typically grows up to 4 feet tall and can spread widely. This species is characterized by its heart-shaped leaves and clusters of small, bluish to lavender daisy-like flowers with yellow centers that bloom from late summer to fall, providing a late-season nectar source for pollinators.

Blue Wood Aster is valued for its ability to thrive in a variety of conditions, including part shade and dry to medium moisture soils. It is an excellent choice for naturalized areas, woodland gardens, and borders, where its late-season blooms can offer a splash of color when many other plants have finished flowering. It is relatively low maintenance and can be propagated by division in spring or fall. While it can spread via rhizomes, it is not typically aggressive. However, it can be susceptible to powdery mildew in humid conditions.CC BY-SA 4.0
