Eurybia divaricata, commonly known as the White Wood Aster, is a herbaceous perennial native to rich, mesic deciduous forests and forest edges in eastern North America, particularly in the Appalachian region. It is also found in a few locations in southeastern Canada, notably in Ontario and Quebec, where it is considered threatened. This species thrives in the dappled sunlight of open woodlands and along the margins of forest clearings, often forming dense colonies.

The White Wood Aster typically grows between 30 and 90 cm tall, with a bushy habit and arching, zigzag stems that give it a distinctive appearance. Its flower heads, which bloom from late summer to fall, feature bright yellow centers surrounded by white rays, creating a striking contrast against the dark green, heart-shaped, and sharply toothed leaves. The flowers are arranged in flat-topped clusters, adding to the plant’s ornamental value. Gardeners appreciate the White Wood Aster for its adaptability, drought tolerance, and the late-season burst of blooms it provides when many other flowers have faded. It is often used in shade gardens, woodland plantings, and naturalized areas. For optimal growth, it prefers partial to full shade, consistent moisture, and well-drained soil, though it can tolerate a range of conditions. While generally low-maintenance, it can be susceptible to powdery mildew in humid conditions.CC BY-SA 4.0
