Summary

Solidago ptarmicoides, commonly known as Prairie Goldenrod or Upland White Aster, is a deciduous perennial herb native to dry prairies, open woodlands, and rocky outcrops in the Central and Eastern United States and Canada. It typically grows to a height of 1-3 feet (30-90 cm) with a similar spread. The plant is unique within its genus, featuring white to cream-colored flowers in flat-topped clusters (corymbs) rather than the elongated racemes typical of goldenrods. Each plant can produce up to 50 small flower heads, blooming from late summer to early fall. The leaves are narrow, linear, and often stiff, adding to its distinctive appearance.

Prairie Goldenrod is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and naturalized areas. Its unique flower color among goldenrods makes it a striking addition to wildflower gardens, borders, and meadow plantings. It attracts pollinators such as bees and butterflies, contributing to the biodiversity of garden ecosystems. While it prefers full sun, it can tolerate light shade and is adaptable to a range of soil conditions, provided they have good drainage. It is not commonly afflicted by serious pests or diseases, but powdery mildew can occasionally be a problem in humid conditions.CC BY-SA 4.0
