Heterotheca canescens, commonly known as hoary goldenaster, is a perennial herb that is native to the Great Plains and certain arid regions of the central United States and northern Mexico, particularly thriving in prairies, open fields, and along roadsides. It is often found in disturbed habitats, which include areas that have been altered by human activity or natural processes. This plant typically grows to a height of 1 to 3 feet (0.3 to 0.9 meters) and spreads to a similar width. Hoary goldenaster has a bushy form with narrow, hairy leaves that contribute to its common name. From late summer to fall, it produces clusters of small, daisy-like yellow flowers that are quite showy and attract pollinators such as bees and butterflies.

In cultivation, hoary goldenaster is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and naturalistic plantings. Its bright yellow flowers add color to the garden when many other plants have finished blooming. It is often used in wildflower gardens, as a border plant, or in restoration projects. Hoary goldenaster prefers full sun but can tolerate light shade and requires well-drained soil. It is generally low-maintenance, but it can spread somewhat aggressively in favorable conditions. There are no major disease or pest problems associated with this plant, although it may require some control to prevent unwanted spread.CC BY-SA 4.0
