Symphyotrichum eatonii (formerly Aster eatonii) is a species of aster known by the common name Eaton's aster.[3] It is native to much of western North America from British Columbia to Saskatchewan, the Sierra Nevada in California , the Rocky Mountains region, to Arizona and New Mexico, where it grows in many habitats, especially wet areas such as meadows and near ditches.[4]
Description
Symphyotrichum eatonii is a perennial herb growing 40–100 centimeters (1 foot 4 inches–3 feet 3 inches) from a short rhizome. The thin leaves are up to 20 centimeters (8 inches) long, lance-shaped, and pointed at the tips. Some of the leaves and the upper parts of the stem are hairy.[4]
The inflorescence holds several flower heads containing many white to pink ray florets around a center of yellow disk florets. The fruit is a hairy cypsela that resembles an achene.[4]
Taxonomy
Symphyotrichum eatonii is classified in the subgenus Symphyotrichum, section Occidentales.[4] (As of June 2021) Catalogue of Life, Flora of North America, and Jepson eFlora accepted this species as Symphyotrichum bracteolatum,[5][4][6] while POWO, NatureServe, and Canadian botanist John C. Semple circumscribed to S. eatonii.[2][1][7]
