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]
