Symphyotrichum eatonii forms tall, narrow clusters of white-petaled flowers supported by leafy bracts. Flower heads are quite large, up to 2 inches across, and consist of 20 to 40 ray florets (usually white; less often pale pink) around 35 to 60 disc florets, which are bright yellow at first but become purplish (and elongated) when mature. The green involucral bracts are triangular, point outwards, and have differing lengths. The rigid stems are reddish towards the base and bear many long thin leaves; when flowering these are mostly around the middle and upper parts of he stem, as those near the base wither early in the season.
