Leaves basal and cauline; basal leaves to 40 x 7.5 cm, the blades narrowly elliptic-acuminate, more or less serrate, tapering to a long petiole; basal and lower leaves often more than 2.5 cm wide, present at flowering time, 1-nerved or faintly 3-nerved. Flowers yellow; heads crowded in a paniculiform inflorescence mostly about as broad as long; inflorescence branches recurved-secund; involucres 3-5 mm; rays 7-12, minute; disk flowers 9-14; achenes short-hairy.

Wetland indicator: Upland

Begins blooming a little earlier than most other goldenrods. Note that the cauline leaves are not always serrate as in the pictures here but can be entire as well.
