 Distribution

Newfoundland and Quebec west to MN, south to MD, OH, IN, and in mountains to NC and TN.

Morphology

Upright perennial to 1.5 m from a long, branched caudex. Stems glabrous except in the inflorescence. Leaves of two types; basal leaves oblanceolate to narrowly elliptic, subentire to serrate, tapering to a long petiole that partially sheaths the stem; cauline leaves progressively reduced towards the inflorescence, usually less than 25, the lower ones more than 7 times as long as wide. Inflorescence much longer than broad, the branches straight and mostly not secund except for some shorter ones; inner involucral bracts obtuse or rounded, the outer often acute; rays 1-8, rarely more than 6.

Notes

Flowers August to early October

Wetland indicator: Obligate

Might be mistaken for S. speciosa but the two occur in completely different habitats, and S. uliginosa has much longer lower leaves that do not sheath the stem.
