Author(L.) Nuttall
DistributionMountains only, but known from just 8 counties so far, with only 5 documented with specimens.

Newf. to MN, south to NC, TN, and MO.
AbundanceRare, only known from a moderate handful of records. This species was formerly tracked as Significantly Rare by the NCNHP, but surprisingly dropped from its tracking completely as not valid, based on Weakley (2020), who inadvertently left this entity out of this publication. The editors suggest a State Rank of [S1S2] and a Significantly Rare status.
HabitatMoist to dry bottomlands, riverbanks, wet meadows, damp fields, and montane seepages.
PhenologyFlowering and fruiting August-October.
IdentificationOur species of flat-topped goldenrods can be told from other goldenrods (genus Solidago) by their generally flat-topped inflorescences and by their slender stem leaves that tend to be all about the same size on a given plant. This species grows 2-3.5 feet tall and has leaves with 3-5 obvious main veins and is the only Euthamia in the NC mountains.
Taxonomic CommentsVar. graminifolia differs only in essentially lacking abundant hairs on upper stems and branches. However, intermediate conditions are too numerous to be comfortable with recognizing both that variety and var. nuttallii.
