| Distribution | Scattered in the Mountains; not present downstate.
N.B. to Ont., south to western NC, IN, and KY. | |
| Abundance | Very rare and declining. Very few recent records, with the NCNHP listing only two extant records, of only a few plants at each site. In danger of extirpation, presuming that it is not being overlooked. This is a Significantly Rare species. Weakley (2022) records it as Historical. | |
| Habitat | Dry to mesic rocky montane woodlands, forest openings, and rocky slopes -- but generally in rich, rocky soil under a canopy. | |
| Phenology | Flowering and fruiting August-September. | |
| Identification | Stout Goldenrod grows up to 4.5 feet tall, the stem glabrous, and the inflorescence branches short-hairy. Basal and lower stem leaves are elliptic to ovate, up to 8 inches long, taper to long, winged stalks, and are toothed on the margins. The stem leaves are much smaller, lack stalks, and vary from lance shape to ovate and not toothed. The inflorescence is cylindrical or narrowly elliptical, the numerous showy heads oriented facing sideways (parallel to the ground). Hardly any living botanists have seen this rarity in the state, but it should be obvious when found -- by its tall stature, large lower leaves, and long and narrow terminal spike, but with the large heads not densely packed along the axis. | |
