Elmleaf goldenrod's stem (and sometimes upper leaf axils) produces an open, airy inflorescence (a panicle) at its tip that may be a foot tall and wide with arching, widely-spreading branches. The flowerheads rest on very short stems (nearly sessile) along one side of the major branches, facing upward; on the opposite side of the branches are small (1") bracts. Both stems and branches in the inflorescence are covered with hairs. The flowerheads are 1/8-1/4" across with 3-6 yellow, pistillate ray florets (no stamens) and 4-7 yellow, perfect disk florets (both stamens and a style). Surrounding the base of the flowerheads are 16-18 bracts (phyllaries) in 2-3 overlapping series.
