DistributionThroughout the state, except nearly absent from the outer Coastal Plain.

N.S. to Sask. and MT, south to northern FL, TX, and CO.
AbundanceCommon across the state, other than the outer Coastal Plain, where rare and local. Can be locally abundant, but not nearly as abundant as is the similar-looking Tall Goldenrod (S. altissima).
HabitatMoist to wet meadows, margins of freshwater marshes, streamhead ecotones, bottomlands and their edges, swamp openings, roadside ditches. Sometimes found in less wet sites, such as fields -- but generally considered a wetland species.
PhenologyFlowering and fruiting August - early October.
IdentificationGiant Goldenrod is among our tallest species, typically 3-6 feet but as much as 7 feet. Stems are very leafy, the leaves lance-shape, tapered to a point, and toothed on the margins. The stems are smooth and glaucescent, white to flesh-pink. The inflorescence is typically triangular in outline and tapers to a point; branches are usually curved. It closely resembles Tall Goldenrod, and may be found together, but that species has hairy stems, and leaves are very short-hairy beneath and rough above; that species usually grows in drier and more upland sites.
