Solidago canadensis L. is a native rhizomatous perennial which is characteristic of abandoned farmland, infrequently grazed pasture, waste areas, and tall-grass prairies in North America. Original research and information from other studies are incorporated into a summary of the biology of this species complex. The review uses the taxonomic treatment of Scoggan (The Flora of Canada 1979) wherein S. canadensis L. includes several taxa which are frequently granted species status, including S. altissima L., S. lepida DC. (sensu Fernald), S. gilvocanescens (Rydb.) Smyth, S. scabra Muhl., S. elongata Nutt., S. salebrosa (Piper) Rydb., and S. pruinosa Greene.
