Solidago canadensis is a herbaceous perennial plant with stems that grow 2-4 feet and sometimes to 6 feet (30–150(–200) cm) tall.

The leaves are 4-6" long and 1" wide. The stems have lines of white hairs, while the undersides of the leaves are pubescent. The leaves are often prominently toothed. The flowers have yellow rays and are arranged into small heads on branched pyramidal-shaped inflorescences, flowering occurs from July to October.
