Solidago squarrosa, commonly known as stout goldenrod, is a North American species of goldenrod in the family Asteraceae. It is native to Canada (Ontario, Québec, and New Brunswick) and the eastern United States (from Maine west to Indiana and south as far as Tennessee and the Carolinas).[http://bonap.net/MapGallery/County/Solidago%20squarrosa.png Biota of North America Program 2014 county distribution map]

Solidago squarrosa is a perennial herb up to 150 cm (5 feet) tall, with a branching underground caudex. Leaves are egg-shaped, up to 20 cm (8 inches) long near the base of the plant, shorter higher up the stem.
