Solidago squarrosa, commonly known as stout goldenrod , is a North American species of goldenrod in the sunflower family. 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).
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 farther up the stem. One plant can produce as many as 200 small yellow flower heads in a narrow, elongate array at the top of the plant.
