Solidago ptarmicoides is distinctive within the genus in having white to cream-colored flowers, in heads arranged in a flat-topped corymb rather than in an elongated raceme. One plant can sometimes produce as many as 50 small heads. Leaves are narrow and linear, often rather stiff. The species prefers dry, sandy soils and grassy meadows.
