This herbaceous perennial grows 4 to 8 feet tall with yellow, daisy-like flowers on slender, erect stems from late summer into fall. It thrives in full or part sun and poor, sandy, or rocky soils with good drainage. Plants grown in dry soils tend to be shorter, open, and somewhat spindly, while those grown in soils with consistent medium moisture tend to be taller and fuller. Overly moist soils tend to cause the stems to sprawl. It self-seeds freely and forms large colonies in optimum growing conditions. It holds its own with big bluestem and Indian grass. Birds visit for seeds, and pollinators include small native solitary bees and small butterflies. 
 
Native habitats include prairies, dry open woods and wood margins, and roadsides and railroad tracks.
