This is a tough tall plant from the tall grass prairie, and can reach 8' high under garden conditions. The strong winged stems never lodge and remain erect through the winter.

The small yellow daisy flower heads come in August to October in large terminal clusters. The ray flowers sometimes fail to develop, and this perennial has been criticized as not having enough flower power for the mixed border. Piet Oudolf admires it for the meadow garden.

This species may self-sow.

Its foliage is bitter, so deer and rabbits don't feed on it, but there are some beneficial insects that do and not badly. The flowers are good for pollinating insects and the seed is eaten by birds.
