It can also be found in meadows, dry pine forests, open forests, and pastures. It grows .5 to 2 feet tall with basal downy leaves and flowers that occur May to August. The yellow-orange ray flowers surround the yellow disc florets are followed by achenes. The flowers form as a solitary bloom at the top of each stem. In windy locations, they may need to be staked for additional support. Cutting the stem back before the plant flowers will keep the stems short, as well as produce a secondary bloom.
