How to grow
Very adaptable. Autumn Sun Coneflower prefers moist soil, but will grow in a variety of soil types, including clay, and can tolerate periodic drought and flooding. Plants will be more compact when grown in the sun, but they produce plenty of blooms in part sun. The flowering stems are surprisingly sturdy and usually only require staking during wet growing seasons or if planted in overly fertile soil.
