Green-Head Coneflower is a perennial that grows 3 to 10 feet tall with a open, lanky appearance. This plant prefers moist soil, but grows well in average, medium, well-drained soil in full sun to part shade. It is often found in woods, meadows, streambanks, and roadside ditches. The plant tolerates hot, humid summers, but can spread aggressively by underground rhizomes.
If using in a smaller garden divide clumps and deadhead old flowers to encourage rebloom. Green-Head Coneflower has 2 to 4 inch yellow flowers from late summer into the fall.
