Giant coneflower is native to eastern Oklahoma, but does well throughout the state.
It is tolerant of moist soils and is quite drought tolerant once established. Giant
coneflower has silvery-blue foliage. Flowers have bright yellow ray flowers that dangle
from a large, upright, dark brown cone on stems that reach 5-6 feet high. Giant coneflower
blooms in early summer but deadheading the spent blossoms will encourage another flush
of blooms in late summer. Plant in masses for best effect. Can be used in mixed borders,
meadows, native gardens, and open woods. This species makes a strong vertical statement
in the landscape.
