Rich deep maroon flower heads have a delicious chocolate scent when the flowers are rubbed! Blooms in late summer. The flowers look elegant when planted with gray foliage plants and yellow blooms. In colder climates dig the tubers out at the end of the season, like dahlias. Give this plant well drained soil to promote vigorous growth and assure that plants will come back after winter.
