Members of the genus Pennisetum are exquisite grasses with a timeless style. Most grow in flowing, fountain shapes and many produce lovely, bottlebrush plumes. Others impress with colorful foliage. Tender selections, often red-leaved or variegated, enhance decorative containers and annual color beds. Pennisetum are native to Africa, Asia and other tropical, subtropical and temperate environments worldwide. They thrive in sun, heat and humidity; they require little maintenance.
