Annual Flower, Ornamental Grass

Pennisetum setaceum

One of the few annual ornamental grasses, Fountain Grass provides a showy and attractive mound foliage with arching, plumed flowerheads. The flowerheads are lighter than the foliage, providing a unique contrast. Reddish-colored varieties are particularly striking and far superior to the species.
