Purple Fountain Grass (Pennisetum x advena 'Rubrum') is a warm weather beauty with unmistakable burgundy-red foliage. Pastel pink flower heads emerge in summer and last for a long season, well into autumn. Purple Fountain Grass has become a sought after perennial for its reliable color that looks great in beds and borders, or standing alone in your favorite container. Gardeners in cooler climates need not despair. This pretty ornamental grass makes a fantastic annual, whose consistent purple foliage stands out when nearby blooms begin to fade.
