Purple Fountain Grass (Pennisetum setaceum 'Rubrum') is a striking warm-season ornamental grass prized for its rich burgundy foliage and graceful, fountain-like form. Slender leaves emerge upright before arching outward, creating a soft, flowing silhouette. From late summer through fall, long, fluffy purple-pink flower plumes rise above the foliage, gradually aging to warm copper and creamy tones. The feathery, foxtail-like blooms add movement, texture, and seasonal interest to the landscape. Semi-evergreen in mild climates, this colorful grass thrives in full sun and makes an excellent accent for garden borders, mass plantings, modern landscapes, and large patio containers.
