Pennisetum setaceum 'Rubrum' (Purple Fountain Grass) is a stunning, fast-growing ornamental grass that brings instant texture, rich color, and graceful movement to a landscape. It grows in a clean, dense clump of arching, purplish-maroon blades that mimic a splashing water fountain. From mid-summer through autumn, it is topped with soft, feathery, copper-pink flower plumes, and it is a massive favorite for mixed patio planters, poolside beds, modern rock gardens, or planted in repeating rows as a soft, temporary privacy screen.
