Plume Grass (Saccharum ravennae), also called ravenna grass, is a towering ornamental perennial that commands attention in any garden. Hardy in zones 5 through 9, this dramatic grass grows 6 to 12 feet tall and spreads 4 to 6 feet wide, forming impressive clumps of narrow, gray-green foliage. From late summer into fall, it produces its signature feature: stunning plumes that emerge purplish-bronze and fade to silver-gray, persisting well into winter on stiff stalks that rise well above the leaves. This grass tolerates drought and urban conditions with ease, making it both beautiful and practical for challenging sites.

The plumes are the real showstopper, reaching up to 24 inches long and shifting from purplish-bronze to luminous silver-gray as the season progresses. Unlike tender pampas grass, this variety survives cold winters in zone 5, yet it still delivers that dramatic, tropical-looking presence that makes it a standout in late-season gardens. It thrives on neglect once established, handling drought and poor urban soils without complaint, and its tall, architectural form creates stunning silhouettes against fall and winter skies.
Plume Grass serves as a focal point in ornamental landscapes and mixed perennial borders. Its height and dramatic form work well as a tall background element, and the long-lasting plumes provide late-season color and texture when many other plants have faded. The silvery plumes persist through winter, offering architectural interest and movement in the garden during the coldest months.

Cut Plume Grass to the ground in late winter to early spring, removing all dead foliage before new growth begins. Avoid cutting in fall, as the winter plumes provide ornamental interest and can persist into the new year. If self-seeding becomes a problem, deadhead spent flower plumes during the growing season.
