Hardy Pampas Grass

Erianthus ravennae

One of the loveliest ornamental grasses, superb as an architectural specimen or large accent. Foliage has a clumping habit; plant in groups to create a screen or windbreak. Long, showy, silvery white, silky plumes have gorgeous autumn coloring, persist into winter, and are superb in fresh or dried floral arrangements.
There are very few rules in gardening, but perhaps the most important one is to work within your zone. Choosing plants that grow and thrive in your particular climate is the very first step toward having a beautiful garden . Learn More

Design IdeasUse this hardy grass where it's too cold for true Pampas Grass. It is a stunning addition to the garden, either planted as a specimen or in a group for the larger garden. Plant in well-draining soil, as excessive moisture or fertility will will stunt growth or cause the canes to fall over. Consider as a background specimen in a cutting garden; the handsome plumes are striking in floral displays, either fresh or dried.
