Pennisetum First Knight

First Knight Ornamental Grass makes a bold vertical accent with broad, sword-like foliage that develops rich burgundy-purple to nearly black color in strong sun. It grows quickly into an upright clump about four to five feet tall, bringing dramatic contrast to sunny beds and large containers. Heat and humidity help it put on its best display through the long South Carolina summer. Available for local pickup from Towns Edge Nursery.
