Red Hook Sedge
Ornamental grasses and grasslike plants
Grassy perennial from the mountains of New Zealand. Stiff, narrow, slightly arching leaves form a tuft 8–15 in. tall and wide. Foliage is rich, dark mahogany to bronze green; lovely when backlit. Black, sharply pointed seed heads are produced in summer. Good choice for containers, ponds, or stream edges. Reseeds a bit, but not enough to be a problem. Dislikes intense heat; mulch to keep roots cool.
Leaves have creamy white edges.
