Tall, spreading warm-season perennial grass with noteworthy sharp-edged arching leaves that are coarse, tough, and glossy, growing in height up to 4′. Initially green, the leaves yellow in fall. The spikelets that form the flower spikes in late summer are arranged on one side of the straw-colored flower structure in the manner of a comb, arching and towering over the leaves. Essential host plant for larvae of several moth species including four-lined borer moth, many-lined cordgrass moth, spartina borer moth, and tortricid moths. Also known by the common name Ripgut.

Typical Landscape Use
Can be massed in formal areas, surrounded by lawn or concrete, or used around ponds and in rain gardens. Excellent for wet prairies and erosion control. Will spread where it can.
Establishment and Care Instructions
Can be grown from seed if available. Divide to propagate; for best growth, site in fertile and moist to wet loams though it will grow also in sandy or rocky soils. Spreads readily to form large colonies, less so where soil is drier. Tolerates some shade. When working with the plant, wear protection against sharp leaf edges if necessary.
