Rice Cutgrass
Leersia oryzoides
Rice Cutgrass is a perennial grass that typically grows in dense clumps along the margins of water bodies such as streams, ponds, and marshes. It reaches heights of 2 to 4 feet and, during late summer to early fall, produces small, greenish flower spikes that are often hidden among the leaves. These flowers are wind-pollinated and not showy, but they produce seeds that are an important food source for waterfowl and other wetland birds. Rice cutgrass is highly valued for its ability to stabilize soil and provide cover for aquatic and semi-aquatic wildlife.

Maintenance Tips
- Naturally adapted to wet conditions; ensure the soil remains consistently saturated or shallowly flooded.
- Generally requires little maintenance. Can be cut back in late winter to manage growth and remove old foliage. Take care with its sharp-edge foliage if you plan on pruning heavily.
- Prefers muddy, wet soils; ideal for naturalizing in riparian or wetland areas.
- Mulching is typically not necessary due to its aquatic or semi-aquatic environment.
- Monitor for signs of stress or overcrowding, which may require thinning or division to maintain plant health.
