Rough-leaved Rice Grass

Oryzopsis asperifolia

Rough-leaved Rice Grass is a cool-season perennial grass that grows 1-2 feet tall and is often found in shaded forests, along trails, and in woodland edges. Its narrow leaves have a rough texture, and it produces delicate, airy seed heads in late spring to summer. This grass provides food and habitat for wildlife and is valued for erosion control in shaded areas where other grasses struggle to grow.

Sowing Information

Sow seed onto a firm, weed-free seedbed. Hand-broadcast seed making two perpendicular passes for even coverage. If planting a mix, broadcast the grass component first and lightly rake/drag it into the top 1/8–1/4" of soil. Next, broadcast wildflower/forb seed and press it into the soil surface (with a roller/cultipacker or the back of a rake) to ensure good seed-to-soil contact. After seeding, apply a very light layer of clean, seed-free straw (or other weed-free, site-appropriate mulch) to reduce erosion and retain moisture without smothering seedlings. A good rainfall or thorough watering will help settle seed and mulch and improve germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
