Elymus trachycaulus

Common Name: Slender Wheatgrass

Slender Wheatgrass is a cool-season, clump-forming grass that grows 1 to 5 feet tall, producing narrow, upright seed heads from midsummer to fall. It is commonly found in prairies, savannas, rocky slopes/outcrops, and open woodlands, preferring well-drained sandy or loamy soils. This species is valuable for soil stabilization, erosion control, and prairie restoration projects, providing food and cover for birds and small mammals. Its adaptability makes it a useful addition to native plantings, wildlife habitats, and drought-resistant landscapes.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful 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.
