Slender Wheatgrass (Elymus trachycaulus)

Slender Wheatgrass

Elymus trachycaulus

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

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.
