Hairy Woodrush

Luzula acuminata

Hairy Woodrush is a small, clumping perennial grass-like plant that grows up to 1.5 feet tall. It is found in forest clearings, streambanks and woodlands, often thriving in moist, rich soils with moderate drainage. Its foliage is semi-evergreen and covered in fine hairs, with delicate brown flowers appearing in late spring. This species is useful for woodland ground covers, shaded rock gardens, and erosion control in moist, shaded areas.

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.
