Elymus hystrix is a native ornamental grass known for its unique bottlebrush-shaped seedheads, which give it its common name. It provides shelter for small wildlife and insects and contributes to butterfly habitat, although it is not a direct nectar source. This grass tolerates a variety of conditions, including dry shade and clay soils. It is best propagated through seeds. 
Sow seeds directly in the garden in the fall or early spring, at a depth of approximately 1/4 inch. Make sure the soil remains consistently moist during germination and initial establishment. The seeds will germinate and establish themselves over time.
