Elymus hystrix is a native perennial grass that forms upright clumps with distinctive bottle-brush seed heads. It tolerates partial shade better than most grasses and provides good texture in naturalized areas. The grass goes dormant in winter, leaving attractive tan stems that can be cut back in spring.
In an HOA neighborhood
Bottlebrush Grass takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Seed heads can appear wild and unkempt
- Dormant winter appearance looks messy
- May self-seed creating informal patches
