Common Name: Slender false brome
Scientific Name: Brachypoidium sylvaticum
Origin: North Africa and Eurasia


Slender false brome is a perennial grass that grows in dense clumps. This species has long, drooping, bright green leaves 5-12 mm wide, which can be covered in long, sparse hairs or may be hairless. Its flowering stalks grow up to 2 ft. high with drooping inflorescences. The flowers bloom and form seed between June and September.


Slender false brome can grow in forest understories, open meadows, riparian sites and forest edges. It is often along hiking trails and deer trails.


Slender false brome produces plentiful seeds which can easily spread on hiking equipment, footwear and on deer. It quickly forms dense, single-species colonies which crowd out understory plants. This plant is also not very palatable to wildlife or livestock.


Spread prevention and containment efforts, which include cleaning off footwear, hiking gear and vehicles after entering infested areas, are important. Mowing and herbicide treatments are common control methods for this plant. Mowing year after year can exhaust the seed bank, but may need to be combined with other management methods to achieve full control. Hand pulling is recommended only for small patches, and should be done during the spring (prior to flowering).
