Slender false brome (Brachypodium sylvaticum)

Slender false brome Synonyms: Festuca sylvatica

Common Names: False brome

Description: First recorded in the United States in 1939 from a collection near Eugene, Oregon.

Habit: Perennial grass that grows in clumps 12-18 inches high. In some locations, roots have a strong wintergreen aroma.

Leaves: Dense tufts of hairy, linear-lanceolate, 4-10 mm wide and up to 12 inches long, yellow-green, lax (floppy) leaves and long-lasting bright green color. Color remains late into the fall and early winter.

Stems: Covered in fine hairs and has sheaths that open to the base.

Flowers: Flowering stalks (culms) grow up to 3 ft tall and have densely hairy nodes and slightly elevated above the rest of plant. 4-12 spikelets (clusters of flowers) per culm and each have a tiny 0.5-2 mm long pedicel (spikelet stalk) which occurs singly at each node of inflorescence.

Fruit and seeds: Seeds are short-lived and no information is available on seed viability.

Habitat: Native to Europe, Asia and North Africa. Can be found growing on forest floors and open environments such as pastures and prairies at a variety of aspects and elevations. Known locations have been riparian forests to upland hardwood and conifer forests under patchy and closed canopies at elevations of 200-3500 ft.

Reproduction: By seeds that are short lived. Does not appear to be rhizomatous, but individual plants grow closely together and form dense, monotypic patches.

Monitoring and rapid response: Appears to be resistant to fire, re-sprouting within two weeks of a burn. Can be controlled using vegetative and pre-emergent herbicide or hot-foam (Waipuna). Also, hand-pulling in small locations can be effective. Combinations of control methods is most effective.
