Brachypodium sylvaticum ssp. sylvaticum

Perennial tufting non-native grass that remains green well into the fall. Invasive. It can form dense patches in acidic or basic soils, in sun or in shade. It is probably overlooked and has a more extensive distribution than documented. See this NYS DEC video for general identification: https://www.youtube.com/watch?v=0zzGMvXngaU
