Common names: common velvet grass; Yorkshire fog
Holcus lanatus (common velvetgrass) is a tufted perennial grass (family Poaceae) that tolerates high levels of heavy metals in the soil and sulfur dioxide in the air. It establishes best in moist conditions and is a facultative wetland indicator.Cal-IPC Rating: Moderate
