Verbascum thapsus (common mullein, woolly mullein) is a biennial or annual forb (family Scrophulariaceae) that occurs throughout California, but is particularly abundant in dry valleys on the eastern side of the Sierra Nevada. High population densities have been observed in moist meadows and creek drainages near Mono Lake and Owens Valley. Common mullein is a host for insects that are themselves economic pests. Common mullein seeds can survive for 35 years or more in the soil.
