Erodium cicutarium (redstem filaree) is an aggressive annual/biannual (family Geraniaceae) that is very widespread throughout California and is commonly found along roadsides, grasslands, fields, and semi-desert areas. It often carpets large areas, out-competing native grasses and forbs.Cal-IPC Rating: Limited
