A European species, sometimes grown as a low ground cover (usually 15–30 cm tall), but becoming a weed of roadsides, banks, clearings, fields, railroads, old homesites, and neglected lawns; often spreading from cemeteries. First collected in 1874 in Wayne Co.
The abundant, crowded, narrowly linear leaves with milky juice make this an easily recognized plant in the field, even when vegetative. The leaves are especially dense on lateral shoots, which eventually overtop the inflorescence (which is not overtopped in E. virgata).
