Facts About

Smooth hawk's-beard is native to Europe and has been introduced across much of North America, although it is sparse in most areas. It colonizes fields, roadsides and areas with disturbed soils. Like the other hawk's-beards (Crepis) the young leaves and shoots are edible.

Habitat

Anthropogenic (man-made or disturbed habitats), meadows and fields
