Facts

Common gorse is native to central and western Europe, where it is an important component of native heathland. It has been introduced in much of the temperate world, and is considered invasive in many countries. It was introduced as an ornamental in eastern North America in the early nineteenth century and has become established in the Northeast and the West Coast. In New England it is found in Massachusetts in open, sandy areas of the coastal plain.
