Scotch Broom - Cytisus scoparius
THIS PAGE IS UNDER CONSTRUCTION.
Cytisus scoparius (Common Broom; syn. Sarothamnus scoparius) is a perennial, leguminous shrub native to western and central Europe from the Iberian Peninsula north to the British Isles and southern Scandinavia, and east to Poland and Romania, where it is found in sunny sites, usually on dry, sandy soils at low altitudes.
Scotch Broome has been introduced into several other continents outside its native range, where it is regarded as a noxious invasive species in many places such as California and the Pacific Northwest in North America, Australia and New Zealand. The prolific growth of this species after timber harvest inhibits reforestation by competing with seedling trees. Oregon estimates that it is responsible for $47 million in lost timber production each year in that state. Some attempts have been made to develop biological controls in affected areas, using three broom-feeding insects, the psyllid Arytainilla spartiophylla, the beetle Bruchidius villosus, and a moth Leucoptera spartifoliella.
