Le genêt à balai (Cytisus scoparius [L.] Link.) est une légumineuse arbustive vivace exotique à feuilles caduques qui, dans le cours du siècle qui s'achève, a fortement agrandi son aire de répartition le long des zones côtières du Pacifique et de l'Atlantique ainsi qu'en Australie, en Nouvelle-Zélande, en Afrique du Sud, au Chili, en Iran et en Inde.

Scotch broom (Cytisus scoparius (L.) Link.) is an exotic perennial, leguminous, deciduous shrub, which during the past century has greatly expanded its range along the Pacific and Atlantic coasts of North America, and in Australia, New Zealand, South Africa, Chile, Iran, and India. This shrub rapidly invades disturbed areas, forming dense thickets which can suppress and inhibit native vegetation, including economically important conifer seedlings. The developmental characteristics whereby Scotch broom invades new sites include specialized stem photosynthesis, prolific seed production, longevity of seeds in the soil, and nitrogen fixation. Human activities such as planting along highways for beautification and prevention of soil erosion have accelerated the problem of rapid geographical dispersal. Various methods of control (chemical, manual, and biological) together with habitat, morphology, reproductive biology, growth and development are discussed.
