Cytisus scoparius (Wikipedia) Cytisus scoparius (syn. Sarothamnus scoparius), the common broom or Scotch broom, is a deciduous leguminous shrub native to western and central Europe. In Britain and Ireland, the standard name is broom; this name is also used for other members of the Genisteae tribe, such as French broom or Spanish broom; and the term common broom is sometimes used for clarification. In other English-speaking countries, the most common name is “Scotch broom” (or Scots broom); however, it is known as English broom in Australia.
