Cytisus scoparius

Cytisus scoparius (syn. Sarothamnus scoparius), the common broom or Scotch broom, is a deciduous leguminous shrub native to western and central Europe. In Great 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. Though this plant is native to Europe, it has spread to many other parts of the world. Scotch broom is now common in certain areas of North America and South America. This is because people started introducing Scotch broom to different areas of the world. After it was introduced in North America, Scotch broom was frequently planted in gardens. Later, it was used for erosion control along highway cuts and fills. There are other problems with Scotch broom as well. It is slightly toxic and unpalatable to livestock. It also has seeds that are viable for up to ten years, making them able to grow even after years of extermination.
