Brooms are a group of evergreen, semi-evergreen, and deciduous shrubs in the subfamily Faboideae of the legume family Fabaceae. All genera in this group are from the tribe Genisteae. These genera are all closely related and share similar characteristics of dense, slender green stems and very small leaves, which are adaptations to dry growing conditions.
Most of the species have yellow flowers, but a few have white, orange, red, pink or purple flowers. Brooms tolerate (and often thrive best in) poor soils and growing conditions.
In cultivation they need little care, though they need good drainage and perform poorly on wet soils. They are widely used as ornamental landscape plants and also for wasteland reclamation (e.g. mine tailings) and sand dune stabilising.
