Spartium junceum, commonly known as Spanish broom or weaver's broom, is a species of flowering plant in the family Fabaceae, native to the Mediterranean in southern Europe, southwest Asia and northwest Africa, where it is found in sunny sites, usually on dry, sandy soils. It is the sole species in the genus Spartium, but is closely related to the other brooms in the genera Cytisus and Genista. There are many binomials in Spartium that are of dubious validity (see below).
