Native to Europe, the Mediterranean area. A garden or hedge plant that has become established throughout higher rainfall parts of the State, and readily invades disturbed areas such as roadsides, fence-lines and grazing land. Declared a noxious weed in Victoria.

Plants may not always be readily distinugished from Genista stenopetala and G. ×spachiana. There are taxonomic difficulties in this group and interspecific hybridization appears to be rather common. These 2 species vary only in their many-flowered terminal racemes and slightly larger leaflets but these features, on some specimens, grade into G. monspessulana. The majority of collections in Victoria are included in G. monspessulana.
