Cytisus is a genus of flowering plants in the family Fabaceae, native to open sites (typically scrub and heathland) in Europe, western Asia and North Africa. It belongs to the subfamily Faboideae, and is one of several genera in the tribe Genisteae which are commonly called brooms. They are shrubs producing masses of brightly coloured, pea-like flowers, often highly fragrant.{{cite book|title=RHS A–Z encyclopedia of garden plants|year=2008|publisher=Dorling Kindersley|location=United Kingdom|isbn=978-1405332965|pages=1136}} Members of the segregate genera Calicotome, Chamaecytisus, and Lembotropis are sometimes included in Cytisus.{{cite web |url=http://www.ildis.org/LegumeWeb?version~10.01&genus~Cytisus&species~ |title=ILDIS LegumeWeb entry for Cytisus |author= |website=International Legume Database & Information Service |publisher=Cardiff School of Computer Science & Informatics |access-date=17 April 2014 }}
