Cytisus proliferus, tagasaste or tree lucerne, is a small spreading evergreen tree that grows 3-4m high. It is a well known fertilizer tree. It is a member of the Fabaceae (pea) family and is indigenous to the dry volcanic slopes of the Canary Islands, but it is now grown in Australia, New Zealand and many other parts of the world as fodder crop.
