Spain - Canary Islands; indigenous to the dry volcanic slopes of the Canary Islands
Chamaecytisus palmensis is listed on Tropicos, but GBIF gives the accepted name as Cytisus proliferus with Chamaecytisus palmensis as a synonym.
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. Some sources call it a shrub: Tagasaste is an evergreen shrub that has rough yellow-grey bark and velvety hairy young growth. Its leaves are composed of 3 greyish-green equal-sized leaflets, which are slightly paler on the underside. Its scented, creamy-white flowers form in small clusters in the leaf axils. Its flat pea-like pods are green, ripening to black. Listed as a shrub by Calflora.
Is now grown in Australia, New Zealand and many other parts of the world as fodder crop. The potential of tagasaste as a Spanish fodder was identified by Dr Perez, a medical practitioner, based on La Palma island in the Canary Islands in the 1870s, and Spanish cattle farmers. He wrote to the Spanish authorities promoting tagasaste as a fodder shrub but could not get them interested. He then sent seed to Kew Gardens in England. Kew Gardens tested tagasaste and then sent seed to all its colonies around the world. In Australia, tagasaste's potential was promoted by a number of individuals over the next century (e.g. Dr Schomburge in South Australia and Dr Laurie Snook in Western Australia) but was not adopted on a large scale until the 1980s in Western Australia.This species has been cultivated extensively as a fodder shrub and has sometimes also been used in land rehabilitation. It is also occasionally grown as a garden ornamental.
