Flowering also changes the palatability of tagasaste. Tagasaste is considered to be a promiscuous legume, compatible with cowpea and Tagasaste 1502 Rhizobium. A breakthrough came with the discovery that cattle can be set stocked on tagasaste. There are now about 100,000 ha of tagasaste in Western Australia. These phenolic compounds make the tagasaste less palatable and reduce the animals' feed intake. In Australia a prostrate form of tagasaste has been developed by selection, called Weeping Tagasaste. Sheep can not be set stocked on tagasaste as this can lead to plant deaths. Sheep can remove every leaf from tagasaste but this does not cause plant deaths. Tagasaste ("Chamaecytisus proliferus"), a Canary Islands native, is widely grown as sheep fodder. Kew Gardens tested tagasaste and then sent seed to all its colonies around the world. Tagasaste is an evergreen shrub that has rough yellow-grey bark and velvety hairy young growth.
