The Brachychiton and Allied Genera Study Group is one of over 20 such Groups whose aims are to further knowledge about the cultivation, propagation and conservation of specific Australian plants. The Study Group publishes regular newsletters documenting reports from members into cultivation issues, propagation methods and natural occurrences of different species.
A number of species of Brachychiton are well known in cultivation. The best known is the spectacular Illawarra Flame Tree (B.acerifolius) and others widely grown are the Kurrajong (B.populneus) and the bottle tree (B.rupestris). Although mainly concerned with Brachychiton, related genera within the Sterculiaceae family are also considered. These include Guichenotia, Lasiopetalum, Lysiosepalum, Rulingia and Thomasia. Reports from Study Group members have assisted in assessing the suitability of various species for cultivation in a range of climatic zones.

Members of the Study Group are mainly keen amateurs with no formal horticultural or botanical knowledge, although a number of professionals in those fields also participate. As in all study groups, the members' work is mainly carried out in their own homes and gardens and in their own spare time.
