Also known as the common Fig and Chinese Banyan, this bonsai tree grows naturally in Southwest Asia. There are hundreds of species, most of them tropical and evergreen, although some are deciduous. Many varieties are natural dwarfs. Ficus is one of the most popular trees for indoor Bonsai. It is an excellent tree for beginners and pros alike. Virtually care free; they tolerate low light and humidity of a heated or air-conditioned house. The “banyan” style roots are commonly trained in a root-over-rock style.
