Ficus burtt-davyi is a very useful plant for bonsai. It can form nice bonsai in even small size due to its leaves that can become quite small under proper cultivation. There are also several clones that vary from normal to very small leaves.

The photos below show a larger BD fig that was cut into pieces and the one circled in red is a very small piece that was potted up.

The last shot shows the small tree after about 5 years of growth.
