A very worthwhile fig to grow is Ficus rumphii. It is used extensively in southeast Asia for bonsai.
The pictures show two rumphii that I grew from seed and that are now 12 years old. The bark on this species is light in color as contrasted to religiosa which has a darker grey bark. Religiosa also has a longer drip tip on the leaves.
Upright style of rumphii, about 16″ tall
Slant style rumphii,15″ wide, the curving roots on the left will be removed.
