Thanks! Ficus @ 12:24 is a Microcarpa, green something or other. I can never remember other than Microcarpa. Mounted to the rock about 20 years ago, well established but needs a bit of work to bring it current again.
The thorny bitches are Silk Floss trees. One flowers. One does not..... They arent really suitable for great bonsai, but they sure look cool.
