In our recent wanderings around St George's Park (running the gauntlet of would be muggers, with pepper spray firmly in one hand and cameras in the other!!!) next to the Conservatory we walked under an amazing tree. It is a Ficus, but whether it is an actual rubber tree or just a close relative, I am not sure.
What I do know is that it was HUGE! Even with several photos stitched together it is impossible to convey the span of the branches, or the height of this tree. The trunk is surprisingly narrow to support such huge branches, but it has enormous buttress roots. (You can see one on the right of the top picture.) In fact the parks department even built a bridge so that the footpath could go over them. If you look very closely at the middle two, you can see Max, in a blue shirt, on the bridge, and that might help give you an idea of the scale of the thing.
