It is growing on an old wall and has been doing so for many years. It is about 10 feet high from the top of the high wall but I can't find a main trunk. I
expected to see a thick trunk but can only find lots of thick 'feeders' to the ground and across to a neighbours wall. It is my job to take this down and I am concerned that the plant will have eaten into the mortar between the bricks, leaving an unstable wall.
