Finding the tallest tree in London.

It has been a question that has long fascinated me: what is the tallest tree in London?

You would think that you are no more than 1 google search away from getting the answer to this seemingly simple question but enter your question into google and it becomes quickly apparent that there is no general consensus on the topic, furthermore it seems nobody has even attempted to document it properly.

From my own experience I have 3 or 4 trees in mind which could hold the title, all of which are London Planes (Platanus Acerifolia - formerly Platanus x Hispanica) These are: 1. The Richmond Riverside Plane. Situated in the outdoor seating area of the steak restaurant, Gaucho's. This is my hunch for number 1 but I can find no official measurement of its height apart from 1 blog which had it at 38 meters. 2. The Carshalton Plane. A behemoth that stands by the river wandle in Carshalton and has no doubt feasted ravanously upon its gentle waters for the entirety of its life, explaining its monumental size. It may be larger by volume than the Richmond riverside plane as it splits into four stems at about 10m, each one being bigger than a big tree. 3. Richmond Riverside Planes. These two trees are known by some as "The twins" They are remarkable for their size and form and also for the fact that they are near identical clones of one another. The twin towers of the tree world. I oscillate in thinking which is the taller between these and the other Richmond plane, usually depending on which I happen to be squinting up at at the time.
