Overview: can grow to 35m and live for several hundred years. The bark is olive green to grey, with large scaly plates that peel off to reveal a creamy bark beneath. Young twigs are green-brown.
Leaves: sycamore-like leaves are leathery and thick, with five triangular lobes. They turn a rich orange-yellow before falling in autumn.
Flowers: London plane is monoecious, meaning the ball-shaped male and female flowers are found on the same tree, although on different stems.
