As you cross from the northern field into the middle field via the spiral bridge, you will immediately see another fine female Black Poplar (7) in front of you. She also snows in early June. Keep left and follow the path along the riverside. You will soon see a Dawn Redwood or Water Fir (8). These have the distinctive red bark but do not grow very tall like the Giant Redwoods. Again, it likes the moist soil of the river-side.
Next along this path is a fine row of London Plane Trees (10). The London Plane is not in fact a native, but thought to be a cross between the Oriental Plane and the American Plane. It was widely planted across London in the 19th century when urban pollution made it difficult for any tree to survive. Its waxy leaves and peeling bark, combined with its ability to grow in very poor soil made it the ideal tree for Victorian London.
