Sycamore trees loose their bark in thin plates. One freeskooler described the appearance of this rather awkward and conspicuous shedding as “camouflage-style” bark. Beneath the dark reddish scales a smooth, light grey bark is revealed. Another clue that you have found a sycamore is to spot the seeds which hang on through winter. These are found clustered in large, spiked spheres. Look up and enjoy the decorated canopy against the bright winter sky! The London planetree has similar bark, and is often found on city streets.
