To the inexperienced gardener, a sycamore and a London planetree may look like they are the same tree, but this is not the case. The London planetree is a hybrid plant, and one of its parent species happens to be the sycamore. Due to that lineage, these trees have similar leaves, bark, and fruits, leading them to look nearly identical in some cases. However, there are subtle differences in the appearances of these trees, one of which is that London planetree trunks usually show more of the exfoliating camouflage bark pattern.
