The scarlet oak is easily confused with the pin oak and the red oak; sharp eyes are needed to spot that the leaves are hairless on the underside, while the sinuses between the lobes are even more marked than on the pin oak. Bucculatrix domicola caterpillars decline to eat it.

The sycamore leaf is one of the less colorful: in autumn it simply turns yellow and brown, curls up and dies. Popular in parks, as it is a handsome, large tree that tolerates a wide range of soils, its downside is that the heavy weight of leaf fall creates plenty of autumnal work for gardeners.
