Known also as the Great Maple or False Plane, the Sycamore is in fact not a native tree, but appears to have been introduced from the continent in the fifteenth century. Capable of surviving in exposed and coastal contitions, the vigourous species survives between 150-250 years and has established itself across the United Kingdom. The leaves of Sycamore are heart-shaped and cut into five lobes 6-8 inches across. The flowers are similar to that of the Field Maple, but larger, and in a long hanging raceme. The black patches so frequently seen on Sycamore leaves are the work of a small fungus Rhytisma acerinum that can look unsightly but seldom cause health issues to the tree. A good choice for exposed sites where quick establishment is desired.
