In the mountains of central Europe, the sycamore lives an irreproachable life. But bring it into British towns, as we have done en masse, and it becomes a hooligan. It is one of nature鈥檚 several urban bad pennies. Its leaves attract aphids which spit out the sticky honeydew that coats our cars so tiresomely each summer. The leaves, slimy when fallen, were once cited by British Rail as 'the wrong sort' and the cause of winter chaos. Prodigious in its seed production, it seems unstoppable in its spread. Its seedlings pop up everywhere. But for all that, it is a city tree and city trees absorb our pollution.
