Sycamore (Platanus occidentalis) is a large shade tree, abundant Throughout the UK. It grows fast and lives long in moist lowlands. Its roots are vigorous enough to take out a pavement, but do not descend very far into the ground.
Some varieties of sycamores grow to 30 m (100 feet) tall with a 21 m (70 foot) spread. Its bark is distinctive -- white and exfoliating -- while its broad crown offers dense shade. Like other quick-growing trees, the sycamore produces vigorous surface roots.
Sycamore is a common tree in the UK, found in woodlands and gardens. It serves better in the country than the city, as its shallow, aggressive root system mandates planting at least 3.6 m (12 feet) from a pavement.
The sycamore is a "windfirm" tree. Its widespread, strongly branched root system keeps it firmly anchored in the soil. The majority of its roots are found no deeper than about 60 cm (a few feet) from the surface of the soil.
