The London Plane is a large deciduous tree that grows 20-30 m (66-98 ft), more than 40 m (131 ft) in height, with a trunk up to 3 m (10 ft) or more, still around the perimeter. The skin is usually light gray-green, smooth and exfoliating, or yellow-brown and non-exfoliating. The leaves are thick and hard in structure, broad, palmately lobed, surface-like maple, petal 10-20 cm (4-8 inches) long and 12-25 cm (5-10 inches) wide, with petiole 3-10 cm (1 -4 inches) long. The young leaves are covered in the spring with small, fine, stiff hairs, which, however, disappear and at the end of the summer the leaves are hairless or almost gone. The flowers are lined with one to three (usually two) dense spherical inflorescences on a serpentine stem, with the male and female flowers on separate stems. The fruits ripen in about 6 months, up to 2-3 cm in diameter, forming a dense round cluster of tufts with many sharp hairs that help disperse the air; In winter, break the bunch slowly to release 2-3 mm of seed. The London plane is one of the most efficient small particle removal trees in the city. It has many visual similarities to the Platanus occidentalis from which it is derived; however, both species are relatively easily identifiable because the plaice is mostly planted in urban settlements, while P. Occidentalis often grows in low-lying and alluvial soils along streams.
