planetree

Planetree, also called the plane tree, is a common name for trees in the genus Platanus (family Platanaceae). The genus includes several species native to the temperate regions of the Northern Hemisphere and many of which are widely planted beyond their native ranges. The London plane (Platanus × hispanica) is the best-known urban form, a hybrid between P. occidentalis and P. orientalis.

Plane trees are large deciduous trees characterized by broad, palmately lobed leaves resembling maples and a distinctive patchy, peeling bark that reveals a light-colored inner surface. They produce long, hanging catkins as inflorescences; trees are monoecious, with male and female flowers on the same plant. The fruit forms a dense spherical head of many small achenes that persist into winter and are dispersed by wind.

Native to North America, Europe, and parts of Asia, plane trees tolerate urban conditions, pollution, and a wide range of soils, though they prefer moist, well-drained sites. They are commonly planted as street trees, in parks, and as ornamental specimens due to rapid growth and broad canopies that provide substantial shade.

Uses and ecology: Wood from plane trees is a hardwood used for veneer and furniture. In urban environments they supply shade and aesthetic value but shed substantial litter in leaves and fruit. They can be susceptible to certain diseases and pests, and their large root systems may interfere with sidewalks or foundations if planted too close to infrastructure.
