Plane tree
Platanus (genus)
Also known as: Platanus, London plane, sycamore (American usage)
A genus of around 11 species of large deciduous trees in the family Platanaceae — distributed across the temperate Northern Hemisphere. The London plane (*Platanus × acerifolia*, a hybrid of American and Oriental planes) is one of the most-planted urban shade trees in temperate cities globally — its extraordinary pollution and compaction tolerance has made it the default major-city street tree from London to New York to Paris. The Oriental plane (*Platanus orientalis*) is one of the most heavily symbolic trees in ancient Greek tradition — Hippocrates taught medicine under a plane tree on Kos, and the species is sometimes called *the tree of Hippocrates*.
Scientific
Platanus (family Platanaceae) contains ~11 species across the Northern Hemisphere. The English-language naming is confusing across regions:
- Platanus in general — “plane tree” (British, European)
- Platanus occidentalis — “[[american-sycamore|American sycamore]]” (American usage); covered at [[american-sycamore]]; same genus as the European plane trees but Americans call it sycamore
- “[[american-sycamore|Sycamore]]” in British English — refers to the unrelated Acer pseudoplatanus (a maple)
- The London plane — Platanus × acerifolia — is a hybrid of the American and Oriental species
Principal species:
- Platanus × acerifolia — London plane; the urban-tree workhorse
- Platanus orientalis — Oriental plane; ancient Mediterranean species
- Platanus occidentalis — [[american-sycamore|American sycamore]]; eastern North America
- Platanus racemosa — [[berkeley|California]] [[american-sycamore|sycamore]]
The distinctive Platanus feature is the bark — pale and mottled with peeling patches in cream, tan, and grey-green, giving mature trunks a camouflage-like patchwork appearance.
Cultural and historical
The Oriental plane appears repeatedly in classical Greek tradition. Hippocrates is said to have taught medicine under a plane tree on the island of Kos; the species was sacred to Apollo and Helen of Troy. The Plataniste — a sacred plane grove — was a feature of multiple Greek city-states.
Modern London plane is the urban tree par excellence. The species was first hybridized in 17th-century Spain (Tradescant the Younger imported both parent species to London, where the natural cross likely first occurred) and within a century had spread to street plantings across European capitals.
The species’ urban dominance reflects specific tolerances:
- Air pollution (the bark shedding may help slough off accumulated soot)
- Soil compaction
- Drought once established
- Hard pruning (the pollarding tradition keeps Parisian planes at controlled heights for centuries)
