"London planes are phenomenally sturdy street trees – they’re called “London planes” because they are and were so common throughout London, and while yes this is due to their attractiveness, it’s also because they were able to grow in the soot filled air of 19th century cities, and so became exceedingly popular, especially in London with its thick industrial era atmosphere.

The London Plane is of hybrid origin – it is the offspring of two different species, the American sycamore (Platanus occidentalis) and the Oriental plane (Platanus orientalis), and it is a tree that did not exist prior to European colonization of the new world.

Before then, American sycamores and Oriental planes were kept separate by an ocean (the Atlantic if you’re going east from the US, or the Pacific if you want to go all the way around the other way), and they didn’t come together until the 17th century, when ... a botanist and gardener ... came to the colonies in the early part of that century and in 1636 took the American sycamore to England."
