The London plane tree accounts for over half of our city's tree population. With such arboreal omnipresence it's easy to overlook just what a distinctive tree this is. The sight that catches at eye level and will be familiar to most people is its khaki camouflage-patterned bark. This mottled mix of grey, olive and cream is pleasing on the eye and if you could imagine such a thing as a benign militia lining our city streets, it would surely look something like a procession of London planes.

Yet despite the tree's ubiquity it was only 'discovered' in the mid-17th century by John Tradescant the younger in his famous nursery garden and ark in Vauxhall. And 'discovered' in the sense that there's a possibility the tree did not exist before this time.

So why was London's most popular tree so late on the scene?

Here we have to go into the tree's family history. The London Plane is most likely a hybrid between the American sycamore and the majestic Oriental plane. It took a long time for these 'lovers' to meet — the two trees thwarted by growing on opposite sides of the globe. But it seems the voyages of the early modern period with routine collections of specimens being brought home led to the American sycamore's journey from its native eastern America, and the Oriental plane from southeast Europe. The first account of the Oriental plane in Britain is found in William Turner's 1548 book: Names Of Herbs. While the American sycamore perhaps arrived some 150 years or so later at the beginning of the 17th century.

The London plane would then have hybridised when its 'parents' found themselves sharing the same space. There is some probability that this was in the very Vauxhall garden where Tradescant first found the tree since both requisite family members were indeed there.

But how did it go from interesting curiosity to the urban tree of choice lining so many of London's streets? It was planted en masse at a time when London was black with soot and smoke from the Industrial Revolution and when population expansion forced greater urban planning. Taking a cue from the plane-lined boulevards built in Paris from around 1850, the tree flourished in London due to its hardy characteristics.

Take that camouflage bark, for instance, it's more than just an accidentally attractive quality. It has that pattern because the bark breaks away in large flakes in order that the tree can cleanse itself of pollutants. It also requires little root space and can survive in most soils. True, it grows to some 30 metres tall so when trees line a street they can cause problems for London buses and overhanging wires. But then it's also an unusual tree in that it can flourish despite pollarding (the pruning of branches that often gives the tree a club-limbed appearance). The rather beautiful maple-like leaves, shaped like a five pointed star, also have an otter-like sleekness. The daily London grime simply rinses away, leaving the leaves a lush green.

However, the plane does maintain many of its ornamental qualities too. The best place to view the tree is perhaps Berkeley Square. Here the 30 or so examples were planted in 1789 and are among the oldest in London. What's more, due to the height by which the branches expand into a canopy like structure, Berkeley Square is one of only a few where it's possible to peer into the square from a distance (usually while attempting to cross the Mayfair streets).

The one real negative quality is for allergy sufferers, who must be wary of the spores released from the tree's fruit. But those that don't have this to consider will find these comical little baubles another pleasing quality.

All in all it is a tree that can be said to be a true Londoner born and bred, to the extent that it even took the city's name.

I think it interesting that we don't know how old they reach as none have yet to die from natural causes.

So does that mean the the Parisian planes are a different species which arose from hybridisation in France, or that one of our countries pinched saplings from the other?

Love that last image, a gem.

I still can not see any reason for the London Plane tree, it is possible to get the same effect of cover with most traditional English trees, such as the Oak Tree. One has only got to visit other Forestry areas in the UK to see this. Another reason for other English trees would be that London children would learn how a tree originates.

Just in case people are not aware the American Sycamore is not a maple like our own common sycamore tree, but a plane tree Platanus Occidentalis. We have the other parent plane (Oriental Plane) in our Alexandra Park. https://www.flickr.com/photos/... https://www.flickr.com/photos/...

I've always loved the London Plane. I used to be fascinated with the trees on Loftus Road which are as high as tge 6 story town houses and block out tge light in the height of summer, but they look thier best along the banks of the Thames. Thank uou for explaining their history.

I'd never had hayfever or other allergies in my life but this flaming tree now makes it impossible for me to enjoy a lunchtime walk anywhere in London during spring months. That evil fluffy brown Plane Tree pollen makes me an all-day prisoner in my workplace. Time for a cull!

Another wonderful place to see London Plane trees is in Kensington Gardens. The gardens have some of the oldest Plane trees in London - Lancaster Walk runs throught the centre of the gardens and is lined with London Planes... see more here ...

"It was first recorded in Spain in the 17th century, where P. orientalis and P. occidentalis had been planted in proximity to one another." This according to Wikipedia, but I didn't find any other source which gives London as first place of its recording. In fact another of its name is Platanus x hispanica.

Cornwall Gardens SW7 has a nice selection that were planted 1840-60, have never been pollarded and are now about the size of the tall victorian town houses.
