The London planetree is a widely planted street tree, and for good reason. Its attributes were discovered in London where the new hybrid first appeared around 1645. The tree was found to thrive in the sooty air and provide wonderful shade. Its ability to withstand air pollution, drought and other adversities assures its popularity as an urban tree. Strong limbs also help make the London planetree a good choice where site conditions allow for its large size.

Beyond its reputation as a survivor, this tree is simply worth admiring. The unique bark and interesting branching give it amazing visual appeal—whether summer or winter.

History/Lore

The London planetree is believed to have resulted from a cross between the Oriental planetree and the American sycamore. While the exact details of the tree’s origin have been lost over time, it was discovered that this hybrid could tolerate the smoke and grime of London. As a result, it has been widely distributed to cities throughout the moderate climate regions of the world for nearly 400 years.
