The leaves are light green, large, and thick. They grow 6-12 inches wide and contain 3-5 lobes.
These native plants produce fruit in the form of a small seed ball that hangs in clusters of 2-7, each containing one seed. The outside of the seed ball is covered in dense, tiny flowers.
Is sycamore the same as planetree?
Yes, they are the same. It gets confusing because there are several varieties of sycamores, and many have the common name of planetree.
However, it is most often the London planetree that gets confused with the California sycamore. The London planetree is actually a hybrid plant type since it’s a cross between the American sycamore and oriental sycamore.

Platanus racemosa, the California sycamore, has a canopy spread of 75-100 feet wide. The London planetree’s spread is 65-80 feet wide.
The individual leaves of Platanus racemosa have less noticeable lobes. The London planetree is more distinctive like a maple tree leaf.
The mottling on the bark of Platanus racemosa starts higher up the trunk. In contrast, the London planetree has mottling all the way to the base of the trunk.
In Platanus racemosa the fruits containing the seeds hang individually, and the London planetree fruits hang in pairs.
