Of Note

It is a member of one of the planet’s oldest clan of trees (Platanaceae) and paleobotanists have dated the family to be over 100 million years old.

Sycamores grow quickly and can live for hundreds of years.

Very often it divides into two or more trunks near the ground and its massive branches form a wide, irregular crown.

Coloring of mottling, leaf teeth/sinuses all different. Seed pods single vs pair in planetree.
