Description

  • The Capitol grounds have five towering big-leaf maples with mossy trunks. Some of the group features licorice fern growing on their trunks. The species produces leaves larger than any other maple, often the size of a dinner plate, which turn golden and drop in October.
  • Deciduous, growing up to 160 feet tall with a trunk width of 70 feet.
  • Susceptible to maple tar leaf spot in the fall.
  • Landscape uses include specimen, shade tree, parks, large open spaces and nature-scaping.

History and significance:
These trees date from the 19th century and are native to the Capitol grounds. Washington's tallest big-leaf maple, in the Mount Baker National Forest, stands at 158 feet.
