Ponderosa Pine

Pinus ponderosa

Native to eastern Washington, this tree is an ambassador to the western United States.  It doesn’t attain the same size here in the Puget Sound, but it does retain all the beauty. On older trees, the bark develops cinnamon-yellow colored plates that are separated by deep fissures. The seeds are an important food source for wildlife.
