Pin oak (Quercus palustris)
Tree in photo is south of the Recreation Center near the bus stop
Dozens of these medium size oak trees line Bill McDonald Parkway from the Sehome Village to the Recreation Center. It is a shapely, fast-growing, easily maintained tree with superior fall colors. The name "pin oak" is possibly due to the many small, slender twigs, but may also be from the historical use of the hard wood for pins in wooden building construction.
Pin oaks are native to central and eastern North America. They have a life span of up to 175 years, and can reach heights approaching 150 ft., assuming errant drivers do not hit them first. It is a popular tree for lining boulevards due to its disease resistance and low maintenance requirements.
