Full Answer

Under ideal conditions, the pin oak can grow to about 75 feet tall with a spread of up to 40 feet. It has a moderately fast growth rate. Though the bark of the pin oak is thin and fragile, the hard, strong wood is used in construction.

Pin oaks flower and leaf in late spring. Acorns are produced after two years and are about 1/2 inch long. The leaves have deep lobes and can grow to between 4 and 8 inches long. When they're turned over, small tufts of brown hairs can be seen along the axils. The pin oak has a symmetrical habit and produces deep scarlet leaves in the autumn. As the tree ages, the lower branches tend to droop. Generally, pin oaks don't live as long as other oak tree species.
