Pin Oak
Quercus palustris

Height: 60 -70´
Habit: pyramidal becoming oval
Landscape Value:

The pin oak is the most common native oak used by homeowners today, and there are a number of reasons for its popularity. It transplants easily and is among the fastest-growing oaks, up to 2 1/2´ a year. The formal pyramidal habit also seems to hold great appeal and is a distinct feature in any landscape. Although it achieves great height, the pin oak requires a smaller area than most other oaks because its branches are not as wide-spreading. There are few pest or disease problems, but acid soil is absolutely a requirement; chlorosis (yellowing leaves) is certain to be a problem if this condition is not met. Its acorns are small but can be numerous, creating a maintenance concern in certain situations.

Seasonal Characteristics:
  • Summer: The medium green, glossy leaves provide a dappled shade that makes growing turf a possibility under these trees, especially when young.

  • Fall: Color varies between a rich deep red and a poor brown. Color is inconsistent and varies from tree to tree as well as from season to season.

  • Winter: The pin oak hangs onto its leaves for a good portion of the winter. Although brown, they are not unattractive and at the very least add a bit of movement to the landscape as they rustle in the wind.
Points of Interest:

The branching pattern of the pin oak is unique. The highest branches tend to point upwards, while the middle branches point straight out, and the lowest point downward. This distinct form is especially prevalent in younger trees; the canopy of older specimens tends to loosen and take on a more open and oval shape. The pin oak's strong wood warps during seasoning and is not valued as lumber.

 

Native Range:

Illinois, eastern U.S. south to Arkansas and west to Wisconsin. In the wild, it is found mostly in wet or swampy areas.
