Pin Oak

Pin Oak

Closeup of Bark and Leaves Pin Oak Tree

The Pin Oaks are some of the most majestic tree specimens on campus. Often considered overused in the landscape, this tree is still a good selection for wet planting areas prone to occasional flooding. Roots can grow shallow especially in wet areas causing grass to thin out. Alkaline soils can cause chlorosis, a need for iron that turns the leaves a sickly yellow. These problems are best avoided by selecting an area with moist acidic, iron-rich soil to plant the tree.

Bark: The bark is grayish brown and with age becomes lightly furrowed.

Foliage: alternate, simple, elliptical leaves are lobed 5-7 times and are 3 - 6 inch wide and long. In the fall, the tree is a brilliant red to bronze color. Some brown leaves do not drop off during winter months.

Flowers: The flower is brown and not considered showy.

Fruit: The 1/2 inch tall and 2/3 - 3/4 inch wide acorns are attractive to squirrels, and mature the second year. Acorns are considered a walking-hazard along public walkways.
