Pyramidal through early maturity, its form turns more oval in older age. Fast-growing, tolerates wet soils, likes full sun. Glossy dark green leaves turn russet, bronze or red. Grows to 60' to 70', 25'-45' spread. (zones 4-8)
The pin oak can be expected to grow in Hardiness Zones 4–8. View Map
The pin oak grows to a height of 60–70' and a spread of 25–40' at maturity.
This tree grows at a fast rate, with height increases of more than 24" per year.
Full sun is the ideal condition for this tree, meaning it should get at least six hours of direct, unfiltered sunlight each day.
The pin oak grows in acidic, loamy, moist, rich, sandy, well-drained, wet and clay soils. It can tolerate wet conditions, including moderate flooding.
Has a distinctive branching pattern that sets it apart, especially in winter.
Provides great fall color, with leaves turning shades of scarlet and bronze.
Is easier than most to transplant.
Features glossy, dark green leaves that are 3–6" long with 5 lobes (although sometimes 7–9) separated by very deep sinuses.
Produces yellow-green catkins that are 5¬–7" long and typically appear in April and May.
Yields acorns that are nearly round and ½" long with a thin, saucer-like cap made of small, tight scales.
Offers dense shade.
Tolerates heat, air pollution and compacted soil.
Develops a single, central trunk from ground to tip.
Grows in a pyramidal shape.
Cannot tolerate alkaline soils.
Pin oak acorns are eaten by many songbirds, wild turkeys, white-tailed deer, squirrels and smaller rodents but are a particularly important food for many ducks.
The name pin oak comes from its short, tough branchlets located along the branches and limbs. Because of its tolerance for wet conditions, the tree is also known regionally as swamp oak, water oak and swamp Spanish oak. The tree was first observed scientifically prior to 1770.
