Pin Oak, scientifically known as Quercus palustris, is a large deciduous tree native to eastern North America. Here are some key points about this tree:

1. Appearance: Pin Oak is known for its distinctive pyramid-shaped crown with horizontal branches that often droop towards the ground. The foliage consists of deeply lobed leaves with bristle-tipped lobes, resembling the shape of a pin, hence the name "Pin Oak." In the fall, the leaves turn a reddish-brown or russet color before dropping.

2. Size: Mature Pin Oaks typically reach heights of 50 to 70 feet with a spread of 40 to 60 feet. However, under optimal conditions, they can grow even larger.

3. Growth Rate: Pin Oaks have a moderate to fast growth rate, especially when young. They can add 1 to 2 feet (30 to 60 cm) of growth per year.

4. Sun and Soil Requirements: Pin Oaks prefer full sun to partial shade and thrive in moist, acidic soils. They are commonly found in low-lying or wet areas such as swamps, bottomlands, and along streams. They are tolerant of occasional flooding and wet conditions but can also adapt to drier soils once established.

5. Hardiness: Pin Oaks are hardy in USDA zones 4 to 8.

6. Landscape Use: Due to their size, attractive foliage, and tolerance of wet soils, Pin Oaks are commonly used as shade trees in parks, large landscapes, and along streets. They also provide valuable habitat and food for wildlife, including birds and small mammals.

Overall, Pin Oak is a beautiful and adaptable tree that adds beauty and shade to a variety of landscapes. Its distinctive foliage and attractive form make it a popular choice for homeowners and landscapers alike.
