Handsome tree, similar to White oak but with different leaves. A number grow in the dry, shallow soil of the serpentine barrens in Nottingham Park in southeastern Pennsylvania. I just don't see this tree growing everywhere. I see one in a parkway of a bank a few miles down the road. It is slow growing, about 6 to 9"/yr and develops a taproot so that regular nurseries don't grow it. It lives over 400 years.

Surprise! Yet another broad leafed, deciduous oak with big acorns that can be found growing in parts of Florida. This popular east coast shade tree is naturally occurring usually in wetlands around Ocala, Gainesville and of course the pan handle redion. It can be growth farther south with success.

Rounded mature growth shape to 30-70 feet. Slow growth. Brownish fall color.

Not only are the acorns used by wildlife, the leaves are used for birds' nests and tree cavities are homes to wildlife.

The post oak requires full sun.

One of the great hardwood oaks that grace this area. They get quite large...sometimes over 70 feet. The acorns are attractive to many types of wildlife that depend on the nuts for winter food.

Called 'Post' oak for the tradition of using the wood for fenceposts.

One of the easiest ways to identify the Post Oak is to look at the leaves. The leaves are lobed in such a way to resemble a Christian cross.
