Species:

Family:Fagaceae

Bartram Oak is a sizable deciduous tree belonging to the Fabaceae family, commonly known as the beech family. This tree thrives in the central and eastern regions of the United States, emerging as a natural hybrid of Quercus phellos and Quercus rubra, both of which grow in the same areas. Due to its hybrid nature, the leaves can vary significantly, even on a single tree. The acorns produced are typically small and almost stemless. Like all oak species, Bartram Oak attracts a diverse array of wildlife, including birds, butterflies, moths, and various mammals.

For optimal growth, it should be planted in full sunlight and in moist, acidic soils, although it does not require excessively fertile ground. The tree features a rounded crown with an open branching structure, making it an excellent choice for providing shade in large yards, parks, or other public spaces.
