Burr Oak has several unique traits among large shade trees: fiddle-shaped foliage that is thick and large, bark on lower trunks that has thick, vertical flattened ridges with very deep furrows, large fringed acorns, and stout semi-corky twigs; in addition, the tree often stands alone in fields in the wild, displaying its bold texture of a massive trunk and huge spreading limbs from a distance, and being very drought tolerant due to its very deep taproot system
