The Burr Oak has several very unique traits among large shade trees and is a very important food source for wildlife. Growing in its native habitat at maturity can stand about 100' tall by 80' wide with fiddle-shaped foliage that is thick and large. The bark on lower trunks has thick, vertical flattened ridges with very deep furrows which produces large fringed acorns in the fall. It is also one of fastest-growing oaks and has been known to live 200-300 years. Displaying its bold texture of a massive trunk and huge spreading limbs attracts all forms of wildlife especially squirrels, deer and large birds. This oak is very drought tolerant due to its very deep taproot system and is cold hardy in zones 2-8. It is highly recommended that Burr Oak be planted in mid winter.
