The turkey oak gets it's common name because of the shape of the leaf as it looks like a turkey foot.rayman wrote:Not to sound like a smart arse, a number of oak trees species are commonly referred to as blackjack oak including turkey oak, bluejack oak, post oak, southern red oak, true blackjack oak, and a hand full of others. We had a lot of turkey oaks in my yard growing up, which everybody called blackjack, and nearly every one of them that I ever cut down had heart rot. Made darn good firewood though.
Common names rarely refer to a specific tree species.
Blackjack oak.........................Quercus marilandica
Post oak.................................Quercus stellata
Turkey Oak............................Quercus cerris
All oaks make very good firewood and others like beech and hickory also make good firewood.
