The blackjack oak is a very tough tree that can grow in undesirable locations - poor soil, rocky soil, or dry soil. Very drought tolerant. It is a small to medium sized oak, not growing nearly as large as other red oaks.
Southeastern US. West to Texas, north to extreme southern Iowa, east to New Jersey, south to the Florida Panhandle.
Dry, rocky, or poor soil
Blackjack oak is very unique in appearance, however the leathery leaves may resemble those of post oak from a distance. The bark and leaf shape will easily distinguish the two when observed up close.
