Blackjack Oak

Also known as Barren Oak, Black Oak, Jack Oak

Blackjack oaks thrive on poor, dry, acidic soils where other hardwoods struggle, forming stunted, gnarled silhouettes across barrens and open savannas. Thick, blocky, near-black bark helps them withstand periodic ground fires, while broad, leathery, three-lobed leaves minimize moisture loss in baking heat. Their bitter acorns take two seasons to mature, providing a critical winter food reserve for wild turkeys, deer, and small rodents.
