Chinkapin Oak
Quercus muehlenbergii
An underused white oak with chestnut-like toothed leaves, prized for tolerating dry, alkaline, limestone soils where most oaks struggle. Sweet acorns feed wildlife; it transplants poorly from the wild because of a deep taproot, so plant young nursery stock.

Common questions
Will chinkapin oak grow in alkaline soil?
Yes — it is one of the best large shade oaks for high-pH, limestone, and dry soils, where pin and red oaks often turn chlorotic. That alkaline tolerance is its standout landscape trait.
Is chinkapin oak the same as chinquapin?
The name is shared but the plants differ: chinkapin oak is a true oak (Quercus muehlenbergii), while the Allegheny chinquapin is a small chestnut relative (Castanea). The oak's leaves merely resemble chestnut/chinquapin foliage.
