Chestnut oak (also commonly called basket oak, rock oak and rock chestnut oak) is a medium to large sized deciduous oak of the white oak group that typically grows 50-70’ (less frequently to 100’) tall with a rounded crown.
It grows tallest in rich, well-drained soils. Insignificant monoecious yellowish-green flowers in separate male and female catkins appear in spring after the leaves emerge. Fruits are oval acorns with warty cups that extend to approximately 1/2 the acorn length.
