Description
Quercus macrocarpa develops into a broad, rounded shade tree for expansive lawns and park-like gardens. Its deeply furrowed gray bark, stout spreading branches, and large green lobed leaves give it a coarse outline. Yellow-brown fall foliage and large brown acorns with deeply fringed cups extend the seasonal display.
Grow it in full sun in neutral or alkaline, well-drained clay, loam, chalk, or sandy soil. It tolerates dry ground and drought but not prolonged flooding. The acorns support wildlife and are edible for people only after their tannins are leached or boiled out. Leaves and unprepared acorns can be harmful if eaten, with dogs and horses specifically identified as at risk.
