Hardiest of the white oaks with a deeply grooved massive trunk and a wide-spreading crown of huge branches. Small branches are distinctively corky, winged and tend to twist and kink. The habit is upright and somewhat vase shaped.
Lustrous dark green foliage and large 1-2" acorns, each almost entirely enclosed in a fringed cup. These are edible and low in tannic acid; when roasted they supposedly make a decent coffee substitute. (For instructions on acorn processing, refer to Samuel Thayer’s Nature’s Garden.)
The strongly astringent inner bark, foliage and acorn caps are all medicinal. The most urban-tolerant oak.
Fairly fast growing. Needs full sun but adaptable to a wide range of soil types including clay. Monoecious, so you need only one to get fruit. Native to eastern U.S. and Canada. Z3. (2-4' bare-root trees)
