American Beech. Fagus grandifolia. This native north american tree growing up to 70 feet or more tall and 40 foot wide. Cold hardy into zone 3. Edible portions include the nuts (especially roasted), inner bark, and young leaves. Like most seedling native trees, it takes a while to bear, often decades. The tree will live and produce food and materials for 300 years. A good candidate for coppicing and pollarding, with recuts possible at 4 year intervals. Search Coppicing on the website. Will grow in sun, but is very tolerant of shady conditions, stemming from its evolution as a climax species in eastern temperate forests.
