About
The American chestnut (Castanea dentata) is a large, fast-growing deciduous tree of the beech family native to eastern North America. As is true of all species in the genus Castanea, the American chestnut produces burred fruit with edible nuts. The American chestnut was once common in the Appalachian Mountain range and was a dominant species in the oak-chestnut forest region of its central and southern range. During the early to mid-20th century, American chestnut trees were devastated by chestnut blight, a fungal disease that came from Japanese chestnut trees that were introduced into North America from Japan. Grow it in full sun and loam and sand soil. In UK gardens it is very hardy across most of the UK (RHS H6). It works well for architectural. It tolerates acid and neutral soils, well-drained conditions and south-facing aspects. Plant in well-drained soil in sun or partial shade.
