This is the Sweet Chestnut, 50-70 ft. high, native of Asia Minor, but now practically naturalized. It is a splendid ornamental tree, useful for fruit and timber, with large deep-green serrate leaves. There are several varieties, the best being aureo-marginata, in which the leaves are variegated with yellow. Young plants 1-7 ft. high sell well, and are raised from seed. Special varieties are grafted or budded.
Castanopsis chrysophylla, from North America, is closely related to the Sweet Chestnut, and is recognized by the yellowish under surface of deep-green ovate lance-shaped leaves.
