Castanea crenata

The Japanese chestnut or Korean chestnut is a small to medium-sized tree in the beech or Fagaceae family. It is native to Korea and Japan, growing to up to 12 m in height.

Japanese chestnut is noted for having resistance to chestnut blight which is the disease that has nearly wiped out the native American chestnut (Castanea dentata)

• Leaves are oblong-lanceolate, toothed, dark green, 7.5–17 cm long and 3.1–5 cm across, heart-shaped or rounded at the base, pointed; the teeth are small, with bristle-like points; lower surface covered with a close grey down; petiole is 1.2 cm long, downy; leaves turn varying shades of yellow and bronze in fall.
• The chestnut is monoecious; male flowers are small, pale green (nearly white) along a 15–20 cm long creamy yellow catkin; female flowers are creamy yellow-white along the base; both appear in early summer.
• Fruit is enclosed in a spiny husk up to 6 cm in diameter, with 1–3 edible brown nuts inside with white basal areas.
