Castanea sativa (Sweet chestnut) - Plant
Castanea sativa, or sweet chestnut, is a species native to Europe and Asia Minor, and widely cultivated throughout the temperate world. A substantial, long-lived deciduous tree, it produces an edible seed, the chestnut, which has been used in cooking since ancient times. C. sativa attains a height of 20?35 m (66?115 ft) with a trunk often 2 m (7 ft) in diameter. The bark often has a net-shaped (retiform) pattern with deep furrows or fissures running spirally in both directions up the trunk. The oblong-lanceolate, boldly toothed leaves are 16?28 cm (6?11 in) long and 5?9 cm (2?4 in) broad.
