Sweet Chestnut (Castanea sativa): European Nut Tree

Sweet chestnut, or Spanish chestnut, is a large deciduous tree native to southern Europe and Asia Minor, cultivated for millennia for its edible nuts and durable timber.

Botanical Profile

Description and Features

This long-lived tree reaches 80–100 feet with a massive trunk and broad crown. Leaves are long, lanceolate, sharply toothed. Flowers are long, yellow catkins. Fruit is a spiny bur containing 2–3 shiny brown nuts. Bark is deeply fissured, spiraling.

Cultivation and Uses

Sweet chestnut prefers full sun, well-drained, acidic soil. It is grown for nuts (roasted, flour), timber (fence posts, furniture, barrels), and tannin. Many cultivars exist for nut size and flavor. It is susceptible to chestnut blight, though less than American chestnut.
