Castanea sativa is a large, deciduous tree species from the Fagaceae family. It is commonly known by the names Sweet Chestnut, Spanish Chestnut, Common Chestnut and European Chestnut, amongst others. This plant produces edible nuts, enclosed in spiny burrs, termed Chestnuts. The female flowers develop into tasty chestnuts, protected by the spiny outer casing, dropping to the ground as they ripen. The leaves turn a glorious yellow before falling in autumn. So not only is the Chestnut a large fast-growing tree with delicious edible nuts that are widely used in the culinary and medicinal applications, but also a handsome specimen to grow in a garden or a park.
