Geographical Distribution and Habitat
Castanea mollissima has from time immemorial been cultivated in parts of East Asia namely Korea, Taiwan and China. It can be found in areas close to the sea level and at attitudes which stretch up to 2,800 meters. In order to grow and flourish, the Chinese chestnut needs to be planted in an area with full and direct sun. The soil should be loamy and acidic.
When Castanea mollissima is planted near other chestnut species such as the Japanese chestnut, the American chestnut and the sweet chestnut, it cross pollinates to form hybrids. It has with time become resistant to the bark fungal disease known as chestnut blight.
Chinese chestnut produces edible nuts. In Eastern Asia, it is heavily cultivated in over 300 cultivars. Among the common cultivars include the Dandong chestnut, Meiling, Kuling and Nanking. Their nuts are usually sweet and ranked among the best in the whole range of chestnut species. The nuts are not only food to humans but also to wildlife. There are some species such as the American chestnut whose nuts are not as preferable for food.
