390 Japanese chestnut Castanea crenata Japanese Chestnut (Castanea crenata) is a species of chestnut originally native to Japan and South Korea. It is a small to medium-sized deciduous tree growing to 10-15 m tall. The leaves are similar to those of the Sweet Chestnut, though usually a little smaller, 8-19 cm long and 3-5 cm broad. The flowers of both sexes are borne in 7-20 cm long, upright catkins, the male flowers in the upper part and female flowers in the lower part. They appear in summer, and by autumn, the female flowers develop into spiny cupules containing 3-7 brownish nuts that are shed during October. 506540 Japanese Chestnut 390.jpg image/jpeg 143368 2012-04-20T09:44:15Z 417 Nuts Nuts Type 1 2011-02-09T00:37:39Z 2019-05-14T18:05:24Z false specific 103480 true FOOD00385
