Fagus crenata Fagus crenata Fagus crenata, known as the Japanese beech, Siebold's beech, or buna, is a deciduous tree of the beech genus, "Fagus", of the family Fagaceae. It is native to Japan, where it is widespread and often one of the dominant trees of Japan's deciduous forests. It is found from the Oshima Peninsula in Hokkaidō south to the Ōsumi Peninsula in Kyūshū. In north-east Honshū it grows in large stands from sea level up to but in the south-west of its range it is restricted to mountainous areas and occurs in small, isolated populations. It grows in well-drained, loamy or
Nyssa sylvatica long stalk and a rich source or nectar for bees. They are often dioecious so a male and female tree in proximity is required to set seed, however, many trees are also polygamo-dioecious, which means they have both male and female flowers on the same tree. The fruit is a black-blue, ovoid stone fruit, about 10 mm long with a thin, oily, bitter-to-sour tasting flesh and very popular with small bird species. There are from one to three fruits together on a long slender stalk. They are a valuable energy food for birds, especially the American robin. "Nyssa sylvatica" forms
