About

Carpinus kawakamii is a medium-sized deciduous tree, typically growing to a height of 9 meters (30 feet) at maturity. Its bark is dark grey on older sections, while younger branches exhibit a brownish-grey hue. In regions with mild climates, particularly in the southwestern part of England, it may retain its leaves throughout the year. In spring, the foliage begins as reddish-green, transitioning to green during summer, and then displaying a vivid orange-red in the fall. This species produces separate male and female catkins on the same tree, which appear from May to June. Following pollination, the female flowers develop into clusters resembling hops in late summer to autumn, containing winged seeds that are dispersed by the wind when they reach maturity.
