Carpinus japonica Japanese Hornbeam

Betulaceae

Carpinus japonica Japanese Hornbeam

A large bush-like form gives way to a decorative tree with a fine vase-shaped manner of growth that later becomes broader. Its manner of growth resembles that of C. betulus, but there is a clear difference in that the bark of C. japonica is light grey-brown and flakes off in small scales. The leaves are relatively small and tinted reddish when they first appear. The leaf has a sharply double serrated edge and the leaf top tapers to a point. The underside of the leaf is slightly hairy. The nutlets are in short squat clusters. Because there are no separate bracts the clusters look like hops and are thus very decorative. They grow to a length of approx. 6 cm. The autumn colour is golden yellow. Root growth is relatively close to the surface. The rotted leaves are good soil improvers.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
