Carpinus betulus 'Frans Fontaine'

The narrowest Carpinus betulus cultivar. At a height of 10 m the tree is only 3 m wide. Young twigs are grey: older branches and the trunk are dark grey and remarkably smooth. The leaves are a fresh colour of green in the spring and retain that colour throughout the summer. Since 'Frans Fontaine' only bears male flowers, the tree does not produce any fruit. It's a good avenue or street tree.
