|The common alder (which is also known as the black alder) has always been associated with water. It loves damp, waterlogged ground close to river and bogs. It is one of the few leafy deciduous trees which use cones to reproduce. It’s wood is waterproof and is used to make anything from boats to wooden clogs. It forms the foundations for much of the buildings of Venice in Italy.||Origin: All of Europe, extending to western Asia and south to North Africa
Shape: Broadly conical
Leaf Shape: Obovate
The alder produces catkins in early spring before the leaves appear. It has cones which begin to emerge in summer and remain on the tree for the whole of autumn and winter.
Potential as a bonsai
It is a fast growing tree which develops a very rugged looking trunk. It is fairly easy to train but needs to be made into a large bonsai because the leaves do not reduce in size easily.
