Ash for bonsai

The common Ash, Fraxinus excelsior, is a fast growing tree species related to olives. Young trees have a smooth bark which turns crusty with age. The species can be easily recognized by the black buds.

Leaves are opposite and compound, up to 30cm long consisting of up to 15 leaflets. This, in combination with a fairly coarse growth habit make this species less desirable for bonsai.
