Scots or Wych elm, Ulmus glabra
Ulmus, the true Elms.
Pretty much any of the Elms that you come across will perform well as bonsai. It is not always easy to settle on the exact species due to the fact that they hybridise so readily.
The common UK species are U. procera , english elm, U. carpinifolia, Smooth leaved elm, U. glabra, Scots or Wych elm. Several others classed as species are quite region specific although with cultivation comes the likelihood of planting in almost any area.
In any case they are all hardy and grow well in a wide range of conditions. They respond particularly well to most bonsai techniques, happy living in pots, react really well to pruning making branches quick to grow and ramify and consequently make creating the desired beautiful winter image of deciduous species just about as easy as it can be.
This example is without doubt the elm familiar in the northern parts of the UK , the Scots or Wych elm, Ulmus glabra. This locally created bonsai will have originated from wild collected material and is really beginning to take shape nicely. The quite complex branch structure already gives it a mature image. The tree is 75cm. in height with a branch span of 66cm. Across the base of the trunk the measurement is 8cm. The Korean ceramic pot is 42x32x8cm. A nice deciduous bonsai to add to a collection.
