The genus Cotoneaster contains many common garden shrubs and that in itself should indicate that it is a plant that is very comfortable in UK conditions making it very easy to keep, grow and develop as a bonsai subject.
The Cotoneaster species range from prostrate, creeping shrubs, often these will have very small leaves making them great for particularly the smaller size classes of bonsai, to small trees with perhaps larger leaves. It also includes deciduous and evergreen species. A particular attraction of all the Cotoneasters is that they have very small white or pink tinged flowers followed by mainly red berries. Good autumn colour is also an attractive feature. All in all good bonsai subjects.
At 33cm. high this example is in the chuhin size class of bonsai. The trunk, which is 4cm. across at the base, features the flowing movement of the informal upright style. There is already the makings of a good branch structure, which is about 30cm. wide, with both primary and secondary branching established. The proportions are already good so all that it required is more complex ramification which is an exercise in growing and pruning. For that reason the previous owner was growing the tree in a basket type trainer, 23x13cm., to maintain vigorous roots in the well aerated growing medium. The close up shows the canopy covered with flower buds. Really the bonsai could be transferred to a suitable ceramic pot next spring.
