The Trident maple, Acer buergeranum, is one the classic bonsai species that we see from Japan.
. Although not at all familiar in our gardens and landscape it was in fact introduced to this country in about 1890. The tree authorities put the species as originating in East China and Korea.
It is a species which is very happy in UK conditions making it relatively easy to keep and to develop. In fact it will be very vigorous in the correct conditions making it quick to bring to a desired shape. As you would expect from one of the classic deciduous bonsai species it responds well to living in a pot and to regular pruning. Like all Maples it is quite brittle so care must be taken if the need to apply wire occurs. The only other thing really to bear in mind is that it will benefit from a bit of protection from low winter temperatures.
At 45 cm. in height this tree is in the chuhin size category of bonsai. It will have been imported from the Far East some years ago, possibly Korea. The well developed branching spreads to 40 cm. and within that structure you have good primary and secondary branching. The fine ramification could certainly be improved and this would be by simple growing and pruning. The leaves are just emerging and are typically nice and small. It is potted in a nice quality Japanese oval glazed ceramic.
