These have been top-pruned, but will still take a few years development to become good individual tree specimens. They can make a nice group planting. Trident Maple - Acer buergerianum AC3 on left, AC7 on right. On far right an example of a mature trident maple bonsai. Excellent bonsai tree.
Leaves reduce in size with pruning, trunks develop size and taper rapidly.
They are particularly good at developing good swelled bases with good rootage at a young age. These have all been pruned back each year to encourage branching. Will also make an excellent group planting. Responds well to pruning, and leaves reduce in size when potted for bonsai. Golden yellow leaves in fall.
