Japanese Maple 'Bi Ho' Overview

Acer palmatum 'Bi Ho' is a bushy deciduous shrub that forms a small, standard tree. It produces bright yellow-green leaves flushed with salmon pink in spring, through to a yellow-green colour in summer, before turning stunning shades of orange-yellow in autumn. Commonly known by the names Japanese Maple 'Bi Ho' and Golden Bark Japanese Maple, it is occasionally sold with the spelling 'Bihou' or 'Bi Hou'. It produces golden-yellow and orange stems that in winter, provide colour similar to that of a Cornus. Its mature height of 2m after 10 years makes it a good choice to include in smaller gardens or for larger containers. It has insignificant flowers in spring followed by winged fruits in summer. It likes a sheltered position in partial shade. Leaf colour will be more impressive when grown in a slightly shaded area, but it will tolerate full sun if soil conditions are moist enough. Otherwise, leaf scorch may occur. It prefers soil that is on the acid, rather than the alkaline side, which is moist but well-drained. So keep well watered during dry spells (and regularly water newly planted trees). Additional plant feed may be required for potted or container-grown specimens. Acers can also benefit from spring and/or winter mulching with a helping of ericaceous material such as pine needles or chopped bracken. Little to no pruning is recommended; however, removing dead or unwanted branches can be done in late autumn to midwinter. A low-maintenance, architectural plant, Acer palmatum 'Bi Ho' is a welcome addition to many garden styles, including courtyards, rock gardens and Japanese style gardens.
