Arakawa
‘Arakawa’ is a green Japanese maple known for its very rough, fissured, corky bark, decorative all year round. The foliage is green through the season, then turns golden yellow to orange-red in autumn. This cultivar is widely used for bonsai, precisely because of the character of its trunk and bark.
Character & interest
The main appeal is the bark: it gradually becomes bumpy, fissured and corky, with a very expressive look on mature wood. The foliage remains classic, naturally highlighting the trunk.
Colours
-
Spring : fresh green.
-
Summer : rich green.
-
Autumn : golden yellow to orange-red (depending on exposure and the season).
Habit & vigour
Upright habit, good vigor. The bark often takes a few years to develop its relief (often from 3–5 years on maturing wood).
Indicative size
Typical range: 3 to 4 m over about ten years, then a small tree that can reach 6 to 8 m in the long term (variable with conditions and training).
Exposure
Tolerates full sun in most regions, but the best compromise is often gentle sun / bright partial shade, with protection from harsh afternoon sun in hot situations.
Origin & history
A Japanese name: “Arakawa” means “rough bark”, a direct reference to its highly textured trunk.
