Zuisho Japanese white pine
IntermediatePinus parviflora 'Zuisho'
A leading yatsubusa (dwarf, densely budding) cultivar of Japanese white pine, propagated by cuttings, grafts and layers from a single mutant branch. Its foliage is fine and compact, yet it grows quickly for a white pine, so a tree takes shape fast.
About
Zuisho is one of the yatsubusa cultivars of Japanese white pine (Pinus parviflora). Yatsubusa describes plants whose shoots and needles are smaller and more densely packed than the ordinary form, and Zuisho and Kokonoe are the best-known examples in white pine. According to the Japan Zuisho Club, Zuisho arose as a mutation on a white pine and has been propagated from that one branch by cuttings, grafts and layering; the first cutting from the original tree dates from 1954, and even the oldest surviving trees are under 70 years old. A bonsai magazine describes it as growing remarkably fast for a white pine, reaching a finished tree from a young plant within a few decades, earning it the nickname 'dream tree of the Showa era'. Its fine, dense yatsubusa foliage and vigorous growth are what set it apart. Little is documented about its exact needle length or colour, and seedlings do not reliably inherit the parent's traits, so buyers should check that a plant was vegetatively propagated. Care follows ordinary white pine: outdoors in sun and good airflow, kept on the dry side. Specialist bonsai nurseries sell everything from starter plants to large finished trees.
