Thunderhead Japanese Black Pine
Pinus thunbergia 'Thunderhead' (Thunderhead Japanese Black Pine)
Pinus thunbergii (Japanese Black Pine, Kuromatsu) A wonderfully hardy, tough tree that is native to the sea cliffs of Japan, enduring gale winds and salt spray. In Japan, gardeners grow and shape this tree with bamboo and twine, lashing the branches to form broad flat foliage areas to recreate the look of the twisted and tortured cliff dwellers. A twice yearly pruning will create flat pads of very dense short branches and completely control the size and shape of this tree. In June (timing varies with climate) remove all the new candles that are longer than one inch. Many new shorter candles will form a whorl of short branches. In November reduce this whorl of branches to a flat forked branch. In this manner the 3 inch green needles may be reduced to 2 or even 1 inch. Some of the oldest living bonsai plants are Japanese Black Pine. It has been a traditional bonsai plant for hundreds of years.
