Characteristics of Phyllostachys Bambusoides 'Giant Japanese Timber'
A giant bamboo species that is slow to mature but makes a beautiful walk through grove and thick privacy bamboo screen while waiting for it to size up. Known for excellent wood qualities.
Phyllostachys Bambusoides 'Giant Japanese Timber' is the mother form. It looks the same as 'Crookstem' except larger in subtropical climates and without the very slight bend of the cane on some specimens. This giant is slow to mature. In our experience, we find it best suited for climate zones 7 and 8. Only under ideal growing conditions of great soil, full sun will it reach mature sizes with thick culm (cane) walls. It does not need a cool dormant period like most other temperate species.
'Giant Japanese Timber' produces a beautiful walk through grove and thick privacy bamboo screen while waiting for it to size up.
In USDA Climate Zone 7 and 8 expect mature size canes to be over 70 feet in height.
The only large groves I have seen of the 'Giant Japanese Timber' bamboo have been in climate zones 7 and 8. Not as cold hardy as the 'Slender Crookstem'. It gets top damage here in zone 7 when temperatures drop into the low twenties. Completely defoliates at around 5 to 10 degrees F. Canes die from 0 to -5 degrees F.
'Giant Japanese Timber' flowered during the 70's and into the early 80's. Mature groves are now hard to find and some sporadic flowering is still being reported. Some clones of this species are reported to be in flower intermittently without lost of the grove. Our clones are not in flower and we would not sell any that was.
