nigra or Black Bamboo is an upright,
evergreen “running” bamboo, the only
species in the genus with black culms,
or canes, which under ideal conditions
can grow to 2” in diameter.

The
culms emerge green and turn black within
the first 2 years. The internodal culms
have prominent vertical grooves above
typically two lateral branches, and the
culm sheaths arising at the nodes have
distinctive wavy blades and prominent
auricles, or ear shaped protrusions on
either side of the sheath base.
The dark appearance of the culms can be
emphasized by removing the side shoots
and leaves up to about 4’ from the
ground. P. nigra is a much less
aggressive spreader than the other
members of the genus.
It can be contained by underground
barriers, or annual spring trenching
down to rhizome level to cut off stem
tips. Surrounding the planting area
with a trench of sand 1 foot deep and 1
foot wide makes removal of traveling
rhizomes much easier. P. nigra can be
grown in large containers, with regular
watering and feeding and periodic
dividing. P. nigra produces a dark
wood of high quality which is prized by
craftsman for furniture and other items. |
