From Malaysia and Thailand. A vining bamboo with rough culms. The culms actually have a texture that is angled in one direction - downward. If you rub a culm from the top down, there is minimal resistance. Reverse direction and you can feel the grip. This evolutionary feature allows the culms to attach to plants and trees. There are also small secondary branches that develop into spikelets, also for grabbing and attachment purposes. Will grow 30' vining culms up to 1/2" in diameter. Minimum temp. 33 degrees F.
