Bambusa arundinacea - Thorny Bamboo

From South China, this tall 100' bamboo is a large, lush ornamental but also is used in the tropics as a timber source and for paper pulp. The young stem sprouts are edible. Must be kept quite warm. Lives up to its name by creating an impenetrable wall of long hooked thorny branches. Once established it will replace any form of fencing.
