Tiger Bamboo, as it is often called in Asia, is one of our most beautiful bamboos. Like other forms of Phyllostachys nigra, the culms are green when they first emerge from the ground. Within months they acquire the darkish-brown patches that give this bamboo such a distinctive appearance. For us, Tiger bamboo grows taller and thicker than black bamboo. The culms of this bamboo are used extensively in Japanese woodworking. They are prized for use in teahouses. Other bamboo are treated with acid to achieve the same look.
