Dendrocalamus sinicus, the dragon bamboo, is a gigantic clumping bamboo native to Yunnan Province of China and to Laos. It has the largest culms of any known species of bamboo; up to 14.5inches wide with culm walls up to 2.3inches thick[1] and the culm up to 151abbr=offNaNabbr=off in height. Each culm can weigh up to 990lb apiece.[2] [3] [4] A plant eventually consists of about one hundred culms. This species was unknown to science prior to 1980, although well known to the citizens of Yunnan and Laos for centuries.
