Abstract: ‘Zijingzhu’is a new bamboo cultivar selected from the wild variation of Qiongzhuea montigena Yi in Wumeng Mountain National Nature Reserve in Yunnan Province. The key difference between‘Zijingzhu’and the wild Qiongzhuea montigena is that the internodes of the‘Zijingzhu’ bamboo shoots and culm sheathes are purple. The culm sheaths gradually turn into light purple and fall off with the growth of the bamboo，then the internodes will develop into dark purple with high ornamental value.
