Borinda yunnanensis (= Fargesia yunnanensis)
This beautiful and vigorous bamboo is variously placed in the genera Fargesia, Yushania, Borinda and Sinarundinaria. It is native to montane forests between 1700 and 2500 m (5600 and 8200 ft.) in southwestern Sichuan and in Yunnan, China. Its robust, clustering culms can reach a height of 7 or 10 m (23 or 33 ft.) and a diameter of up to 6 cm (2.5 in.) and have persistent, leathery sheaths with stunning purple stripes. The leaves are long, narrow and deep green. A fabulous and easy ornamental for cool and warm temperate regions. It is unharmed by moderate to severe freezes. The young shooths are edible and of excellent quality.
