Thamnocalamus crassinodus is a deep-shade, clumping bamboo with a gracefully arching, open airy habit. Its petite, feather-like leaves drape from burgundy branches and are reminiscent of brush paintings of bamboo. The new canes emerge blue-green, maturing to a deep burgundy red or purple with light sun exposure, but they need protection from afternoon sun to prevent leaf curl. This rare and beautiful bamboo also has swollen nodes, which give it a rather unique appearance.
Clumping Bamboo was collected from the high mountains of the Himalayas in 1991, and for several years grown in the US as Thamnocalamus aristatus. It has since then been identified as T. crassinodus. Although grown in the UK for many years, this dramatic and dainty bamboo is still a novelty in western gardens.
T. crassinodus is happiest in full shade in moist, organic, rich, slightly acidic soil. It does best in cool climates, makes an excellent interior plant for moderate light, and can reach a height of 18 to 20 feet. Zones 8-9.
