Native to China and the Himalayas, this Tibetan bamboo is a stately & highly decorative ornamental. In more sun, culms turn maroon to almost black w/delicate purplish-green leaves. In summer shade, the culms remain rich green w/white node rings. Culms get darker, sometimes almost black, in winter. Grows to 15-20' tall and Ÿ"-1œ" in diameter depending on origin. Can tolerate temperatures down to only 15 degrees, and likes a half-day of sun. Shoots in the spring & fall.
