Fargesia robusta

Fargesia robusta is a species of clumping bamboo in the family Poaceae, native to Sichuan, China. Typically but reaching, and with a narrow growth form, it has gained the Royal Horticultural Society's Award of [Garden Merit] as an ornamental. A number of cultivars are commercially available, including 'Campbell', 'Pingwu', 'Wenchuan', and 'Wolong'.
It is a food source for giant pandas but grows at too low an elevation for them to exploit, unless there has been a die-off of their usual species. It is a member of the Fargesia spathacea species complex, and may not be a distinct species.
