Chusquea culeou

Chusquea culeou, the Chilean bamboo, () is a species of flowering plant in the grass family Poaceae. An evergreen bamboo native to South America, unlike most species within the genus "Chusquea", it is frost-tolerant and thus widely cultivated in temperate regions.
Distribution.
It is native to the Valdivian rainforests, humid temperate forests of Chile and southwestern Argentina. Chusquea culeou is a keystone species which can control patterns of forest dynamics by impeding regeneration of tree species.
