Wroshyr trees were gigantic trees that grew on the planet Kashyyyk, homeworld of the Wookiee species. The native Wookiees lived in homes built in the wroshyr trees of Kashyyyk, and many of their weapons were whittled from wroshyr wood. There existed over 1000 varieties of wroshyr trees adapted to growing everywhere on Kashyyyk save for the poles. Those who grew in the deep forests reached several kilometers in height, while the tropical variety found in coastal regions only averaged 300 to 400 meters.
