Native of Mt Victoria, a mountain just over 10,000 ft high in the Southern Chin Hills, south-west Burma. It was discovered there by Lady Wheeler Cuffe and introduced by her to the Glasnevin Botanic Garden, where it first flowered in May 1914. Although not hardy enough for cultivation outdoors near London, it succeeds in several gardens on the west coast of Scotland.
