Native of S.W. Szechwan, N.W. Yunnan, and S.E. Tibet; discovered by Forrest in 1913 on the Chungtien plateau and introduced by him. He evidendy thought highly of this species, which he dedicated to his wife, but in cultivation it is unremarkable in its flowers and worth growing only for its handsome foliage, which is steely blue when young. It is perfectly hardy.
