Native of Hupeh and Szechwan, China; named by Maximowicz in 1880, introduced to cultivation by Wilson in 1908. At Kew it has to be grown in pots and given greenhouse treatment from October onwards, as it is valuable in flowering for three months in midwinter. Hardy in Cornwall and similar mild localities, where it should be welcome on account of the season at which its delicate lilac, fragrant blossoms open. It is closely allied to B. heliophila, but in that species the leaves are almost sessile and the corollas up to 12 in. long.
