This is an exceedingly ornamental and at the same time a most interesting species of the genus. It is remarkable in having the hollow stems and 5 celled ovary of Leycesteria, associated with a long spurred corolla (calcaratus: spurred), which is only represented by a more or less pronounced gibbosity in other species. It was discovered by Augustine Henry in Yunnan near Mengtze. In Roy Lancasters garden (UK) plants are grown from seed collected in 1994 by the Japanese botanist and plant explorer Mikinori Ogisu from Mount Omei in Sichuan. The flowers opening cream, becoming apricot and finally burnt orange, as in L. hildebrandiana.
Not widely in cultivation, but it´s merit your attention.
