Buddleja japonica is a deciduous shrub in the family Scrophulariaceae.[1][2] It is native to Honshu and Shikoku, Japan, where it grows on mountain slopes amid scrub.[3] The shrub was named and described by Hemsley in 1889, and introduced to Western cultivation in 1896.[4]
Buddleja japonica grows to < 1.5 m in height in the wild, open in habit and sparsely branched. The branches are tetragonous and winged. The leaves are narrowly lanceolate, < 20 cm long by < 5 cm wide, the upper surface dark green and glabrous, the underside tawny felted. The flowers form dense, drooping terminal panicles < 20 cm long, usually pale lilac in colour, from July to October. Overall, the species is considered of little horticultural merit and is also comparatively short-lived.[5] Ploidy: 2n = 38.[6]
