Buddleja japonica is a deciduous shrub native to Honshu and Shikoku, Japan, where it grows on mountain slopes amid scrub.[1] The shrub was named and described by Hemsley in 1889, and introduced to Western cultivation in 1896.[2]

Description

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.[3] Ploidy: 2n = 38.[4]
Cultivation

In the UK a specimen is grown as part of the NCCPG national buddleja collection at Longstock Park Nursery, near Stockbridge, Hampshire. Hardiness: USDA zones 8–9.[2]
Varieties

Buddleja japonica var. insignis (Carr.) E. H. Wilson. A plant with a denser habit and more brightly coloured flowers.[3] In the absence of any living specimens or preserved material, the plant was considered probably a hybrid of B. japonica and B. lindleyana by Leeuwenberg [5]
