Description

''Buddleja albiflora'' grows to a height of 4 m in the wild, the branches erect and glabrous. The leaves are narrow lanceolate, with a long-tapered point and wedge-shaped base, 10–22 cm long by 1–6 cm wide, toothed and dark-green, glabrous above in maturity, but covered beneath with a fine silvery-grey felt. The shrub is similar to ''B. davidii'', but has rounded stems, as opposed to the four-angled of the latter. Despite its specific name, the fragrant flowers are actually pale lilac with orange centres, borne as slender panicles 20–45 cm long by 5 cm wide at the base; they are considered inferior to those of ''B. davidii'' and thus the plant is comparatively rare in cultivation.Leeuwenberg, A.
