Buddleja albiflora
''Buddleja albiflora'' is a deciduous shrub native to the mountains of central China, where it grows on shrub-clad slopes at altitudes of between 1,000 and 2,000 m. Named rather carelessly by Hemsley, the species was discovered by Henry, and introduced to western cultivation by Wilson in 1900.〔Bean, W. J. (1981). ''Trees and shrubs hardy in Great Britain'', 7th edition. Murray, London〕
==Description==
''B. 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.
