Buddleja/ Buddleia fallowiana | Fallowiana Butterfly Bush ‘Alba’ (white form)
A deciduous shrub native to Yunnan, Sichuan, and Xizang, China.
Fallowiana or Fallows Butterfly Bush (named after George Fallow), also sometimes called White-flowered Chinese Butterfly Bush, has arching branches bearing lance-shaped, heavily-felted, whitish, silvery-green leaves that are soft to the touch, and panicles of highly-fragrant creamy-white flowers with large yellow-orange eyes, blooming from late summer into early fall. The aroma is similar to that of the Buddleja davidii, but even sweeter. The flowers are similar too, but are a little bit smaller. The structure is similar, but fallowiana is slower growing, shorter, and a little more compact.
HOWEVER, seeds collected from Fallowiana Alba grow into plants that do NOT have white flowers, but rather a purple perwinkle blue form.
Naturally grows in open woodland, forest edges, and stream banks in mountainous elevations. In the garden, it grows best in fertile, free-draining soil in full sun. Will tolerate some shade. Goes mostly deciduous in winter and may die back to the ground in extremely cold winters. Site in a sheltered spot if possible. For the healthiest growth it is recommended to soft-prune in late autumn and then hard prune down to your knees in April.
B. fallowiana was one of the parents used to create the famous Buddleja hybrid, B. ‘Lochinch’.
