About

Buddleja fallowiana var. alba Sabourin is a white-flowered variety of B. fallowiana endemic to Yunnan in western China, where it grows in open woodland, along forest edges and watercourses. The shrub was considered superior to the lavender-blue flowered B. fallowiana by Bean, who thought it one of the most attractive of all buddlejas.

Introduced to cultivation as seed sent to England in 1925 by Forrest, the variety was named by Sabourin. However its status was challenged by Leeuwenberg, who considered its different flower colour and smaller size insufficient to justify its distinction as a variety, and sank it as simply B. fallowiana.

How to grow it

Somewhat tender, var. alba is better grown against a wall. However, if cut to the ground by frost, it will grow again from the base. Growth is significantly slower than that of B. davidii, Bean considering the species more closely allied to B. nivea. Hardiness: RHS H5, USDA zones 8–9.
