[4] The shrub was introduced to the UK by Lord Wigram, who received it from the Lloyd Botanic Garden in Darjeeling[5] as Buddleja hastata Prain, ex C. Marquand in 1931.

[6] Buddleja tibetica is a deciduous shrub of very sparse habit, growing to < 3 m high, more in diameter.

The faintly scented flowers form compact sessile or subsessile clusters, initially dark purple, they rapidly turn pale on opening, ultimately becoming white.

The distinctive leaves are < 10 cm long, and broadly lanceolate, though there is considerable variation in both size and shape; the upper surface covered with a tomentum which persists for several months, bestowing a greyish-white bloom.

Still very rare in cultivation, the shrub was propagated in 2007 by Peter Moore of the Longstock Park Nursery, NCCPG National Collection holders, near Stockbridge in Hampshire.
