Buddleja myriantha is a species endemic to upper Burma and western China, including Tibet, where it grows along forest edges, thickets and streams at altitudes of 2,000 – 3,200 m.[1] The species was first described and named by Diels in 1912.

[2] Buddleja myriantha is deciduous shrub growing 1 – 3 m in height, with subquadrangular, glabrescent branchlets bearing opposite leaves, 5 – 20 cm long by 0.9 – 6 cm wide, narrowly elliptic, acuminate at the apex, cuneate or decurrent at the base, the margins serrate or entire.

The colour of the flowers ranges from purple through violet, to white.

A specimen is grown at the Royal Botanic Gardens Edinburgh.

[4] The shrub is purportedly in commerce in the UK and beyond, although the plants in question are not believed to be B. myriantha.
