Buddleja asiatica is a tender deciduous shrub endemic to a vast area of the East Indies, including India, Nepal, Bangladesh, China, ******, Burma, Thailand, Laos, Cambodia, Vietnam, Malaysia, New Guinea, and the Philippines, growing in open woodland at elevations < 2,800 m either as understorey scrub, or as a small tree. First described by Loureiro in 1790, B. asiatica was introduced to the UK in 1874, and accorded the RHS Award of Garden Merit (record 675) in 1993.
