Buddleja asiatica, also known as dogtail,[4] is a species of flowering plant in the figwort family, Scrophulariaceae.[2][5] It grows in open woodland at elevations < 2,800 m either as understorey scrub, or as a small tree.[6] 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.[7][8] It is highly invasive in Hawaii, Guam, and the Northern Mariana Islands.[9]
Buddleja asiatica can grow < 7 m tall in the wild. The leaves are usually narrowly lanceolate to ovoid, < 30 cm long, attached by petioles 15 mm long, to branches round in section. The sweetly scented flowers are usually white, occasionally pale violet, and borne in late winter at the ends of the long, lax branches in slender panicles, the size of which can vary widely according to source.[6] Ploidy: 2n = 38 (diploid).[10]
