Buddleja madagascariensis

''Buddleja madagascariensis'', also known as smokebush, is an evergreen shrub or climbing vine endemic to Madagascar, where it grows amongst scrub on mountain slopes to elevations of 600–2,000 metres . The species was first named and described by Lamarck in 1792, and introduced to cultivation in 1827. Popular around the world as an ornamental, ''B. madagascariensis'' has widely naturalized and is now classified as an invasive species in Hawaii and New Zealand ; it can also be found growing wild in southern China, and along the Mediterranean coast of France.

The shrub was accorded the Award of Garden Merit by the Royal Horticultural Society in 2002.
