Buddleja davidii var. superba is a variety of butterfly bush, a large shrub prized for its long, fragrant violet-purple flower spikes that attract butterflies. Note that the sources say it is not known to remain in cultivation, and it is treated as a synonym of the wider species by several authorities, so most gardens grow standard Buddleja davidii cultivars instead.

About
Buddleja davidii var. superba is endemic to the Yunnan province of western China. The taxonomy of the plant and the other five davidii varieties has been challenged in recent years. Leeuwenberg sank them all as synonyms, considering them to be within the natural variation of a species, a treatment adopted in the Flora of China published in 1996, and also upheld by both the Plants of the World Online database and the International Dendrology Society's Trees and Shrubs Online website.
