The part of ATP, for me, is getting to see the photos. Glad you like this one. The common name is misleading in that this plant is in the mint family and not a Buddleja at all. The genus rostrinucula contains just 2 species, both endemic to central China (Shaanxi to Sichuan). Rostrinucula plants are deciduous shrubs/perennials in the mint family that bear a passing resemblance to buddleia, in both leaf and flower form.
