This species was introduced into cultivation by Jim Roberts in 2011 who found it on a trip to China.  It was originally distributed as Petrocosmea JR 2011 sp. ‘A’, and later as Petrocosmea coerulea.  P. Xlongianthera is a natural hybrid described formally in 2011, and Mr. Roberts’ plant was later identified as belonging to this group. There is some uncertainty about this identification.

• A plant exhibited in the 2021 virtual show of the Gesneriad Society; this specimen is somewhat different-looking than the clone exhibited above; this may be a function of natural variation, or there may be some taxonomic confusion
