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.
