Hokkaido / June 7, 2022 It was cloudy, but occasionally the sun was shining.
This species, discovered in a wetland in Hokkaido, can still be considered a newly recognized species of violet. It was reportedly described as a new species in a scientific paper in 1996. I would definitely like to visit its natural habitat someday. ??Apparently, its flowering season is in June. (Note: Visited in 2022)
