Yet another plant featured recently that lacks an English common name, Maianthemum purpureum is native to the Himalayas (see Flora of China account). The genus is widespread throughout the temperate Northern Hemisphere, but also has some subtropical montane representatives in both southeast Asia and Central America (from the description of the genus in this paper).

The photo you have as Maianthemum purpureum is M. oleraceum, but surely you know that by now?
