Goldencup St. John's wort (Hypericum patulum) is native to China, coming to Japan in around 1760 and can now be found across the country. It produces bright yellow flowers from May to July, which resemble the flowers of Chinese St. John's wort (Hypericum monogynum) but can be easily distinguished by the length of stamens. The stamens of Hypericum patulum are much longer than those of Hypericum monogynum.
