Platanthera chlorantha is related to the Mediterranean countries, the countries by the Atlantic, and be found from West Asia, Sicily and north to the coast of central Norway. In Norway we find the spread and fairly common in eastern Hedmark in the north and south and west around the coast of Nord-Trøndelag.
Platanthera chlorantha resembles the subspecies Platanthera bifolia, but it is more rough and rugged. One bottom leaf is greater than the second. The flowers seem more green-whites than among subspecies of P. bifolia. The flowers have spore which is long and thickest in the middle. It is considered as something lime demanding and thrives in open woods, grazing land and hayfields. It can be found in the same habitat as P. bifolia ssp. latifolia and is found up to 530 m. Sauda in Rogaland.
It is easy to see the difference from the subspecies of P. bifolia because the flowers have a greater distance between their pollination ceremonies that are not parallel but divergent. The other two subspecies P. bifolia have pollination ceremonies sitting parallel and closer.
