Chamisso's Orchid, Platanthera chorisiana, is one of our smallest native orchids and very hard to find. In our area these grow in a boggy area among the sedges and at the edge of the bushes and shrubs. Both plant and flowers are the same green as the grasses and sedges, too. When I went to visit them they were finished blooming and so I've also included an older photo of the species. They were 15 cm tall or less and the tiny flowers are less than 1 cm and do not open widely. It grows at high elevations or northern latitudes.
