This tiny orchid has a circumboreal distribution and is most often found in the moist forest understory hiding among the mosses. Twayblade orchids are fairly common in the Pacific Northwest but are usually overlooked due to their size (rarely more than a few inches tall) and unremarkable coloration. We have five species of Twayblade in the PNW – one of which is endangered.
