Platanthera hyperborea is a green to yellowish-green perennial, orchid herb growing 10–90 cm. It is similar to Platanthera dilatata, the two hybridize freely, and produce intermediate offspring; the labellum is strongly dilated at the base in P. dilatata, and less so in P. hyperborea.

Platanthera hyperborea will grow in full sun to full shade and in almost any moist to wet, open to semi-open habitat from acidic sphagnum bogs to highly neutral fens. It flowers from June 15 to July 25. Some varieties or populations are pollinated by bumblebees and moths (Catling & Catling 1989), many (if not all) are also autogamous (Catling 1983a).
