Platanthera hyperborea
Encyclopedia
Description: Platanthera hyperborea is a green to yellowish-green perennial, monocot herb growing 10–90 cm.
Similar species: Platanthera hyperborea 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.
Habitat: 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.
Flowering dates: June 15-July 25.
Pollination: Some varieties or populations are pollinated by bumblebees and moths (Catling & Catling 1989), many (if not all) are also autogamous (Catling 1983a).
