Upright orchid growing from a bulbous caudex and producing a spikelike inflorescence of up to 100 fragrant, honey-scented flowers that are whiter than those of other Platanthera, but sometimes green-tinged or veined.


Coniferous forests and other habitats in coastal and inland mountain ranges within 150 km of the coast.


It is native to western North America from Alaska to the San Francisco Bay Area.


The status of this species in the wild is difficult to determine because most populations are small and may produce flowers only rarely.
