Platanthera flava is a species of pale-flowered orchid. It has from 10-40 flowers in an inflorescence. In the north of its range, in Canada, this species is particularly associated with shorelines of lakes and rivers, in the seasonally flooded zone.[1] In Nova Scotia, it occurs in wet meadows on seasonally flooded shorelines with rare shoreline species such as Plymouth Gentian.[2] In the south, such as in Texas, it is found in wet savannas and flatwoods.[3] The shoreline habitats of the north are maintained by ice scour, while in the south, the flatwoods are maintained by recurring fire. Hence, it appears that this species depends upon recurring natural disturbance to maintain open sunny conditions.
