Platanthera dilatata var. dilatata var. dilatata
The tall white bog orchid is a native North American terrestrial orchid best suited to wet, acidic, humus-rich soils in cool climates and is not recommended for typical home gardens. It requires stable bog or fen-like conditions with consistent moisture and is extremely sensitive to soil disturbance or transplanting. Purchase only ethically propagated specimens and recreate its native moist meadow environment as closely as possible.
