The Palegreen Orchid, Platanthera flava, is a peat loving, easy-to-grow, summer blooming bog orchid. It has a large, green cylindrical cluster of 30-75+ dainty flowers with showy, fringed lips and long spurs. It is a mid-to-late summer bloomer, and flowers last for a month or more. Leaves are long and lanceolate, reducing to small bracts with the flower cluster. Flower spikes are tall and benefit from staking, and protection from the wind. Best flowering occurs with plants in full sun, shade tends to reduce flower size and abundance. It grows somewhat smaller than other fringe orchids. It is a bog plant which grows in open, acidic bogs with sphagnum moss, but is adaptable to drier, upland conditions, as long as the soil remains damp during flowering. It does best in damp conditions, and frequently sends out a stolon budding small plants. It is an adaptable and vigorous grower. Seeds are very fine and can be a challenge to germinate. It is winter hardy, and should be protected from rodents during dormancy. Mulch with 4+" of pine needles in the Fall. Leave at least a 1" of needles after spring cleanup. The rhizomes can be stored in damp sphagnum at 35°F (2°C) in a refrigerator for 3 or 4 months. Water with rain/distilled water, they are sensitive to mineral buildup. It spreads nicely and grows well among pitcher plants. It is a late summer star in the bog garden, and makes good cut flowers.
