About
Platanthera clavellata, commonly known as the club-spur orchid or small green wood orchid, is a terrestrial orchid of North America.
Where it grows
The plant will grow in moist and acidic soil and requires partial shade. It can grow in areas like moist meadows, bogs, swamps or forested seeps. Its spread is further limited as seeds cannot germinate by themselves and instead require a specific soil fungus to be present. One known soil fungus that associates with P. clavellata is Epulorhiza inquilina.
