Establishment: Seed is collected by hand from locally native plants within the eastern central Upper Peninsula. The plant is found in rich deciduous woods often on hillsides, ranging from upland beech-maple and hemlock hardwoods to low floodplain woods and streamside thickets.

Gradually increase light and temperature in the spring. * hydrophilic; germination is hypogeal
