Abstract
Since 1993, mountain lady’s slipper (Cypripedium montanum Douglas ex Lindley [Orchidaceae]) has been successfully established in the forest of the Grande Ronde Overlook Wildflower Institute Serving Ecological Restoration (GROWISER). Emergence in the field generally requires 2 to 3 y and seems to be associated with the level of tree canopy and decomposing forest litter. More plants appear to be established when seeds are mixed with a carrier such as forest soil, sugar, or cracked corn prior to scattering. Plots have been established annually since late autumn 1998 to investigate seeding techniques and the orchid’s life cycle, particularly time until flowering.
