Pink lady slipper (Cypripedium acaule)

The roots of the pink lady slipper (Cypripedium acaule) engage in a symbiotic relationship with the fungus Rhizoctonia. This fungus is crucial for the orchid's lifecycle, particularly in seed germination, as it supplies the necessary nutrients that the seeds themselves lack. Additionally, Rhizoctonia continues to support the plant by providing essential nutrients throughout its growth.
