Plant Profile: Cypripedium acaule

The Pink Lady Slipper is a native orchid that thrives in highly acidic soils, favoring partial shade and well-drained slopes. Typically found in pine forests, it often grows in large clusters, particularly in the mountainous regions of North Carolina. This plant is notoriously challenging to transplant and cultivate, making it best suited to its natural environment, which consists of dry to mesic, acidic forests and woodlands, frequently located beneath pines, other conifers, and oak trees.

For germination and growth, the seeds depend on a specific type of Rhizoctonia fungus. As the Pink Lady Slipper develops, it forms a symbiotic relationship with this fungus. The plant features two basal leaves with distinct parallel veins, from which a single stalk rises, culminating in a large, typically pink flower resembling an orchid. This flower has a slit designed to lure bees for pollination; however, the bees receive no reward from the plant, leading them to avoid it over time and resulting in low rates of pollination.
