Yellow cypripedium is a rhizomatous terrestrial orchid from the mountains of southwest and central China and Tibet, prized for its large yellow slipper-shaped flowers. It is a wild species that is hard to keep in cultivation, mainly because it needs cool conditions, consistent moisture and a mycorrhizal-rich growing medium.
