Cultivated Cypripediums (Lady’s Slipper orchids) are easy to grow in the garden under the right conditions. They prefer cool, shady sites (such as the north side of a building) that don’t dry out.
They look great in combination with slow-growing ferns, epimediums, and small hostas.
It is never ok to dig up orchids from the wild. The symbiotic microbes that wild orchids depend on do not tolerate disturbance so they won’t survive in your garden. Enjoy them when you see them in their natural habitat and buy cultivars from a reputable nursery.
