The noblest of hardy orchids, found far north in America, and thriving perfectly in England and Ireland in deep rich or vegetable soil. Wherever the soil is not naturally peat or rich vegetable matter this fine plant will succeed on the margins of beds of rhododendrons, etc. It should be sheltered by surrounding bushes, and be in a moist position. Others of the genus, and various other hardy orchids, are worthy of naturalisation ; but the mocassin flower is the best as well as the most easily tried at present.
