Answer: The terrestrial orchid Lady's Slipper, Cypripedium, is nearly impossible to establish from seed so you will probably want to purchase plants -- please look for those which have been nursery propagated rather than wild collected. This plant is also extremely difficult to grow unless you can provide it exactly the right soil and environment, so you might wish to experiment with just a few at a time until you find the right spot.
Carson Whitlow, a well-known authority on these plants, sells some. http://www.orchidmall.com/cyp.haven/index.htm
