Itasca Lady's Slipper Farm in Bovey, Minnesota sells Lady's Slippers across the United States and will ship the plants as bare roots directly to you in the spring and fall only. In summer is on site only sales. One of the featured Lady's Slippers we sell is the Cypripedium albolabium. This is a white-flowered form of the showy lady's-slipper.  These plants are identical to the normally colored form but have blooms with a pure white lip.  There is no pink whatsoever.  Forma albolabium seems just as vigorous and cold hardy as the normally colored plants.  Zones 2-5 and cooler parts of Zone 6.
