Photo of C. candidumCypripedium candidum. The small white lady's-slipper is native to the plains of the midwestern U.S. This species needs a calcareous soil and a bit more sun than most Cyps. The plants should not be allowed to dry out during the summer. Zones 3-6.


Photo of C. californicumCypripedium californicum.  The California lady's-slipper is native to northern California and a small area in southwestern Oregon.  The plant grows into large clumps with several  flowers per stem, and the flowers are quite fragrant.  We have recently had excellent success growing seedlings in a purely inorganic mix of 1 part TurfaceŽ MVP to 2 parts perlite.  When fertilized lightly with each watering, this species grows quite rapidly.   This plant likes fairly bright conditions: 20-40% shade cloth.  Zones 7-9, possibly also Zones 6 and even 5 with winter mulching.



Photo of C. guttatumCypripedium guttatum.  Also known as the "spotted lady's-slipper," this wonderful little plant grows up to a foot tall and sports flowers with purplish-red blotches.  In suitable conditions the creeping nature of the rhizome results in a spreading of the plant almost like a ground cover.  C. guttatum is native to Alaska and is widespread in Russia and other colder parts of Asia.  Cold soil is a fundamental requirement for growing this plant.  We recommend locating it on the north side of a building where there is no direct sun during the hot part of the day.  Our plants thrive in beds with a mix of 1 part leaf mold to 2 parts sand.  Zones 2-4, and the cooler parts of Zone 5 if grown in the shade. 




Photo of C. makasinCypripedium parviflorum var.  makasin.   The northern small-flowered yellow lady's-slipper.  This is a relatively easy to grow and very rewarding plant for a moist woodland garden.  The plant prefers high open shade but a little direct sun in early morning is welcomed.  Both the small- and large-flowered yellow lady's-slipper grow into large clumps when cultivated under favorable conditions.  Zones 2-6.



Photo of C. pubescensCypripedium parviflorum var. pubescens. (Formerly Cyp. calceolus var. pubescens.)  This is the large-flowered yellow lady's-slipper. This plant is one of the easiest of all the lady's-slippers to grow and thrives in woodland gardens with open shade but tolerates early morning sun.  This plant can withstand cold northern winters even when there is little snow on the ground.  This is the best plant for people inexperienced in Cypripedium culture.  Zones 2-6.


Photo of C. reginaeCypripedium reginae.  The queen's or showy lady's-slipper. Large size, spectacular beauty, and relative ease of culture combine to make this species one of the most desirable for moist woodland gardens.  The roots of this plant should never be allowed to dry out, but the soil should not remain wet either.  This species must have a little direct sun in order to flower but enough shade during the hot part of the day that the soil does not get too warm.  Zones 2-5 and cooler parts of Zone 6.

Photo of C. reginae f. albolabiumCypripedium reginae forma albolabium.  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.


Photo of C. yatabeanumCypripedium yatabeanum. Another plant from Alaska and colder parts of Asia that resembles Cyp. guttatum but is much less colorful.  The plant in the photo is from Japan.  Like Cyp. guttatum, Cyp. yatabeanum requires cool growing conditions during the summer.  The north side of a building offers a good location.  Cyp. yatabeanum may be somewhat more tolerant of brief periods of high summer temperatures as  it is grown very successfully in Germany.  Zones 2-5.  Possibly cooler parts of Zone 6.
