I have one more lady’s slipper we found in May to share. Cypripedium candidum or small white lady’s slipper requires moist and full-sun exposures, such as may be found in wet prairies, meadows, fens and forest edges. The reason for its rare status (likely found on fewer than five locations in the state) is due to habitat disturbance and orchid poachers digging them up for horticultural uses.
This species can hybridize with C. parviflorum (yellow lady’s slipper) when found in close proximity. This can potentially be a conservation concern in some states, but to my knowledge, there are no close associations between these two species in Missouri.
It was wonderful finding this and the other lady’s slippers in the state this year. I’m hoping this one can still be found here far into the future.
