Epipactis

[frits.kp]

This is my Epipactis thunbergii yellow form which flowered in the autumn, we have recently taken -5c
of frost and im worried about this species surviving. Does any one out there grow this species, I have several orchids outside but this is in a pot / cold greenhouse.

Dave's list it to 10 C at USDA zone 8

Another site shows that it goes to USDA zone 4a

I think it should be ok outside as long as it does not get waterlogged
