Understanding Coryanthes

[islaverde]

Do all Coryanthes go dormant even when in their native habitat, or when conditions continue to favor growth?

I got a Coryanthes leuococorys that has lost ALL its leaves, and despite that, has now put out a spike! weird. The Cory grown next to it, Coryanthes huntleya is still happily growing with nice green leaves.

I try to grow them wet; from what I read from the internet. One of them is literally swimming in a wad of wet sphagnum moss!
