I picked up a Psychposis Mendenhall at the Sacramento Orchid Show on April 19, 2015. I don’t remember the vendor. I paid a good price for this one. It came with four spikes, and looked pretty good. I broke off one spike getting it to Davis, and repotted it into S/H right after I got home.
One of the spikes bloomed with a very nice bloom, but the other two have not. The plant struggled with the move to S/H, and I think that the bloomed spike and one of the others has died. However, the plant is drinking a lot of water, increasingly over the past month.
