Dendrobium cuthbertsonii
 

The website that I ordered this orchid from was supposed to send me an email when my order shipped with a tracking number. They failed to do so. The cuthbertsonii orchids set in the mailbox overnight at 37 degrees. Will that low degree have an adverse affect on them?

I think they will be OK. They are forgiving of cold, heat is much more of an issue. (Glad this didn't happen in summer!)
