A beautiful show. I wanted to cry when I saw your Rhyn retusa. I just bought one, a beautiful plant with the start of a flowering. The first 5 or 6 buds opened and then the remainder dried up. Possibly because of the shipping, or the change from greenhouse to me. At the least, I did enjoy yours.
All very beautiful! The pale green den with the dusky pink lip and the white den with the purple lip are identical to two noids I bought at Bunnings (like your Home Depot). I can now put a name to them, great!
