Jim, beautiful blooms! The C bicolor x Schom is awesome. I love the lacquered blooms!
I found the Dutch Slippers in bloom again this Summer.
Bulbo frostii
I tried to get some pictures of the Den bigibbum v. compactum, blooming very nicely right now, but always looking a bit wild.
The first picture is from this morning, the second one was taken this afternoon. The color appears a bit too bluish in afternoon light.
And - update on the Encyclia brassavolae
