Ursula, regarding capturing the subtle color changes of Cym. Golden Elf, I think again it is getting them into the proper lighting to make these color changes show up and a close up works much better, and of course I can't find my close up, but this picture does slightly show some of the colored highlights in the veining.
Cymbidium Golden Elf 'Sundust' is in the late stages of blooming right now, but the blooms look like they had been attacked by Thrips, so I didn't even bother to take a picture.
