Very nice! Ive got one of these as well and I cant wait to see it bloom!
Actually, shouldnt it just be C. Luminosa now? I thought all the Laelias that had been tossed into Sophronitis has been moved to Cattleya? I can never keep up.
They were first moved to Sophronitis and now have been moved to Cattleya, so Either Lc, Sc, or C is correct, but not Slc. I'm sticking with the old names, so for me it would be Lc. Luminosa.
