JB-- the temperature cutoff I believe is 68*F. So your house and the greenhouse which is warmer than your house are going to be in the same coloring range. You need something cooler to explore other options :)
Hmm I like your old salmon, the Twilight Tangerine, Christmas Flame, Peaches and Cream, Christmas Fantasy, and the pink easter cactus. I also like your S x buckleyi pictured here and the S. russeliana, Le Vesuv, and Samba Brazil.
I also understand that is a lot lol.
