Carol, the red plant is Pseudorhipsalis ramulosa and it received a lot of sun this Summer on the deck. I like the red color! Rhipsalis are another interesting plant group.
Bree, the greenhouse is heated (during the cold season) and very bright and it is not a hardship for the Orchids to be inside. And the sun-room is actually flooded with light during the day and in addition I placed some grow-lights over the bars.
This year I made myself the promise not to add any new Orchids, unless I "make room" for them. There is a physical limit to what I am able to move around, and I would think this year I did approach that limit.
