Yeah, that's what I thought, too much sun for the pink. Thanks for the help! It's hard to keep everybody cool and shaded here, plants, pets & people. The east end of the porch where this pot hangs is the lowest-light area I have. Sounds like it should be having more pink soon, especially when it comes inside. When this pot gets a re-do, I'll move the Columnea to the shady side, if the combo stays the same.
The Gesneriads are a whole group of awesome house plants that are rare to find. In almost 7 years, I'm still looking for Streptocarpella here. Even AV's seen out of fashion currently.
