Jackie, I bet philodendron would work great in those, and you can find smaller leafed types.
I love Sedum 'Fine gold leaf'!! I don't have this issue within the same pot, but I have 2 different 4 inch pots that look different, I just assumed one had more exposure when growing, and that the other will eventually look the same once its in the elements! I agree with Lynn, that it looks like it could be 2 different sedums in your pot!
