Tiffany, you have a nice collection! I especially like the P.rotundifolia
Here's my variegated Peperomia Scandens. It grows anywhere, sun, shade, inside, outside, not picky at all. Love this one. I started out with a few pieces in other pots, just to add some interest, and they've grown so much I've had to give them their own pots. They look particularly nice cascading out of a hanging basket.
