these were given to me and I have no idea what they are and they do not look like they are doing well. do they need full or partial sun? I have some good plant lights, will that help them?
One on left is probably Columnea or Aeschynanthus - without flowers it is hard to go further. One on right looks like a Tradescantia sp., though none that I am familiar with.
#1 is a Lipstick plant .. and #2 is a wandering jew .. i cant think of wich one it is right now .. Marn
