Elaine, I am not sure how this relates to growing in Florida, but this is what happened some years ago here - I had a pot with Ludisia declining by the end of Winter. Pieces were falling off here and there, it looked terrible. Came Spring I dumped the fairly large oval planter into a corner in the garden, thinking I will reuse the still nice pot.
Summer came and went and it was time to bring things inside. I looked at the planter in utter disbelief!! It had received hours of full sunshine daily!!! The plant looked healthy and robust, only the leaves were not as dark as one would expect.
Since then, I keep this one a bit brighter than I used to and keep it potbound.
Mind you, this is NJ!!
