Begonia Rex "Escargot"

Its you! I only water mine when the leaves are droopy. Don't chuck them out yet. Let them dry off. Put them somewhere you'll forget them and come back to them in a few weeks time. See if there's any sign of life then. They seem remarkably resilient to me. My original Snail is still in the pot/compost that it was given to me. It would probably benefit from splitting but, that takes effort, so i won't!
