Last year I bought a lovely purple lobelia for my tiny pond. It settled in happily for a few weeks, then over the course of a few nights a mystery critter carefully stripped all the red skin off the plant, leaving naked white flesh (kind of like deer stripping bark off trees but on a smaller scale).
I got another one and the same thing happened. I moved it into the middle of the pond and it stopped, so whatever it was doesn't like getting wet.
Any ideas what the culprit might be? ???
