One of my Farfugium seems to be slowly being eaten away. I know I have slugs in my garden on occasion, but have not seen evidence of other pests, but it's not clear to me if this is what slug damage looks like. I'll note there are no signs of mites/whatever on the underside or top of leaves, and that no other plant in that garden are seems to be suffering the same issues. Any thoughts?
