I just cleaned out my rainwater collection tanks because they were full of slimy stuff that the plants weren't liking, and I found a piece of what looks like Spanish Moss. It was bright green and about six inches long, was unrotted despite being submerged in a gross bacterial sludge. Because I only dunked the moss once, the piece would have to have been in there since before Christmas, so about three weeks ago. Does anyone else have experience with T. usneoides growing successfully underwater, or is this just a weird one? I'll get pictures of it soon.
