The tall stuff in the bog is mainly cattails, but there are those skinny ones, too. Nothing like your tall yellow sedge or whatever you call it, Colleen. All the dead stuff is the penny wart. I'd like to try to thin that stuff out, but seems either you have it, or you don't. LOL I've kept it out of the koi bog, but it has taken over the goldfish bog. May try to pull out as much as possible when things thaw out, and see how much I can keep it under control. It's great for soaking up the nutrients, I'm sure, just would like to see other things grow in there, too.
