I've seen some really neat setups with dead varnished bamboo in an old aquascaping book. I'm surprised I haven't seen any on this forum. Sorry I know that doesn't really answer your question. You just kind of reminded me of something I was going to try out. I think when I set up my shrimp jungle I'm going to give that a stab with some low light plants.

I'm in the Saint Louis, MO area and always looking to connect with other planted tank enthusiasts.
