Hello,

I have a few weeds growing by a rose plant, and the weeds are very strange looking with dark markings in the center of their leaves. I couldn't find anything on the net that matches them. The weeds are in a pond container that doesn't have drainage holes in the bottom so I am sure there has been standing water in there for a while. I need to clean it out and make holes but I would like to know what I am getting into first.

Thanks!
