About 2 years ago I put Firecracker Fern and Ghost Plant together in the flue tile. I can't remember if there was anything in there last year.
Recently I noticed that Coreopsis had self-seeded in there and I left it. Then I read about mulching around a flue tile and wreathing it with grapevine, which I just happened to have.
Those are not weeds; Catchfly seedlings/Silene armeria
I'm not sure that 'decorating a flue tile makes it a better container. The shrubs around the pipe will out distance it soon and have bright tropical blooms. I liked it well enough when it was plain.
What do you think? Is a wreath of grapevine an improvement or just busy work?
