I posted this on "Gunnera support group", but it was an old thread, so I'm posting it here, too...

I just received my first Gunnera plant!

Now, I know they are not supposed to survive the winter in my zone,however, I do the cement leaf castings, and I figure that even if I get a few "baby" leaves this season, it will be worth it! Of course, I am still going to try to keep it over the winter. I need an opinion though-I do not have any damp areas in my yard, I was thinking of taking an old plastic pond liner, burying it in the ground, and drilling holes in it about a third of the way from the bottom, so it will hold some water, filling with soil and planting in that. How do you think that will do?
