Large red leaved plant, similar to a gunnera
It is probably a variety of giant rhubarb.
I want to start a garden, but specifically, I want to grow Riverside Giant Green Rhubarb. I have made several attempts to locate information on where to purchase crowns of this plant. But, have not been successful. Can you help me locate sellers?
We don't recommend vendors or products but your local extension might be a good place to start. Reputable mail order nurseries should have them. I would avoid any individuals selling "rare" or "exotic" plants or seeds, especially on auction type sites.
