Gloria, I'm not sure I'm understand what you wrote about the Verbasiums and foxgloves. Are you laying them on the ground after they are finished blooming so their seeds drop in a specific area? Do you cut them down and then lay them down? It is not your explanation, just my reading comprehension so don't be offended. What do you mean by proliferations at the joint? Are these plants reseeding themselves and starting new plants where you have laid them down? Can you or somebody else that reads this explain what Gloria means or is accomplishing there? I wished I could see Gloria's gardens. The way she writes about her flower beds and what all she has planted makes me feel it must be beautiful to look at.
