Does your Silver Mound Artimesia get nice and full then seperate in the middle and flop over? Mine does. So I have an idea I am going to try. I bought, at the dollar store, a plastic baseball cap cage that is used to keep the cap's shape when it is washed. I am going to take it apart and cut off the bill part to leave me with two white plastic domes that are cage like. I will put one over each plant in the spring and let it grow up through the openings. I think this will help the Silver Mound stay a "mound". What do you think?
