Hello all. Our house has a large (5' x 8 ') flower box in the backyard that is raised about to waist level. It gets lots of sun. When we first moved in it had lilies and white rocks covering the dirt. Well, I finally rid of the white rocks because it was very hard to pull weeds from between the rocks. I want to re-do the box with some fresh soil and mulch. However, I also want to replace the flora in there as well. Most of the lilies have died--it's been 5 years, so I don't know if that's normal. I'm taking the remaining lilies to my parents' house, but I'd like new plants for the box. My goal is to have something that I can see year-round, even if it's not blooming, as the lilies only came out for a short period each year. My Mom has already ruled out my first idea of azaleas--she said that they get too big and people don't prune them (I just assumed I could prune them, but I don't know much about gardening). Any thoughts on something simple that I can keep in there?
