We just purchased a 1908 Foursquare in Louisiana. The yard used to be a postcard but has been neglected for almost 2 years. Its dismal! We are going to bring it back but want to give the neighbors a little "happy" by planting the stone containers on 4 brick columns first. I need some ideas (Zone 8) that won't need much care since we have lots to do elsewhere and I wont' be able to reach them easily.
