I want to plant a row of shrubs along the back of my lot. I want to maintain them at 6 to 8 feet high and bushy from top to bottom. My problem is that where I want to plant them gets fairly wet. Water is slow to soak in after a rain and takes forever to completely dry. We call it muck soil, not sandy, not clay and not a topsoil, just muck. I need plants that can tolerate this type of conditions well. Wife says we need plants that like to get their feet wet. Any ideas??
