Hello, buy yourself a Plum Crazy Hibiscus and plant it. We have alot of clay soil in areas here. I am in Knoxville. I usually did a hole and fill it with Miracle Grow soil and some humus and some perilite and plant away. I have many plants and flowers. That Hibiscus I planted 3 springs ago now grows 5 feet high and 5 feet wide with big plate size flowers. I will take a picture if I can remember soon as it blooms this year.
