Hydrangea paniculata Limelight, large white blooms tinged with pale green; trailing Ivy at the base spills over the sides of the classy zinc planter boxes. Baltic Ivy (variegated creamy edge) would combine well too.
Love these plants for the front planter box - create a sense of privacy at the front door. Shade loving container gardening, planters for front porch, ferns, hydrangea and sweet potato vine. Gorgeous and welcoming.
