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.
Hydrangea starts from cuttings. Put cuttings in water for an hour. Then plant in soil, water, insert sticks higher than the plant, place plastic bag over sticks to create a greenhouse. Place in indirect sunlight for 3 weeks and water occasionally.
