Answer: Your Patio Bouquet Hydrangea is Hydrangea macrophylla Kardinal. The flowers are spectacular! The biggest challenge you'll face will be trying to keep the plant from freezing down to ground level each winter because macrophylla hydrangeas produce flowering shoots on the previous year's wood. I think it's worth a try, though. Some gardeners report success with the following method of protection: Create a large cylinder out of chicken wire and set it over the plant, then fill the cylinder with leaves or compost to act as an insulating blanket. Hope this works for you!
