Go for trumpet creeper instead of roses
Body
Dear Neil: Two or three years ago we planted three small Amethyst Falls wisterias at the base of our pergola thinking they would bring cooling shade in the summer. They survived the cold of February 2021 and kept on growing, but when they reached the top of the pergola the plants began dying. What would have caused it, and what can we do to save the plants? If we must replant, should we use Lady Banksiae roses?
