Answer: Sounds as though your verbena is spectacular! As difficult as it might be for you, pinching the stem tips back throughout the growing season and a hard pruning in the fall will actually keep your verbena happy and healthy. It flowers on new growth so the more new growth you can encourage, the more blooms you'll see. Cut the plant back by at least one-third this winter. This will remove enough of the growth to make your plant want to grow well next spring. If there is winter damage, you can cut it off next spring.
Best wishes with your verbena!
