Cumbria, United Kingdom
Thank you for the answer "Bamboo", and may I also thank "Philjeffs" for the humerous answer he gave. I am going to cut the whole bush back this year to try to encourage more flowers. I only cut half of it back last year as I was scared of killing it. I look forward to seeing if it produces mixed flowers, or only one colour.
