I don't grow Chatworth ...but ohhh my, what a nice combination with the orange of Westerland rose!!!!

I had one a few years ago. I thought the flowers were a bit too gray for my taste, but when I finally started to appreciate it more the second year, it up and died on me. I was hoping for the next 2 years that I would see new shoots coming up (I didn't dig right away to see if the roots had rotted) but they didn't emerge.

But I didn't like it enough to look around for a replacement.

I much preferred Hanna, who is planted in the same general area, also light blue and bell shaped.
