Hal, Strawberry Fields Forever is one of the best red and white flowers I have had the pleasure to grow. But, the bush is not what I want so I've stopped propagating it. The bush is open and likes to send out horizontal branches. However, if you don't care about that then SFF is a great cv with gorgeous flowers. If it shows up on any wish lists I will propagate it again.
I see that I posted a photo of a larger old plant of SFF in the topic Best Red and White. Note that all the flowers that show are on the same plant which shows how it tends to spread. Here's the link to that discussion
