I hope you don't mind some ancient history. Over 20 yrs. ago as a student I lived in Anaheim with several other girls in an older rental home. There was a small area bordered by concrete that used to serve as a flower bed but was full of weeds when we moved in. That spring we were inspired to buy several roses at the local home center and we dug up the little bed and planted 6 roses. One was Chrysler Imperial. This rose was impressive with very little care by girls who knew nothing (and I mean nothing!) about growing roses. It was one of the stronger growers of the six. I remember that one cut flower would perfume an entire room. After I was married, I discovered that it was my father-in-law's favorite rose. He also lived in Southern CA and he always had one growing somewhere in his yard. He was hardly a gardener, let alone a rose expert. My guess is that it will do well for just about anyone in Southern California with perfunctory care.

This may be long after the fact, but I hope that you were happy with your choice. Mister Lincoln is also a lovely rose, although I never tried to grow it in Southern California and have no idea how it stacks up to Chrysler Imperial.
