Paul, gorgeous shot! I was checking for this cultivar online and all I found was a Princess Caroline listed on several websites, described as a deep salmon-pink variety with traces of red.

I bought this at Lowe's a couple of summers ago. it was labeled Princess Caroline and I also got one they called Red Caroline. The shades of pink varied as did the reds. Delphs are not reliable here. This summer the red one was gone and the pink one had many small divisions but did not bloom. Will see what next summer brings.

OK, so I'll change the name to Princess Caroline, you had it entered as Pink Caroline.

Thanks....my error

Well, it is PINK! You were close.
