Oranges and Lemons

I’m always intrigued by Oranges and Lemons (Roller Coaster x New Year) when seeing it in bloom at the nursery since it contains two desirable colors, a pure orange and decent yellow. On searching the forum there are only a couple of references to it - anyone have any experience growing and using it?

My neighbors (Z5) have two plants; healthy, but plants die to ground most winters, and never accumulate much size.
