Most are, Nancy! There are only a few that are described as being "frost sensitive" by the growers, Coral Scout is another. I tend to cover any here that come up super early that aren't known as early bloomers and any that have buds when it snows and gets super cold--have had too many disappointing bloom seasons when I did nothing and let nature have her way with my plants....
If Singing in the Rain didn't bloom until last spring you have some really fun bloom years coming up! Once it's mature enough to have side blooms you'll have flowers of different colors at the same time. The main buds open first, of course, and fade to that pretty yellow, while the side buds open to that orangey pink--my favorite thing about SitR! I don't think the individual flowers are the prettiest Itohs but the way the mature plant looks in full bloom puts it right up there for me. This pic shows it a bit--the dark pink is a different flower, of course!
