One big problem for you, and me, is that our winters are harsh enough to kill back the top growth in many years, taking the flowering buds at the tips. This past year has been a most unusual one and we've had great flowering around here. But that's the exception.

My friend has a Snowflake and it's planted in dappled shade, and never really gets much direct sun and it is covered with blooms this year. There are other varieties of Oakleaf growing in full sun and they're doing great, too.

The bottom line seems to be that it's not too critical here in the North where you plant them.

Thanks hayseedman. I am guessing that this should be winter protected? All of my others are new growth bloomers (ES, F&E,QF, LL) as I did not have much luck with any that bloom on old wood.

I don't know how you'd winter protect a large one. Maybe you could protect one that's young for a while. The larger ones are pretty stiff and it'd be difficult, I'd imagine, trying to cover it or something.

I actually haven't had such good results with Endless Summer without somehow protecting it. It's a little better than Nikko, say, but still not a very reliable bloomer.

Blue Billow blooms consistently for me. Preziosa works sometimes.

The Paniculatas all do just fine.
