As much as I hope to see luscious re-blooming, I have to accept some years either heat will diminish that or Japanese beetles will devour every bud as it opens. So as long as I get to enjoy a glorious first flush, I'll be happy. Any blooming beyond that is a cherry on top!
I think lots of water is a key to promoting re-bloom and sustaining first flush, but I believe most would survive and provide a yearly display if somewhat moisture deprived. I'm thinking back to drought years and how they dealt. They just didn't grow, and were more susceptible to blackspot, but were fine the following spring.
Porkpal, how's that for some enabling, LOL. Are there any in particular you have had your eye on?
