[quote="Steve812"]Hi Cinta,
I hear you loud and clear. And it's not you. I had similar experiences when I lived in New Jersey. I also have found that freeze/thaw cycling can be much more damaging to certain roses than constant cold. For example, here in AZ we can have 80F days in February and freezing weather at end of April. The temperature can cross freezing dozens of times in between. Most Hybrid Tea roses just die. Playboy, a floribunda that did well for me in NJ, zone 6b, I cannot keep alive here in zone 7b.
I've had way more luck with old garden roses. I think Rosa Mundi was among my first successes in NJ. The same cultivar loves it here, too.
Floribunda roses have some multiflora heritage and they tend to tolerate freezing and thawing. I've been very happy here with Cherry Parfait, Day Breaker, and Rainbow Sorbet.
There are just a tiny number of HT roses that I have found fairly dependable: Moonstone, Gemini, Big Purple, and Selfridges. I'm told by several people in the NE that Savannah is a good choice.
Happy to see your post Steve. Looking forward to seeing your photos of Rosa Mundi. Cherry Parfait, Rainbow Sorbet and Savannah all do well here. I planted Gemini today - so we will see...
