As for Double Delight in the Northeast, Carol, I think it would be worth the risk. I grew it in NJ and my recollection is that I was pleased with it early on. But I also recall that it disappeared later. I'd say that Cherry Parfait might get you a plant of much easier care and potentially great visual impact with the same coloration, but there is something about the perfectly grown blossom of a Double Delight that nothing approaches.
