Voss - My Scentimental never was non-variegated with our oppressive heat last year.. But I know that Rock n Roll is supposed to be better. But, at the same time, from what I was told, almost all striped roses hate extreme heat. My Citrus Splash never was variegated & George Burns never showed the yellow, just red & white. Oranges & Lemons always goes more Oranges than Lemons when it gets that hot. However, my mini Pinstripe was always nicely variegated. But, at the same time, it got like 4-5 hours of shade, too.
