I love the dark red one too. I thought it was Sarrturm (probably wrong spelling, not my best talent ) but it's one of his crosses with Blood Tiger.
The Roter Kalif was a case of wrong pot. He was going to give me Tropical Garden ( maybe this year )
Iowa Rose was the first that came to my mind. I included a photo from my garden in today's article. I'm not sure Iowa Rose has that much cream in the center? Mine is long done blooming so I can't get a look. Next year .
Is it blooming now? Or maybe you have other photos? I'm just wondering if the cream spreads with age of the bloom. If not then not likely Iowa Rose in Celeste's photo.
