Bessie noticed that the color is really similar to Sweet Nathalie
That is very good information. My first KA's Cinder Rose bloom is opening and, though I think the color will sell well, the plant is short and the bloom is extremely shallow and has hard green centers. If it was a seedling (or if I only paid $10 for it) I would cull it. Maybe it will improve.
Edit: Correction - The dahlia I was referring to was KA's Mocha Jo and not KA's Cinder Rose. My Cinder Rose is just about ready to open.
