This cross is Barbara LeAnn x Rosalie Dixler, from the few seedlings I got from that cross it was the only one with pointed petals... And the only one I kept!
Interesting. The only time our breeding of this grex resulted in more pointed petals is when Rosalie Dixler was used as the capsule parent. I'll try to find a photo of our FVF 'Wings of Fire' clone to illustrate; Rosalie Dixler was also the capsule parent in its breeding.
