Jake,
All of our breeding clones came from the late Dr. Clements. None had clonal names, just numbers. A few were marked "Peru" after the number and they tended to have a rounder flower form and were more saturated red in color than the others. We chose our breeding stock from the ones marked "Peru". Our 'Fox Valley' FCC/AOS , 'Fox Valley Flame' AM/AOS and 'Fox Fire' AM/AOS clones are all from his "Peru" group of plants. John M's Phrag. besseae 'Carlisle' clone also appears to be more red than most.
