Double type; large; midseason. Very bright crimson with very little blue in it, outer petals large and waved, central petals incurved and notched; not fragrant. Tall; free-flowering; strong stems. Good foliage. Of good clear color, excellent form, and reliable blooming habit. Considered by many to be the best red variety. Good for both cutting and garden decoration.

From the Dutch peony testing series in 1998(1), own translation:
‘Karl Rosenfield’ (Rosenfield, USA, 1908) Flowers dark carmine red with a blue purplish hue, double, mid early; leaves dark green, upperside of stems slightly brownred; height 80 cm; stems sturdy; number of stems good to very good. This much grown peony belonged to one of the most sold peonies at the Aalsmeer flower auction in 1996. Vase life is long, some 10-17 days. The flowers fade somewhat towards blue. The sturdy habitus makes this plant fit for the garden. It should be noted however, that this cultivar shows some susceptibility towards botrytis, but the good characteristics predominate so that we can review it positively.
