'Karl Rosenfield' (Rosenfield, U.S.A., 1908) Bloemen donker karmijnrood met iets blauwpaarse gloed, gevuld, middelvroeg; bladeren donkergroen, bovenzijde stelen licht bruinrood; hoogte 80 cm; bloemstengels stevig; vertakking goed tot zeer goed. Deze zeer veel gekweekte pioen behoorde in 1996 tot een van de meest aangevoerde snijpioenen op de bloemenveiäng in Aalsmeer. De houdbaarheid op water is lang, namelijk 10 17 dagen. Weliswaar verbloeien de bloemen enigszins blauw. Door de vrij stevige habitus is de plant ook geschikt voor de tuin. Wel moet worden vermeld, dat deze cultivar licht Botrytis gevoelig is, echter de goede eigenschappen overheersen, zodat een positieve beoordeling gerechtvaardigd is.

Don Hollingsworth on Yahoo!groups [peony] 05 June 2004:
Traditionally in peony talk, it seems, a red flowered peony is one of which the pigment is too dense to be called pink. This usage appears to have grown up around the Lactiflora sorts in which the red-purple peonidin is the source of "red" and in which the opacity pigments common the good whites and pinks can render the red-purple of the petals a very un-inspiring dull magenta. (See Fred Cooper's article in the APS book, The Best of Seventy-Five Years.) One of the anecdotes frequently quoted around here is of the inquirer who said, "I have bought red peonies three times and do not have a red one yet!"
It appears that when some of the thoughtful breeders of the late nineteenth century sought to eliminate the dulling pigments, much better "red" red peonies began showing up. Peony Karl Rosenfield is a product of these efforts. Nevertheless, it's red is not a spectrum red as known in elementary school art teaching. Anyway the true Karl Rosenfield is a great peony in my view. Trouble is, how to be sure one has it. Like has been said of Daffodil King Alfred, a great many different kinds can be seen with the same tag. I very much agree with Alana's advice to look around at the plants growing in other's gardens for a visual image of the plant you hope to obtain.
Decades ago, we had what I am sure is the real Karl, from a friend who had it for additional decades before. It proved to be useful in breeding for hybrid reds, many of which do give more nearly spectrum reds, some ranging to the scarlet side (presumably due to the addition of yellow pigments via the genetic complex). Then, I fell for the advice by a mentor that a breeder pursuing the more difficult hybrid crosses should divest his collection of pollen bearing Lactis--a strategy for reducing contamination of the chosen crosses. By the time I complied with that advice, the hybrid seedlings commenced flowering and parents of some of the best hybrids were gone. Many years later when I added back Karl, the plant seems certainly to be a fake. Then I obtained stock of plants supposed to be a pink double, only they turned out to include two different red flowered doubles, one of which is a much finer plant and flower. It is easy to imagine the better one is the real Karl Rosenfield, but how is one to know?
Red Charm is everything it is touted to be, and the color great. However, there are truer reds in peonies, to my eye. While the flower color is beautifully intense and favorably free of the dulling opacity pigments, it is a bit around the color wheel toward the blue side. Of course, different eyes see colors differently. Don
