Registration description:
Official registration can be found at: The American Peony Society

Received December 08, 2021. Parentage unknown. First bloomed 2007. Following the registrant’s last visit with him that year, this plant was received from Roger Anderson in 2010 with the label “Yellow Breeder Plant.”  Has since had distribution under garden name. Blooms early-midseason, about the same time or shortly before ‘1, own translation:<br /> 'Red Charm' (Glasscock, USA, 1944) (P. lactiflora x P. officinalis) Flowers dark red, very large, double, centre filled with many deep red petaloids, surrounded by two circles of large petals; leaves rather large, dull green; upperside somewhat irregular; height 100 cm; stems rather sturdy; number of stems mediocre. This American cultivar is remarkable thanks to its magnificent colour and the enormously large flowers, which need support to remain upright, despite the plant having sturdy stems. The mediocre number of stems and the development of so called 'necks' on the roots inhibited propagation and distribution at large scale for some time. 'Red Charm' is reportedly somewhat susceptible toward botrytis, which was also noted by the review commission. It is a good garden plant, despite some negative characteristics.</p> <p> </p> </div>" href="https://www.peonysociety.eu/registered_peonies/red-charm/">Red Charm’. Generally SEMI-DOUBLE but also produces many DOUBLE flowers when mature. Light yellow, 1 bloom per stem, 6 inches in size (15 cm). Average of 3 carpels, greenish-yellow, sparsely hairy. Stigmas red, normal anatomy. Pollen-bearing stamens, filaments yellow. Staminodal disc consists of a few projections, greenish-yellow. Highly fertile both ways, presumed tetraploid, good breeding potential. Light fragrance. Strong upright growth to 33 inches (85 cm). Mechanical support not required. Glossy green foliage stays healthy until late autumn. Vigorous growth and rapid increase produces a high stem count in comparison to most other herbaceous hybrids. This, along with well-shaped round buds, offers good cut flower potential. The cultivar name is based on the Spanish word for yellow, reflecting the clear yellow color of the flower.
