Itoh hybrid. Parentage: (Old Farmstead™ Carr East № 2) x [P. (Lutea Hybrid) 'Alice Harding'].
Presumed near infertility: "The Itoh Hybrids have for long been known to be highly infertile. Recently, chromosome count findings show they are triploids, reason enough for the observations. Any seeds from Itohs pollination by either triploids or tetraploids are expected to include a share of tetraploids, possibly fertile. Suggestion: pollinate by one or another of their parental Lutea Hybrids or a mix thereof. Expect rare success, requires patience, but persistence is how we got the present generation of Itohs."

The present invention is a new and distinct cultivar of peony plant, a hybrid between three species, two shrubby and one herbaceous species; of the genus Paeonia, interspecific hybrid (Paeonia lactiflora X (P. lutea X P. suffruticosa), combination of species now known as Itoh Hybrids. The present cultivar's uniqueness is characterized by its outstanding yellow color with a superior tree peony flower type on a singularly healthy herbaceous plant, its excellent hardiness of flower buds and consequent reliability of flowering in relatively extreme climates, and, by its distinctive foliage and plant habit.
