No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
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×(P. lutea×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.
