Woody (Tree) Peonies
Very early in his peony breeding endeavors, Professor Saunders began crosses with woody peonies. These peonies were (and still are by many) referred to as tree peonies but because they are multistemmed and short, “woody” or “shrubby” are more accurate terms (as Saunders himself wrote). The American Peony Society encourages the use of the term “woody”. The woody peonies cultivated for centuries in Japan tend to be single with colors ranging from white through pink; these are the ones Saunders used in his crosses. (Earlier breeders in France used double forms from China.)
Current taxonomists use the term Moutan to refer to the entire section of woody peonies with the suffruticosas in the subsection Vaginatae. Recent DNA research shows that the suffruticosas are hybrids of several species so the correct designation is Paeonia x suffruticosa.
China is also the home of the subsection Delavayanae, including P. delavayi with red and orange flowers, and P. lutea (or P. delavayi ssp. lutea), P. ludlowii, and P. potaninii with yellow flowers. Saunders apparently had forms of at least three of these species – delavayi, lutea, and potaninii (photographed by Silvia Saunders in 1934 under the name forestii trolliodes) but likely did not use the latter in his breeding program. The first P. lutea Saunders obtained was likely a cross with the reddish P. delavayi and is referred to in his notes as “L-D”.
Saunders crossed various Moutans with P. delavayi or P. lutea to produce a wider range of colors and patterns. He called these lutea hybrids, a term still applied today. Most notable were the golden yellow hybrids, ‘Argosy’ being the first. Because of the considerable time between making a cross and obtaining a mature blooming specimen and the relative infertility of the F1 hybrids, Saunders only produced a few F2’s. ‘Heart of Darkness’ is one F2 he named. His breeding work was first carried on by Nassos Daphnis in the gardens of William Gratwick and then by others, notably David Reath and William Seidl. When Silvia Saunders closed the nursery she distributed his plants to Reath.
His woody peony breeding notebook only occasionally records specific species and cultivars as the parents of his cultivars. References to “Reath and Saunders” refer to an article in the American Peony Society Bulletin written by David Reath and Silvia Saunders and reprinted in The Best of 75 Years, APS, 1979. Seedling numbers were obtained from Silvia Saunders’ Notebook and from index cards given to APS.
