This yellow woody (also called tree) peony blooms later than our red varieties. The first set of three were photographed May 26, 2021 have unopened buds. Yet, these are early compared to those photographed June 6, 2019 used in the last still life.
These first photographs were taken with a Canon EOS 5D Mark IV dslr, new for me as of 2020, fitted with a 600EX-RT Speedlite (flash) and the Canon EF 70-300 mm (variable) f/4-5.6L USM lens stabilized with the Manfrotto BeFree Carbon Fiber tripod with ball head.
Our Itoh yellow tree peony has flowers on stalks too slender to hold the heavy blooms upright. The flowers open hidden among thick leaves. Here they are a still life of cut blossoms and leaves. The cultivars of Paeonia, the mouton, or hua wang, king of flowers, are ofe of the classic ornamental genera of China. By the 11th and 12th centuries the center off cultivation was in Sichuan, and there yellow-flowered varieties appeared.

Crossbreeding of yellow-flowered P. delavayi with traditional double-flowered P. suffruticosa cultivars by Victor Lemoine in Nancy, France has led to the introduction of the color yellow into the cultivated double-flowered tree-peonies. These hybrids are known as the Paeonia × lemoinei group. In 1948 horticultulturist Toichi Itoh from Tokyo used pollen from ‘Alice Harding’ to fertilize the herbaceous P. lactiflora ‘Katoden’, which resulted in a new category of peonies, the Itoh or intersectional cultivars. These are herbaceous, have leaves like tree peonies, with many large flowers from late spring to early autumn, and good peony wilt resistance. I am guessing our Yellow Wooden Peony is a type of this hybrid because the long stems are more herbaceous than woody, the heavy flowers droop so the best form to capture them is the still life.

Compare the above two exposures to appreciate the effect of the f-stop and excellent bokeh of the Canon “L” lens.
This still life from the 2019 bloom was taken with a Canon EOS-1Ds Mark III dslr and the Canon EF 50 mm f/1.2L USM lens used above. Stabilization provided by a Manfrotto 3036 (studio) tripod with the 468MG hydrostatic ball head. That room is bright from large, east-facing windows. Late afternoon light is soaked up by the black velvet backdrop leaving the lemon yellow leaves to shine.
