Paeonia suffruticosa Andrews - Paeoniaceae - **Strauch-Pfingstrose**, Baum-Pfingstrose

Deciduous shrub, up to 2m tall; native to China, cultivated elsewhere as an ornamental garden plant (cultivars and hybrids Paeonia × suffruticosa); flowers terminal, solitary, 10-17cm across, with pleasant fresh rose-like floral aroma, petals single or double, red, red-purple, pink or white.

"According to major fragrances and the results of sensory evaluation, thirty cultivars were classified into five fragrance patterns: a woody scent, a rose scent, a lily of the valley scent, a phenolic scent and an unidentified scent, in which cis-ocimene, d-citronellol, linalool, 1,3,5-trimethoxybenzene (TMB) and pentadecane were their major floral fragrances, respectively." \\

Main components of the essential oils from fresh flowers were (Z)-3-hexenol (1.1-17.2%), hexanol (0.8-9.4%), trans linalool oxide furanoid (0-8.9%), cis linalool oxide furanoid (0-4.8%), linalool (0-9.1%), phenylethanol (0-30.9%), 1,4-dimethoxybenzene (0-17.0%),  α-terpineol (0-2.6%), 4,7-dimethylbenzofuran (0-2.6%), nerol (0-10.6%), citronellol (0-30.7%), geraniol (0-12.5%), 1,3,5-trimethoxybenzene (0-7.4%), germacrene D (0-5.5%), and hydrocarbons like pentadecane, (E)-8-heptadecene, heptadecane, nonadecane, heneicosane, and tricosane e.g. Hydrolate extracts were especially rich in phenylethanol (up to 64%), nerol (up to 14%), geraniol (up to 19%), citronellol (up to 44%), and 1,3,5-trimethoxybenzene (up to 21%). \\
