Rosa spinosissima L. syn.Rosa pimpinellifolia L. - Rosaceae - burnet rose, Scottish Rose, **Bibernell-Rose**, Dünenrose Deciduous shrub, up to 180cm high, native to Europe, western Asia and northwest Africa, introduced to northwest America; stems with very numerous stiff bristles and many straight prickles; leaves pinnate, burnet-like (hence the name!); flowers with 5 petals, creamy-white, 2-6cm in diam.; hips globular, dark purple to black. [[https://roses.shoutwiki.com/wiki/Rosa_spinosissima_L.|Rose Biblio: Rosa spinosissima]] Numerous cultivars with pink, yellow and and red petals are grown. [Kunc, Nina, et al. "Determination of Volatile Compounds in Blossoms of Rosa spinosissima, Rosa pendulina, Rosa gallica, and Their Cultivars." Agriculture 14.2 (2024): 253] "In emblematic terms it is particularly associated with Scotland, where it is traditionally referenced in poetry and song, and is a symbolic native plant second only to the thistle." [[https://en.wikipedia.org/wiki/Rosa_pimpinellifolia|wikipedia]] Main volatile components of the flowers were limonene (0.1%), phenylethanol (9.1%), geraniol (1.3%), phenylethyl acetate (1.1%), citral (2.4%), geranyl acetate (17.6%), and caryophyllene (0.8%). \\ [Verhoeven, H., Blaas, J. & Brandenburg, W.; Fragrance Profiles of Wild and Cultivated Roses. Encyclopedia of Rose Science, eds A.V. Roberts, T.Debener, S.Gudin, (2003), 240-248] Main components of the volatile phase (headspace of resh frozen flowers; μg IS 3-nonanone equivalents/g sample) in R. spinosissima and its derived cultivars were: myrcene (0-2.0), hexanal (0-53.2), (E)-2-hexenal (0-15.0), lavandulol (0-1.5), citronellol (0-1.7), phenylethanol (0.7-6.4), nonadecane (1.4-7.0), heptadecane (0.1-1.5), 1-henicosene (0.3-3.4), and acetic acid (0.1-1.4). Olfactory interesting minor components were e.g. (E,E)-2,4-hexadienal (0.2-0.6), benzaldehyde (0.2-0.7), citral (0-0.2), nerol (0-0.2), geraniol (0.1-0.6), benzyl alcohol (0-0.7), and the ' tea-like' 3,5-dimethoxytoluene (DMT; 0-0.5) known from [[rosa_indica_fragrans_hybrids|hybrid tea roses]]. \\ [Kunc, Nina, et al.
