| There are also repeat-blooming cultivars of moss roses like R. × damascena ‘Quatre Saisons Blanc Mousseux’, which pedicel and calyx are covered with a green to brown mossy growth. The glandular ("moss") trichomes on leaves and sepals produce α-pinene and myrcene as most abundant compounds, leading to a balsamic scent. \\ | There are also repeat-blooming cultivars of moss roses like R. × damascena ‘Quatre Saisons Blanc Mousseux’, which pedicel and calyx are covered with a green to brown mossy growth.

| | Hydrosol from fresh R.damascena flowers ('rose water') contained 0.025-0.074% v/w of dissolved oil (extraction with dichloromethane), with 2-phenylethanol (67.4-72.4%) as major component along with other characteristic rose compounds like the rose oxides (tr-0.2%), citronellol (5.9-15.6%), damascenones (tr), nerol (1.2-9.2%), geraniol (2.1-16.8%), nonadecane (0.3-0.9%), nonadecene (0.1-0.7%), eicosane (tr-0.1%), heneicosane (tr-0.4%), eugenol (tr-0.4%), and methyl eugenol (0.2-0.4%). \\ |

| "Starting with cellular compartmentalization, we review the recent findings related to the formation of key aroma compounds in rose flowers. Metabolic pathways involved in the volatile formation such as the methylerythritol phosphate pathway, the shikimate pathway; and the formation of fatty acid and carotenoid derived volatiles are discussed. In addition, we summarize the knowledge about the enzymes involved in the formation of the different classes of volatile compounds." \\ | "Starting with cellular compartmentalization, we review the recent findings related to the formation of key aroma compounds in rose flowers.

| "Rose oil of commerce is obtained by water distillation of fresh rose flowers of Rosa damascena which is a cultivated species. 3.5-4 t of flowers are needed to get 1 kg of this highly priced oil. Top ranking cultivators of oil rose and producers of rose oil are Turkey and Bulgaria producing evenly the annual world demand of 3 t of oil." \\ | |
