Rosa dumalis is a species of rose native to Europe and southwest Asia. The stems of glaucous dog rose are stout and arching, and covered with rigid, hooked prickles. This species is very much alike dog rose (R. canina), a rare southern species occurring only in the Ã…land Islands. Dog rose is sometimes grown as an ornamental. Both glaucous dog rose and dog rose are very variable species and, hence difficult to identify. The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers.
