Rose \Rose\, n. [AS. rose, L. rosa, probably akin to Gr. ?,
   Armor. vard, OPer. vareda; and perhaps to E. wort: cf. F.
   rose, from the Latin. Cf. Copperas, Rhododendron.]

      [1913 Webster]

   Note: Roses are shrubs with pinnate leaves and usually
         prickly stems. The flowers are large, and in the wild
         state have five petals of a color varying from deep
         pink to white, or sometimes yellow. By cultivation and
         hybridizing the number of petals is greatly increased
         and the natural perfume enhanced. In this way many
         distinct classes of roses have been formed, as the
         Banksia, Baurbon, Boursalt, China, Noisette, hybrid
         perpetual, etc., with multitudes of varieties in nearly
         every class.
