Rose \Rose\, n. [AS. rose, L. rosa, probably akin to Gr. ?,

1. A flower and shrub of any species of the genus {Rosa}, of

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

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.
