Rose a plant that is a member of the genus Rosa. There are over three hundred species and tens of thousands of cultivars. Many roses are cultivated for their beautiful flowers, which range in colour from white through various tones of yellow and pink to dark crimson and maroon. Their flowers vary in size and shape and are usually large and showy.
