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.
