The Bourbon Rose (Rosa Bourboniana) is a native of the Isle of Bourbon, and is supposed to be a hybrid between the common China and the Red Rose of Four Seasons.  It was introduced to France in 1822.  There are now a great number of varieties belonging to this class, including some of the best-known florists' flowers, such as Souvenir de la Malmaison, a rose that is nearly always in flower, and which no garden is complete without.  In the following list will be found most of the leading varieties:
Paul Joseph— Flowers large, dark purplish crimson.
