Old Roses that were the first to result from systemmatic crosses between European and China roses to increase the frequency of bloom. The first was a chance seedling that occurred from a cross between Damasks and Chinas on the Island of Reunion, then known as Bourbon. Bourbons are large plants bearing flowers that are typically formal as are Gallicas and in the range of colors and sizes of Gallicas - purples, roses, pinks. They are quite fragrant and they typically blossom twice a year, spring and fall. The group includes Louise Odier, Souvenir de la Malmaison, Madame Isaac Perriere, and Zephyrine Drouhin.
