Around the end of the eighteenth century France witnessed the emergence of a rose of great significance. Like in many other instances, the origin of this rose was unknown, but it became an instant favourite of rose gardeners owing to its habit of flowering almost consistently all through its growing season. When the rose arrived in France from England it was named R. portlandica. However, later it was christened to 'Duchess of Portland' - named after the third Duchess of Portland, who is famous for brining the rose from Italy to England. It is believed that this rose had its origin in a cross between a Damask x Gallica seedling with an unidentified China rose, most likely 'Slater's Crimson'. This mating was believed to have established, at least partially, the very useful remontancy (the ability of a plant to flower more than once in a growing season or year) habit of several roses that we see in the present times. In fact, Portland roses are yet another class of the Old Garden Roses that repeats their blooms during its growing season. Together with the Teas, Bourbons, Chinas, Hybrid Perpetuals, Noisettes and other roses, they are responsible for dismissing the popular conception that Old Garden Roses bloom only once in a year. It appears that, Portland roses have their origin in natural crosses between Chinas and Damasks. In fact, both Autumn Damask and Slater's Crimson China are presumed to be the parents of the maiden Portland that was discovered near Paestum in Italy. The original Portland rose, 'Duchess of Portland', is also referred to as Portland Rose. The origin of this red rose dates back to 1800. After this rose was introduced in England and France, numerous hybridizers swooped on it and they created many more hybrids. During the middle of the 19th century and before the Hybrid Perpetuals were introduced into the market, Portland roses were very popular and they continue to remain a favourite of Old Garden Rose enthusiasts. Portland roses have played a vital role in developing the modern day roses because these roses, together with the Hybrid Chinas and Bourbons, parented the Hybrid Perpetuals - which are the parents of the modern day Hybrid Teas. There is no doubt that Rose du Roi, an exceptional red Portland rose, is considered to be the progenitor not only of the maiden Hybrid Perpetual, but many others too. There was a time when about 150 varieties of Portland roses were in cultivation. In present times, only 16 Portland roses are listed in Modern Roses. Nevertheless, there are roughly about another half dozen varieties that may perhaps be classified as Portlands. Interestingly, Portland roses do not have any climbing variety. This class of roses generally have vigorous growths but they do not become overly large plants. On the whole, Portland roses have a nice garden size and can be accommodated in any average garden. Portland rose possesses a number of distinguishing characteristics and one of them is that the blooms of this rose appear "on the shoulder". In other words, the stems between a Portland rose and the first foliage is extremely short. It appears as if the flowers are resting on the foliage. The blooms of this rose appear in a variety of colors. The color range of Portland rose varies from white to pink to red to purple. However, roses in this class do not bear yellow or orange flowers. The class of Portland roses do not comprise very many cultivars - in fact, even during its hey days in the 19th century, this class of rose possibly never had more than 100 cultivars. At present, Portland rose comprises less than a dozen cultivars that are in cultivation. In fact, these roses were admired greatly during the early 19th century because they are hardy as well as rebloom many times in a year. The plants produce a heavy crop of flowers in the beginning of summer and they are again in bloom, although occasionally, all through the summer months and even into the fall. While the flowers of Portland rose are large, each measuring anything between 3 inches and 4 inches (7.6 cm and 10.2 cm) across, and also uncommonly heavily fragrant, in present times, many of the roses in this class have been replaced by free-flowing, flashy roses. Portland roses have adapted themselves well to the conditions in Midwest, Northwest, Rocky Mountain West and even in Canada where the climatic conditions are milder. However, they suffer in places where the summer months are hot and humid. Below are brief descriptions of some of the popular and better known cultivars of Portland rose:
1855 This Portland rose dates back to 1855 and its blooms are similar to Damask. The flowers of 'Arthur de Sansal' are very double and have a rich crimson-purple hue.
