A novel class of roses came into existence following continuous blending between the Bourbons and, it may appear, any other parent that may have come along. After some confusion initially, this class of rose was known as hybrid perpetuals. Sometime around 1820s, this race of rose was accepted as a new group and later several cultivars filled the catalogues.
However, the sheer number of these roses as well as their exceptional hybridity eventually proved to be the reason for the demise of many, while only the best among them managed to survive. It is interesting to note that all hybrid perpetual roses inherit the essential flaws of the hybrid tea roses.
Most breeders wanting to develop large, enchanting flowers that repeat bloom more often than not paid little or no attention to the excellence of their roses as garden shrubs. Yet, among the roughly 3,000 different types of hybrid perpetual roses were introduced to the market during the last century.
Some of them are really beautiful when they are in bloom and they also make hardy, healthy and well-formed garden shrubs. Generally, hybrid perpetual roses bloom profusely in spring and once again in the fall. During the intervening months the plants flower sporadically in a trickle.
The flowers of hybrid perpetual roses are large and, on an average, each flower measures anything between 3 inches and 5 inches (7.8 cm and 12.7 cm) across. However, a number of cultivators of this class of race produce giant flowers, each measuring about 6 inches to 7 inches (15.2 cm to 17.8 cm) in diameter. In addition, hybrid perpetual roses are full as well as fragrant.
Their colors range from white to pink, rose, scarlet and carmine. You will not find these roses in true orange or yellow colors. However, these roses are very cold hardy and they flourish in the south. The plants are susceptible to fungal diseases, especially when grown in places were summer months are extremely hot.
