These are the "hundred petaled" roses or "cabbage roses" made famous by Dutch still life painters and are the result of hybridizing efforts by Dutch breeders in the seventeenth and eighteenth centuries. The Centifolias are distinctive shrubs, with large, coarse leaves, numerous prickles, and long, floppy canes. All are extremely fragrant. Centifolias are also very tough, winter-hardy plants that show few problems with fungal disease. Centifolias are one-time, mid-summer bloomers noted for the fullness and size of their flowers. They range in color from dark pink to lavender. Because their large blooms often weigh down the canes, many gardeners prefer to grow Centifolias as pillar roses or to train them over low fences to keep the flowers propped up.
