Repeat Flowering
With very few exceptions the summer flowering Old Roses, wild roses and the ramblers flower only once during the spring or summer usually for about 4 - 5 weeks. Nearly all the varieties in the other groups will repeat flower. It is worth noting, however, that many of the species, rugosa and some of the ramblers set a good crop of hips in the autumn.
Height and Habit of Growth
The Hybrid Teas and Floribundas have generally rather neat, upright growth in the 2 ft. to 4 ft. (60cm-120cm) range that is best suited to the more formal areas of the garden. The great majority of English Roses, Old Roses, Shrub Roses and Wild Roses are more informal and often grow taller, between 3 ft. and 6 ft. (90cm-180cm). The approximate size of each variety can be seen by looking at the measurements which show height x width, however judicious pruning can alter the size substantially.
The climbers tend to have larger flowers and stiffer, shorter growth than the ramblers and generally repeat flower. As a rule the ramblers will grow more successfully in difficult situations.
Rose Border -
This can be anything from a low, formal border that would be best planted with bush roses to a more informal affair using English Roses, Old Roses and shrub roses. The English Roses, with their superb flowers, wonderful fragrances, repeat flowering, attractive shrubby growth and general reliability are first class for the informal border. However the addition of a few varieties from the Old Roses (especially the summer flowering group) and the shrub roses can add some extra character and variety.
