Climbing roses are popular both with people whose enthusiasm is for old roses and with lovers of the new. Most derive from a group of wild species called the Synstylae, which have lots of small white flowers in large clusters.
Most of the hybrid groups are small, including the Ayrshire roses from Rosa arvensis, Banksian roses from Rosa banksiae, Hybrid Sempervirens or Evergreen roses from Rosa sempervirens and Hybrid Setigera or Prairie roses from Rosa setigera. It was discovered early on that China roses and Tea roses sometimes produce climbing sports of great vigor.
A bush-rose throws out a shoot that is much taller than the rest of the bush and produces no flowers until the following year. These sports are sometimes noticed, propagated, and introduced as a "climbing" form of the original bush-rose. The first were climbing Chinas and climbing Teas: examples are 'Climbing Pompon de Paris' and 'Climbing Devoniensis'.
Many had Rosa wichurana or Rosa sempervirens in their background. Roses like Sommerwind and Bonica 82 have been immensely successful as landscape roses, but they also make good individual plants for gardens.
The climbing Hybrid Teas, in particular, were issued in great numbers from 1930 onwards, and tended to replace the old ramblers in popularity. They were exactly the same as the bush roses from which they sported in all respects except their height: the flowers too were always slightly larger, though less freely repeated. Some were reputed to flower only once, though abundantly. Rose breeders sought to create large-flowered climbers that repeated reliably throughout the season.
The definition of a shrub rose incorporates no indication of size, flowering habit, hardiness, or other essential characteristic. It follows that, before acquiring a shrub rose, you need to know what you arc letting yourself in for. They include, however, some of the most rewarding of all roses. Some are separated out and given distinct names, like the early Scotch Roses, bred from Rosa spinosissima.
The best were bred by Wilhelm Kordes in the 1930s and 1940s - (Frilhlingsmorgen) and `Karl Forster' in particular. By far the most famous shrub roses now are the English Roses bred by David Austin over the past 25 years. These are intended to combine the best of the old roses (Damask scent, complex blooms) with the best of the new (health, vigour, thick petals, repeat-flowering).
Most bore large clusters of small ocher type of rose. Many of the best Wichurana ramblers were raised by Barbier in France, but many more - and Multi flora ramblers too - by rose breeders in Germany, England, and the US. Good examples of the Wichurana ramblers are Albe'ric Barbier' and `Dr. W Van Fleet'; leading Multi flora ramblers include `TausendschOn' and Goldfinch, while the 'Turner's Crimson Rambler' types are represented by 'Dorothy Perkins' and 'Excelsd. Some of the seedlings of Multi flora and Wichurana ramblers turned out not to be climbers but dwarf shrubs, with large clusters of small flowers borne perpetually throughout the growing season. These were known as Polyanthas - hardy, floriferous, and sometimes showy. A good example is `Katherina Zeimet'.
