LARGE FLOWERED CLIMBERS
The class known as Large-Flowered Climbers has become a disorganized catch-all, including seedlings of Climbing Hybrid Teas, seedlings of repeat-blooming modern shrubs which exhibit a climbing tendancy, and once-blooming ramblers which make large flowers. To confuse the situation even more, one of these once-bloomers, Dr. W. Van Fleet gave rise to a repeat-blooming sport, New Dawn, which has contributed its genes to many of the healthiest and hardiest modern climbing roses. In an effort to make some sense of this mess for the average gardener and rose-grower, we include here all those large-flowered, repeat-flowering modern climbers which are not sports of bush roses. The once-blooming LCls will be found in the section on Ramblers.
Despite the hybrid complexity of this class, it can be reduced to about three styles or habits of growth;
1. (E.g., Cupid) Those few that have the same long-caned habit of the climbing sports of Hybrid Teas, producing long canes and short lateral growths that flower.
2. (E.g., New Dawn)
Tthe hybrids derived from Rosa wichurana, which make long, rather flexible canes with a wealth of lateral blooming wood.
3. (E.g., Royal Sunset)
A large number of hybrids that are upright, spreading growers, flowering at the ends of all new growth, gradually making a complicated mass of secondary canes.
