What is the difference between a climber and a rambler?
Climbers generally have large blooms on not too vigorous, rather stiff growth and most repeat flower. Ramblers are in general, much more vigorous. They will produce great quantities of small flowers, although most do not repeat flower. There are exceptions to both these rules: for instance Malvern Hills and Snow Goose are repeat flowering ramblers whereas Cecile Brunner clg is a once flowering climber with small flowers. Most climbers are best for walls, trellises, arches, obelisks whereas ramblers are generally better for growing into trees and covering pergolas or large structures such as garages or sheds.
