Roses whose long canes can be trained along fences or walls, variable in flower size, form and mature habit.
How to Get Your Climbing Roses to Bloom More
All rose plants manufacture a "blooming" hormone at the top of the cane that signals the plant to bloom-- at the top of the cane. If you bend the cane horizontally, that hormone travels down the cane, signalling the plant to bloom all along the length of the cane, rather than just at the top.
Climbing roses, as you know, don't attach themselves to a support as vines do, but have to be tied to their support by the gardener. If you attach the canes horizontally to a fence, or spread them slightly when you attach them to an arbor, you'll be delighted with many more flowers, blooming all along the cane.
Be sure to deadhead the spent flowers on any everblooming rose. This encourages new blooms to develop faster. Prune off the spent flower or flower cluster, and its short stem, right down to the leaf axil on the main cane. New flowers and stems will grow from that same leaf axil.
