These are more pliable in growth than Climbers and generally flower only once. The individual blooms tend to be smaller and come in large trusses, but for sheer quantity of bloom they are unsurpassed. Although normally trained upwards to cover trellis, fencing, wails etc. their lax nature makes them useful for trailing down slopes and cascading over walls. Some of the very vigorous sorts can be trained up through trees or used to smother unsightly buildings etc. Pruning Guide: They require little pruning apart from a shortening of lateral growths and the usual removal of any dead, diseased or spent wood in autumn.
