Climbers and wall shrubs for sun

South- or west-facing walls and fences often receive prolonged direct sunshine. So, if you want to plant something in these spots, it is important to choose plants that can cope with direct sun, periods of dryness and the heat that is reflected from the wall.

Quick facts

Top five plants for sunny walls

Introduction

Climbers have a natural tendency to climb and some will even self-cling, without requiring tying-in to supports.
 
Wall shrubs, by contrast, do not naturally climb. If left alone, they bush outwards and grow like shrubs. With specific pruning and training techniques, they can be trained to grow against walls.

Practical considerations

Choose plants that will be happy in your garden soil conditions. Some plants are adapted to different soil types (clay or sand for example), and others require acid soil conditions.

Make sure your pruning and training technique encourages the plant to cover the wall as quickly and efficiently as possible. Climbers and wall shrubs require training and pruning as soon as they are planted.
