Overview

Many of us face a common challenge: we need a tall screen, but the space is limited. Narrow side yards, tight garden beds along driveways, and minimal planting spaces near fences can significantly restrict our choices of screening plants.

Maintenance issues can arise when screening plants begin to bulk up and encroach. In small gardens, they can become intrusive and reduce usable space. And across the fence, your neighbour may not share your enthusiasm, or responsibility, for keeping them in check.

Fortunately, tall and thin Australian native plants rise to the challenge. They provide a vertical structure that does not overwhelm tight spaces and offers aesthetic and functional qualities.

In this article, we’ve compiled a selection of tall plants for narrow spaces that offer more than just vertical height. These plants bring unique forms, rich textures, and seasonal colours, while responding well to pruning to remain dense and healthy.

16 Australian native screening plants for tight spaces

1. Callistemon viminalis ‘Slim’

Callistemon viminalis ‘Slim’ is among the best tall plants for narrow spaces thanks to its compact form, upright habit, and year-round visual appeal. This cultivar is a hybrid between ‘Captain Cook’ and another unnamed selection of Callistemon viminalis.

Reaching around 3 metres tall and just over 1 metre wide, it offers a vertical structure without encroaching on surrounding space. The arching branches and lance-shaped foliage bring softness and texture, while the vibrant red bottlebrush flowers attract birds and add seasonal colour.
