Screen score is an editorial 1–5 suitability rating based on foliage persistence, density, training ease, mature size and maintenance. Height and spread are typical horticultural ranges; actual performance varies with climate, cultivar, pruning and support.

Fast Decision Guide

Need year-round privacy?

Start with Hardenbergia, star jasmine, Pandorea, Hibbertia or Cape honeysuckle. Avoid deciduous Wisteria and Campsis where winter screening matters.

Need a narrow fence screen?

Use disciplined twining plants on wires: Hardenbergia, Pandorea jasminoides, Pandorea pandorana or Mandevilla laxa. Keep laterals clipped to the fence plane.

Need maximum flower impact?

Bougainvillea, flame vine, passionflower and Campsis give the strongest seasonal display, but generally need more heat, space or control.

Need a native planting?

Choose Hardenbergia, Pandorea jasminoides, Pandorea pandorana, Hibbertia scandens or Kennedia rubicunda. Match species to local rainfall and frost exposure.

Need lower maintenance?

Hardenbergia, star jasmine and Hibbertia are easier to keep as screens than Wisteria, Campsis, passionflower or Japanese honeysuckle.

Need frost resilience?

Star jasmine, Solanum laxum, Japanese honeysuckle, Wisteria and Campsis tolerate colder conditions better than tropical or subtropical climbers.

Troubleshooting & FAQ

Why is my screen leafy at the top but bare at the base?

Apical growth has taken over. Fan young stems horizontally, tip-prune after flowering and renew one or two older stems at a time. Horizontal training activates more side shoots and improves density.

Why is flowering weak?

Common causes are insufficient sun, excess nitrogen, pruning at the wrong time or a support that encourages unchecked vertical growth. Check each plant's flower season before pruning.

Can climbers replace a conventional hedge?

Yes, when a permanent fence, trellis or wire framework is available. They create a thinner living screen than shrubs, but most cannot stand upright without support.

How far apart should Hardenbergia be planted?

For a dense trained screen, use roughly 1–1.5 metres between plants, then spread stems across the framework. Adjust spacing for cultivar vigour and how quickly you need coverage.

What should I check before planting a vigorous climber?

Confirm mature size, support strength, access for pruning, drainage, root space and local invasive-species rules. Avoid attaching heavyweight climbers to weak fences, gutters or fragile masonry.
