Layered planting is the technique that separates a designed garden from a planted one. You work in tiers: a tall evergreen backdrop, a mid-level structural layer, a low hedge, and feature trees that punctuate the composition with seasonal interest.
Done well, the result feels lush and considered in every season. Done badly, you end up with a wall of green that does nothing. The five trees below are the workhorses of layered design in Australian conditions.
Ficus Hillii - The Backdrop
Ficus Hillii is the benchmark Australian hedge tree. Fast, dense, glossy, and willing to be shaped into anything from a 2m garden screen to a 20m driveway wall. In a layered design, it goes at the back of the bed where its dark glossy foliage acts as a stage for everything in front.
Plant 800mm to 1m apart for a continuous hedge. Two or three clips a year keeps it crisp.
Magnolia grandiflora 'Little Gem' - The Mid Layer
Little Gem is the compact evergreen Magnolia. Glossy dark green leaves with rust-brown undersides, fragrant white summer flowers, and a naturally tidy form. In layered design it sits in the mid-layer, breaking up the flat plane of the Ficus backdrop with sculptural interest.
Can be pruned to desired height. Plant 2m apart if you want a screen, or singly as a feature.
Murraya paniculata - The Low Hedge
Murraya is the most popular fragrant hedge in Australia. White jasmine-scented flowers in flushes through the warm months, glossy mid-green foliage, and a naturally tidy form. In a layered design, it forms the low hedge that defines beds and pathways.
Plant 800mm apart. Avoid frost pockets in cold regions.
Lagerstroemia indica 'Natchez' - The Feature
Natchez is the white-flowered Crepe Myrtle that delivers a three-month summer flowering season, cinnamon-coloured sculptural bark, and reliable autumn colour. Plant as a feature in front of the Ficus backdrop where the white panicles and pale bark read brilliantly against dark glossy hedge.
Do not top-prune. Crepe Myrtle responds badly to heavy cutbacks. Light tip prune only.
Cercis canadensis 'Forest Pansy' - The Accent
Forest Pansy adds the burgundy that lifts the planting from pretty to refined. Heart-shaped foliage that emerges almost translucent rose, deepens to rich burgundy through summer, and finishes with apricot autumn tones. Plant as the accent that breaks up the green.
Stake young trees in their first year. Avoid windy positions.
Designing the Layers
Start at the back and work forward. The Ficus goes against the boundary, the Magnolia Little Gem forms the second tier 2m forward, the Murraya runs along the front edge, and the feature trees sit between the hedge layers where they have room to grow into shape.
Vary colour and texture between tiers. The Cercis burgundy against Ficus dark green, the Magnolia rust undersides against the Murraya bright green, the Crepe Myrtle white flowers against everything. That is what makes a layered planting read as designed.
Frequently Asked Questions
Can these trees work in smaller gardens?
Yes. All can be pruned to desired height. Use Murraya as the low hedge with Magnolia Little Gem as the only mid-tier, then a single feature tree.
How do I maintain a layered garden?
Two hedge clips a year for Ficus and Murraya, a light annual prune on the feature trees, and a yearly mulch. That is the routine.
Which tree gives the most seasonal interest?
Lagerstroemia 'Natchez' delivers three full seasons of show: flowers, autumn colour, and winter bark.
