Most of the planting advice online is written for somewhere else — temperate Melbourne courtyards, Sydney sandstone gardens, or worse, a British cottage border. The Sunshine Coast asks for something different. We get salt-laden easterlies off the ocean, humid summers that double as a fungal incubator, sandy or heavy-clay soils depending on the suburb, and a UV index that bleaches the wrong plant in a single season.
After hundreds of gardens between Mooloolah Valley, Buderim, Maleny and Noosa, we've narrowed our default palette to a small group of plants that keep performing — through cyclones, through heatwaves, through three Christmases of kids on the lawn. Below are five we plant on almost every project, with the honest reasoning for why they made the list, where to use them, and what to do if your site is the exception.
1. Lomandra Tanika — the workhorse grass
If we were only allowed one plant on the Sunshine Coast, this would be it. Lomandra 'Tanika' is a soft, weeping native grass that holds its shape in mass planting, copes with full sun or part shade, and shrugs off the dry weeks between summer storms. It's the plant we use to do the visual heavy lifting — sweeping it through garden beds, lining driveways, mass-planting on slopes where mowing is dangerous.
Plant it at 5 per square metre for a fast-knit mass, or 3 per square metre if you want each clump to read as an individual specimen. Cut it back to 100mm every two to three years to refresh the foliage — don't be precious about it.
- Mature size: 600mm high × 600mm wide
- Sun: full sun to part shade
- Water: low once established
- Best for: mass planting, slopes, around pools
2. Westringia fruticosa — coastal rosemary, the silver backbone
Westringia is the plant we reach for when a garden needs structure but not formality. The silver-grey foliage reads beautifully against dark mulch, charcoal Colorbond, or weathered timber. It clips well — into balls, into low hedges, into a softer cloud-pruned shape — and it tolerates the kind of sea spray that kills most ornamentals within a year.
Our preferred cultivar is 'Mundi' for low ground-cover work, and the straight species for hedging up to 1.2m. Both flower a soft mauve for most of the year and the bees love them.
Most failed coastal gardens fail because someone planted a plant that belongs in Sydney, in a Sunshine Coast easterly. Pick natives that evolved here.
3. Banksia integrifolia — the coast banksia
Few plants handle the immediate coast like Banksia integrifolia. It's wind-pruned naturally by the salt, develops a sculptural form over years, and feeds the lorikeets and honeyeaters all autumn and winter. We plant it on exposed boundaries where a tree is needed but a leafy non-native would be torn apart.
It does ask for one thing: free-draining soil. If you're on heavy clay, mound the planting hole 200mm above natural ground and backfill with a sandy loam blend. We've lost banksias to wet feet more often than to any other cause.
4. Frangipani (Plumeria rubra) — the sculptural anchor
Every Sunshine Coast garden deserves one frangipani. They drop their leaves in winter (don't panic), explode into flower in summer, and develop a gnarled, sculptural trunk that becomes the architectural centrepiece of the courtyard. The scent on a still January evening is the closest a plant gets to a holiday.
Plant them in full sun, in soil that drains, and don't overwater. The most common frangipani mistake we see is irrigation aimed at the trunk — it rots them out. Drip the bed, not the tree.
5. Dianella revoluta — the ground-level connector
Dianella is the plant that threads everything else together. A clumping native lily with strappy blue-green leaves and small purple flowers that turn into edible berries, it works at the front of a bed to soften the transition from path to planting, and it survives conditions that kill more refined groundcovers.
We mostly use 'Cassa Blue' for its tight clumping habit and consistent colour. It's the closest thing the coast has to a fail-safe.
How we put them together
A typical Coasta Valley coastal garden uses three of these five as the structural 70 per cent of the planting — usually Lomandra for the grass layer, Westringia for the mid-storey structure, and either Banksia or Frangipani as the canopy specimen. The remaining 30 per cent is where we add seasonal interest, edible plants, or the client's personal favourites.
Plant them in the cooler months (April to August) if you can. Mulch to 75mm with a coarse hardwood chip — not fine bark, which mats and sheds water. Water deeply twice a week for the first six weeks, then back off and let the roots chase the moisture down.
- 01The Sunshine Coast climate is harsher than online plant guides suggest — pick plants that evolved here.
- 02Lomandra Tanika, Westringia, Banksia integrifolia, Frangipani and Dianella revoluta form a low-fail planting palette.
- 03Drainage is the silent killer. Mound planting holes on heavy clay sites.
- 04Mulch deep with coarse hardwood, water hard early, then back off so roots dig down.
Frequently asked questions
When is the best time to plant on the Sunshine Coast?+
April through August. The soil is still warm enough to push root growth, but the heat and humidity that stress new plants have eased. We avoid planting between December and February unless we can guarantee daily watering.
How often should I water a new garden?+
Deeply twice a week for the first six weeks, then weekly for the next two months, then only in dry spells. Frequent shallow watering creates weak surface roots — exactly what you don't want in a coastal garden.
Do I need irrigation?+
For a planted-out garden, drip irrigation pays for itself in saved plants within the first dry season. We install drip on almost every job — it's invisible, efficient, and gives plants water at the root zone rather than the leaves.
Will these plants survive a cyclone?+
Established natives handle high winds better than almost any exotic. The damage we see after big weather is usually from poorly staked young trees, or from species like Magnolia and large-leaf exotics that catch the wind.
