If you’re looking for a tough, evergreen shrub that delivers all-year-round beauty with minimal maintenance, the Westringia plant should be at the top of your list. Native to Australia’s coastal regions, this hardy shrub is admired for its versatility, drought tolerance, and attractive foliage. Whether you live near the sea, in a suburban garden, or even in warmer regions of India, Westringia adapts beautifully with the right care.
What is Westringia Plant?
Westringia Plant, commonly called Coastal Rosemary, is an Australian native shrub belonging to the mint family (Lamiaceae). Despite its common name, it’s not a true rosemary, though its foliage and scent might remind you of it. The plant features fine, grey-green leaves arranged in neat whorls around the stems and produces small, delicate flowers, usually shades of white, blue, or mauve, throughout almost the entire year.
Its natural tolerance to salt-laden winds, drought, and poor soils makes Westringia a gardener’s favorite, particularly in coastal or low-water landscapes.

Where Should I Plant My Westringia?
Westringia adapts well to a range of environments, but choosing the right spot ensures optimal health and flowering.

- Exposure: Perfect for coastal and windy sites, Westringia Plant can handle salt spray better than most shrubs.
- Spacing: For hedges, plant 50–100 cm apart, depending on the variety.
For Indian gardeners, pick a slightly shaded area if your region faces harsh afternoon sun. Ensure the soil doesn’t remain soggy after rains.
Which Westringia Is Best for My Needs?
| Purpose | Recommended Variety | Key Benefit |
|---|---|---|
| Formal Hedge | Westringia Grey Box, Wynyabbie Gem | Dense foliage, easy to shape |
| Ground Cover | Westringia Mundi, Low Horizon | Low-growing, erosion control |
| Feature Plant | Westringia Blue Gem, Morning Light | Striking flowers or variegated foliage |
| Coastal Garden | Westringia Fruticosa, Smokey | Excellent salt and wind tolerance |
| Compact Pots/Small Spaces | Westringia Grey Box | Neat growth habit |
How Should I Prune My Westringia?
Pruning Westringia keeps it neat, dense, and encourages more flowering. It’s a forgiving shrub that responds well to regular trimming.
When to Prune
- Light pruning: After flowering in spring or early summer.
- Hard pruning: Every 2–3 years to rejuvenate older plants.
Pruning Tips
Apply a slow-release native fertilizer after pruning to boost regrowth.
Use clean, sharp shears.
Trim lightly after flowering to shape the plant.
For hedges, shear uniformly but avoid cutting into old wood.
In India, where Westringia may flower nearly year-round, you can prune lightly 2–3 times annually to maintain its shape and encourage healthy foliage.
The Challenge: Westringia in Heavy Clay Soils
While Westringia is tolerant of many soil types, heavy clay can be problematic due to poor drainage. This can lead to root rot or stunted growth.
How to Overcome Clay Soil Issues
- Improve Drainage: Mix coarse sand, compost, and gypsum into the soil.
- Raised Beds or Mounds: Plant your Westringia slightly above ground level to prevent waterlogging.
- Avoid Overwatering: Let the soil dry out between watering cycles.
- Container Planting Option: In very dense clay soils, grow Westringia in large pots with a native mix for better control.
