Westringia fructicosa ‘Mundi’

Westringia fruticosa ‘Mundi’ - Coastal Rosemary Westringia 'Mundi' is a tough, low-growing Australian native shrub prized for its dense, spreading habit and exceptional versatility in the landscape. Forming a neat mound of soft grey-green foliage, it provides year-round colour and structure while requiring very little maintenance once established. Ideal for mass planting, borders, embankments, roadside plantings, and coastal gardens, 'Mundi' naturally grows wider than it is tall, creating an attractive groundcover that helps suppress weeds and stabilise soil. During spring and throughout the year, it produces delicate mauve to pale purple flowers that attract beneficial pollinators. Highly tolerant of drought, wind, salt spray, and a wide range of soil conditions, Westringia 'Mundi' is an excellent choice for Australian gardens seeking a hardy, water-wise planting solution. Position Westringia 'Mundi' performs best in full sun to part shade. For the densest growth and best flowering, choose a position that receives at least 6 hours of direct sunlight per day. It is highly adaptable and thrives in coastal locations, exposed sites, and gardens subject to wind and salt spray. This hardy native prefers well-drained soil but will tolerate a wide range of soil types, including sandy and clay-based soils once established. Avoid areas that remain consistently waterlogged. Growth As it matures, 'Mundi' typically reaches 40–60cm in height while spreading 1.5–2 metres wide, creating a dense canopy that helps suppress weeds and reduce soil erosion. Small mauve to pale purple flowers appear throughout the warmer months and often intermittently year-round, adding subtle colour and attracting bees and other beneficial pollinators. Planting Guide Westringia ‘Mundi’ grows best in well-drained soil enriched with organic matter. Space plants about 1 meter apart for hedging or group planting. For container planting, use a high-quality potting mix and position the container in a sunny or semi-shaded location. Water thoroughly after planting, and mulch around the base to retain moisture and suppress weeds. Plant Care Water regularly during the establishment phase, then reduce watering, as ‘Mundi’ is highly drought-tolerant once mature. Feed with a native-plant fertiliser in early spring to promote healthy growth and flowering. Prune lightly after flowering to maintain its shape and encourage dense growth. Mulching around the base helps retain soil moisture and protect roots during warmer months.
