Rhagodia spinescens ‘Silver Border’ is a low-growing, trailing form of the hardy Australian native Rhagodia spinescens. Selected for its compact, spreading habit and striking silvery-blue foliage, it forms a dense mat approximately 30 cm high and up to 2 meters wide, making it ideal for groundcover, mass planting, and erosion control. This cultivar thrives in harsh conditions, including coastal exposure, high salinity, and drought, while maintaining a clean, uniform appearance.
Uses:
- Low-maintenance groundcover for landscapes and public spaces
- Coastal and inland revegetation
- Erosion and weed control
- Contrast planting in native or Mediterranean-style gardens
- Low hedging or borders
- Suitable for green infrastructure projects (e.g. roadsides, swales)
Growing Conditions:
- Position: Full sun to part shade
- Soil: Wide range, including saline, sandy, loamy, and clay soils; must be well-drained
- Watering: Extremely drought-tolerant once established
- Frost tolerance: High
- Maintenance: Low; prune annually to maintain shape and density
- Fertiliser: Not typically required; low-phosphorus native fertiliser optional
Key Features:
- Naturally dense, spreading habit
- Silvery foliage provides year-round visual interest
- Salt and drought tolerant — ideal for tough sites
