Mat Rush 'Katrinus Deluxe'

Botanical Name: Lomandra longifolia 'Katrinus Deluxe'
Family: Asparagaceae
Origin: Australia
Plant Type: Strappy grass-like perennial

Overview

A robust, landscape-grade lomandra that stays neat in Adelaide and South Australian conditions. ‘Katrinus Deluxe’ forms dense, fresh mid-green clumps that handle heat, wind and coastal exposure once established. Subtle spring flowers add a soft native look while the foliage gives year-round structure with minimal fuss.

Key Features

• Mature Size: 0.5-0.8 m H x 0.6-0.9 m W
• Growth Rate: 20-30 cm per year under good conditions
• Foliage: Fresh mid-green, strappy leaves in neat clumps — new growth lime-green before deepening; in cool winters foliage can read deeper blue-green; in hot/dry spells tips may show olive/bronze on older blades (normal)
• Flowers: Subtle cream spikes in spring–summer, lightly fragrant up close
• Seasonal Interest: Evergreen mounds provide year-round structure; spring flowers and seedheads add soft texture and movement
• Wildlife Value: Supports local biodiversity—dense clumps offer shelter; flowers feed pollinators
• Tolerance: Drought-Tolerant (once established), Heat-Tolerant, Frost Hardy (light–moderate), Coastal-Tolerant with good drainage, Wind-Tolerant; Clay-Tolerant in free-draining clay/loam
• Planting Density: Mass planting: 2–3 plants per m². Edges/drifts: 1–2 plants per linear metre
• Pet Friendly: Non-toxic to cats and dogs, avoid deliberate ingestion.

Where It Works Best

• Sunlight: Full sun to part shade
• Soil: Well-drained loam, sandy loam or clay loam
• Water Needs: Establishment: 2 deep soaks/week for 8-12 weeks. Established: deep soak every 10-14 days in summer; monthly in winter if dry.
• Maintenance: Mulch in spring; comb or lightly trim tired foliage in late winter/early spring; remove spent flower stems; use a low-phosphorus/native-safe feed in early spring
• Lifespan: 15-25 years
• Climate Zones: Suited to temperate and Mediterranean SA gardens, including coastal areas
• Soil pH: Slightly acidic to mildly alkaline with good drainage

Landscape & Design Ideas

• Define paths and driveways with a continuous ribbon of texture and movement
• Mass plant on banks or hot, dry strips for a drought-smart, weed-suppressing groundcover
• Feature near entries and outdoor living spaces; great in modern coastal schemes and large pots
