Cenchrus purpurascens 'Nafray'

Nafray Fountain Grass / Purple Fountain Grass

Botanical Name: Cenchrus purpurascens ‘Nafray’
Family: Poaceae
Origin: Africa (cultivar selection)
Plant Type: Evergreen to semi-evergreen ornamental grass

Overview

Perfectly suited to Adelaide’s warm, dry Mediterranean climate, Cenchrus purpurascens ‘Nafray’ is a compact, highly ornamental fountain grass valued for its arching burgundy-green foliage and soft, smoky-purple flower plumes. Smaller and tidier than traditional purple fountain grass, it delivers strong colour, texture and movement without becoming overpowering. Flowering from late spring through autumn, it provides long seasonal interest in borders, mass plantings and containers. Heat-loving, drought-tolerant once established and adaptable to coastal conditions, ‘Nafray’ is a reliable performer in South Australian landscapes, especially where low maintenance and bold contrast are desired.

Key Features

• Mature Size: 0.6–0.9 m H × 0.6–0.8 m W (compact, arching clump)
• Growth Rate: 20–40 cm per year under good conditions
• Foliage: Narrow, arching leaves in deep burgundy to purple-green; colour intensifies in full sun and warm weather, softening slightly in winter
• Flowers: Soft bottlebrush-like plumes in smoky purple to rose tones from late spring through autumn
  
• Fragrance: Not fragrant
• Seasonal Interest: Strong foliage colour from spring through autumn, with airy flower plumes adding movement; semi-evergreen structure through mild Adelaide winters
• Wildlife Value: Provides shelter for small insects; seed heads may attract birds late in the season
• Tolerance: Drought-tolerant once established; excellent heat tolerance; wind tolerant; suitable for coastal gardens (second-line); light frost hardy but foliage may brown briefly in colder winters
• Planting Density: Mass planting: 3–5 plants per m²; borders: 60–80 cm apart; containers: 30–40 cm pots
• Pet Friendly: Generally regarded as non-toxic

Where It Works Best

• Sunlight: Full sun for best colour and flowering; tolerates very light part shade with reduced intensity
• Soil: Well-drained sandy, loamy or improved clay soils; tolerates Adelaide’s slightly alkaline conditions; avoid prolonged waterlogging
• Water Needs: Establishment: 2 deep soaks/week for 6–8 weeks. Established: deep soak every 10–14 days in summer; minimal watering in winter
• Maintenance: Very low; cut back old foliage in late winter to refresh growth; remove spent flower heads if a tidier look is desired; avoid high fertiliser inputs
• Lifespan: 5–10+ years in well-drained conditions
• Climate Zones: Ideal for Mediterranean and temperate South Australia — Adelaide Plains, coastal suburbs, Fleurieu Peninsula, Yorke Peninsula
• Soil pH: Neutral to slightly alkaline; tolerant of mildly acidic soils if well drained

Landscape & Design Ideas

• Modern and Mediterranean gardens needing bold foliage contrast
• Mass planting for rhythm and movement in large beds
• Feature grass for courtyards and alfresco containers
• Coastal and heat-exposed sites where colour and toughness are essential
• Pairs beautifully with salvias, lomandra, lavender, westringia and succulents

Why You Will Love It
