Enchylaena tomentosa

Ruby Saltbush / Barrier Saltbush

Botanical Name: Enchylaena tomentosa
Family: Chenopodiaceae
Origin: Australia
Plant Type: Evergreen to semi-evergreen low shrub / groundcover

Overview

Perfectly adapted to Adelaide’s dry, Mediterranean climate, Enchylaena tomentosa is a tough, low-growing Australian native prized for its soft grey-green foliage and striking ruby-red to pink edible berries. Naturally occurring across much of arid and semi-arid Australia, it thrives in heat, poor soils, wind and low rainfall, making it an excellent choice for South Australian gardens focused on resilience and water efficiency. Its spreading, mound-forming habit works beautifully as a groundcover, low informal edging or filler plant in native, coastal and low-maintenance landscapes. While not fragrant, the foliage has a soft, felted texture and may develop subtle silvery or blue-grey tints during dry periods, adding understated year-round interest.

Key Features

• Mature Size: 0.3–0.6 m H × 1–2 m W (low, spreading habit)
• Growth Rate: 20–40 cm per year under good conditions
• Foliage: Soft, rounded grey-green leaves with a felted texture; foliage may take on silvery or bluish tints in dry, exposed or coastal conditions
• Flowers: Small, inconspicuous greenish flowers followed by decorative ruby-red to pink fleshy berries from late winter through summer
  
• Fragrance: Not fragrant
• Seasonal Interest: Evergreen structure year-round with colourful berries providing interest from late winter through summer; foliage colour remains attractive through dry periods
• Wildlife Value: Berries attract birds; dense growth provides shelter for small reptiles and beneficial insects
• Tolerance: Extremely drought tolerant once established; excellent heat, wind and coastal tolerance; salt tolerant; light frost hardy; thrives in poor, sandy or rocky soils
• Planting Density: Groundcover use: 1 plant per 1.5–2.5 m²; informal edging or mass planting: 1–1.5 m apart
• Pet Friendly: Generally regarded as non-toxic; berries are edible for humans and wildlife

Where It Works Best

• Sunlight: Full sun to light part shade; best form and berry production in full sun
• Soil: Free-draining sandy, loamy or limestone soils; tolerates poor, saline and alkaline soils; avoid prolonged waterlogging
• Water Needs: Establishment: 1–2 deep soaks/week for 6–8 weeks. Established: very low water needs; occasional deep watering during extended heatwaves only
• Maintenance: Very low; prune lightly if shaping is required; no regular feeding needed; avoid rich fertilisers
• Lifespan: 10–20+ years in well-drained conditions
• Climate Zones: Ideal for arid, semi-arid, temperate and Mediterranean South Australia — Adelaide Plains, coastal suburbs, Fleurieu, Yorke and Eyre Peninsulas
• Soil pH: Neutral to alkaline; highly tolerant of alkaline and saline soils

Landscape & Design Ideas

• Waterwise native groundcover for dry gardens and nature strips
• Coastal and salt-exposed landscapes where other plants struggle
• Informal edging or filler plant in native and Mediterranean designs
• Habitat gardens supporting birds and small fauna
• Low-maintenance mass plantings paired with Westringia, Atriplex, Eremophila and native grasses
