Chrysocephalum ramossisimum

Yellow Buttons / Spreading Everlasting

Botanical Name: Chrysocephalum ramosissimum
Family: Asteraceae
Origin: Australia (South Australia, Victoria, New South Wales)
Plant Type: Evergreen native groundcover / low spreading shrub

Overview

Chrysocephalum ramosissimum is a tough, low-growing Australian native valued for its soft silver-grey foliage and masses of bright golden-yellow “button” flowers. Naturally occurring in South Australia, it is perfectly adapted to Adelaide’s Mediterranean climate, thriving in heat, drought, wind and poor soils with minimal care.

Forming a dense, spreading mat, it works beautifully as a groundcover, edging plant or low filler in native, coastal and waterwise landscapes. Flowering heavily from spring through summer (often extending into autumn), it brings long-lasting colour and excellent pollinator value while remaining neat and non-invasive.

Key Features

• Mature Size: 0.2–0.4 m H × 0.8–1.5 m W (low, spreading habit)
• Growth Rate: 20–40 cm per year under good conditions
• Foliage: Soft, fine-textured silver-grey to grey-green leaves; evergreen; velvety appearance
• Flowers: Abundant bright yellow button-like blooms held above foliage; spring through summer, often extending into autumn
  
• Fragrance: Not fragrant
• Seasonal Interest: Evergreen silver foliage year-round with long-season yellow flowering
• Wildlife Value: Excellent nectar and pollen source for native bees, butterflies and beneficial insects
• Tolerance: Highly drought tolerant once established; excellent heat and wind tolerance; coastal tolerant (including exposed sites); light frost tolerant
• Planting Density: Groundcover: 1 plant per 1–1.5 m²; Edging or drift planting: 0.8–1 m apart
• Pet Friendly: Generally regarded as non-toxic

Where It Works Best

• Sunlight: Full sun for best flowering and compact growth (tolerates light part shade but flowers less)
• Soil: Free-draining sandy, loamy or gravelly soils; thrives in poor soils; avoid heavy or waterlogged clay
• Water Needs: Establishment: 2 deep soaks/week for 6-8 weeks; Established: deep soak every 3–4 weeks in summer; minimal water in winter
• Maintenance: Very low — light trim after flowering to maintain density and encourage fresh growth; avoid rich fertilisers
• Lifespan: 5–10+ years; easily refreshed with light pruning
• Climate Zones: Ideal for Mediterranean and temperate South Australia — Adelaide Plains, coastal suburbs, Fleurieu Peninsula, Yorke Peninsula
• Soil pH: Neutral to alkaline; tolerates slightly acidic soils if well drained

Landscape & Design Ideas

• Waterwise groundcover for native and coastal gardens
• Soft edging plant along paths, driveways and garden beds
• Mass planting on banks and slopes for erosion control
• Contrast plant among darker green foliage or bold natives
• Excellent filler between shrubs in low-maintenance landscapes

Why You Will Love It

Chrysocephalum ramosissimum is pure South Australian reliability—silver foliage, months of golden flowers, and outstanding toughness with almost no maintenance. Perfect for hot, dry gardens, it delivers colour, texture and pollinator value where many plants struggle.
