Serenity Purple African Daisy
Botanical Name: Osteospermum ecklonis ‘Serenity Purple’
Family: Asteraceae
Origin: South Africa
Plant Type: Evergreen perennial (short-lived in very hot or wet areas)
Overview
A high-impact, sun-loving daisy well suited to Adelaide’s Mediterranean climate, Osteospermum ‘Serenity Purple’ delivers masses of rich purple blooms with subtle lavender and violet tones. Flowering from late winter through spring, with another flush in autumn, it brings dependable, long-season colour to borders, coastal gardens, cottage beds, and pots. Compact, neat and drought-tolerant once established, it performs beautifully in South Australia’s dry summers when grown in free-draining soil.
Key Features
- Mature Size: 0.25–0.35 m H × 0.4–0.6 m W

-
Fragrance: Not considered fragrant — flowers have no noticeable scent.
- Seasonal Interest: A long flowering season with intense purple colour in spring and autumn; evergreen or semi-evergreen foliage provides year-round structure and subtle tint changes in cooler months
- Wildlife Value: Attracts bees, butterflies, hoverflies and other beneficial pollinators throughout the flowering season
- Tolerance: Drought- and heat-tolerant once established; handles coastal exposure and wind; light frost-tolerant; prefers low humidity and good drainage, making it ideal for most Adelaide soils except heavy, wet clay

- Pet Friendly: Non-toxic to cats and dogs
Where It Works Best
- Sunlight: Full sun is essential for strongest colour and heaviest flowering; tolerates slight afternoon shade in very hot inland areas
- Soil: Prefers free-draining sandy or loamy soils; avoid chronically wet areas
- 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: Remove spent flowers for continuous bloom; lightly trim after the main flush; avoid high-nitrogen fertilisers which reduce flowering
- Lifespan: 5–8 years in well-drained conditions
- Climate Zones: Perfect for Mediterranean and temperate SA regions — including Adelaide, the Fleurieu Peninsula, Yorke Peninsula, and coastal areas
- Soil pH: Neutral to slightly alkaline soils preferred
Landscape & Design Ideas
- Coastal & Beachside Gardens: Handles salt, wind, and poor sandy soils
- Rock Gardens & Path Edges: Ideal for adding vibrant colour with minimal water
- Mixed Flower Borders: Pair with Salvia, Lavender, Gazania, Leucophyta, and other dry-climate perennials
