Scabiosa columbaria 'Mariposa Blue'

Mariposa Blue Pincushion Flower

Botanical Name: Scabiosa columbaria ‘Mariposa Blue’
Family: Caprifoliaceae
Origin: Europe, North Africa & Western Asia (cultivar selection)
Plant Type: Evergreen to semi-evergreen perennial

Overview

A refined, long-flowering Scabiosa perfectly suited to Adelaide’s Mediterranean climate, Scabiosa columbaria ‘Mariposa Blue’ produces masses of soft lavender-blue pincushion blooms with delicate ruffled edges, creating an airy, romantic display from late spring through autumn. Compact, upright and gently mounding, it fits beautifully into mixed borders, cottage gardens, low-water landscapes and pots. The foliage is fine-textured and mid-green, often developing silvery, blue-green or soft purple tints during cold weather or dry spells. While not considered fragrant, the flowers may have a faint sweet floral scent when inspected closely. Highly attractive to pollinators and tolerant of heat and dryness once established, it thrives in SA’s warm, dry summers so long as the soil is free-draining.

Where It Works Best

• Sunlight: Full sun for strongest flowering and best plant shape; tolerates light part shade with reduced bloom
• Soil: Free-draining sandy or loamy soils; thrives in slightly alkaline soils common across Adelaide
• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks. Established: deep soak every 10–14 days in summer; minimal water in winter
• Maintenance: Remove spent flowers to extend blooming; trim lightly in late winter to maintain shape; avoid high-nitrogen fertilisers which encourage leafy growth over flowers
• Lifespan: 3–6+ years in well-drained conditions; can be renewed by division every 2–3 years
• Climate Zones: Excellent for Mediterranean and temperate SA — Adelaide Plains, foothills, Fleurieu Peninsula, Yorke Peninsula, coastal suburbs
• Soil pH: Neutral to alkaline preferred; tolerates slightly acidic soils if drainage is excellent

Landscape & Design Ideas
