Coleonema pulchellum 'Compactum Red Velvet'

Red Velvet Diosma / Compact Pink Breath of Heaven

Botanical Name: Coleonema pulchellum ‘Compactum Red Velvet’
Family: Rutaceae
Origin: South Africa (garden cultivar selection)
Plant Type: Evergreen compact shrub

Overview

Coleonema pulchellum ‘Compactum Red Velvet’ is a neat, fine-textured evergreen shrub prized for its soft, aromatic foliage and masses of deep pink to red flowers that smother the plant from late winter through spring. Perfectly suited to Adelaide’s Mediterranean climate, it thrives in full sun, free-draining soils and low-water landscapes.

This compact form stays naturally dense and rounded, making it ideal for low hedging, borders, pots and feature plantings. The foliage releases a light citrus scent when brushed, adding another sensory layer to courtyards and pathways. With excellent drought tolerance once established and strong performance in coastal conditions, ‘Red Velvet’ is both beautiful and resilient.

Where It Works Best

• Sunlight: Full sun for best flowering and compact growth; tolerates light part shade
• Soil: Free-draining sandy or loamy soils; performs well on limestone soils common in Adelaide; avoid heavy, waterlogged clay
• Water Needs: Establishment: 2 deep soaks/week for 8–12 weeks; Established: deep soak every 10–14 days in summer (weekly in heatwaves); little to no water in winter
• Maintenance: Low — light prune after flowering to maintain shape and encourage density; avoid cutting into old woody growth; mulch annually
• Lifespan: 10–20+ years in suitable conditions
• Climate Zones: Ideal for temperate and Mediterranean South Australia — Adelaide Plains, Fleurieu Peninsula, coastal suburbs
• Soil pH: Neutral to slightly acidic preferred; tolerates mildly alkaline soils if drainage is excellent

Landscape & Design Ideas
