Botanical Name: Mandevilla hybrid 'Aloha Red & White' Mix
Family: Apocynaceae

Plant Type: Climber & Vine

Overview

A stunning two-tone mandevilla mix perfect for Adelaide and South Australian courtyards, balconies and warm garden walls. This collection combines bold red trumpets with pure white blooms (both with golden throats) for months of tropical colour in warm weather over glossy foliage. Naturally tidy and easy-care, it delivers a lush, resort feel in pots or in-ground with simple support and regular summer watering.

Key Features

• Mature Size: 1.8–3 m H × 1–1.5 m W (climbing/twinning; smaller in pots)
• Growth Rate: 30–60 cm per year under good conditions
• Foliage: Glossy mid-green, oval leaves; new growth lime-green before deepening; in strong sun/cool nights older leaves can show bronze/olive tints (normal); foliage remains evergreen in mild winters
• Flowers: Large, vivid red and pure white trumpets with yellow throats, spring through autumn; creates a striking bicolour display
• Fragrance: Lightly fragrant on warm evenings; sweet, subtle scent
• Seasonal Interest: Long flowering window (spring–autumn) over evergreen foliage; peak display late spring–summer
• Wildlife Value: Excellent for pollinators—nectar draws bees, butterflies, and beneficial insects
• Tolerance: Heat-tolerant; coastal-tolerant (sheltered sites); frost-tender (light frosts mark foliage—protect below 0 °C); wind: shelter from hot, drying winds; requires regular moisture in hot spells and free-draining soil
• Planting Density: Trellis/fence: 1 plant per 1–1.5 m; pots/columns: one plant per support
• Pet Friendly: Use caution—milky sap can irritate skin; ingestion may cause mild GI upset. Keep prunings away from pets

Where It Works Best

• Sunlight: Full sun to part shade (4–6+ hours sun; afternoon shade helps in inland SA heat)
• Soil: Well-drained loam or sandy loam; improve clay with organic matter/grit; excellent in premium potting mix
• Water Needs:
  • Establishment: Deep soak twice weekly for 8–12 weeks
  • Established: Keep evenly moist; deep soak every 7–10 days in summer (2–3×/week in heatwaves or for containers); monthly in winter if dry
• Maintenance: Feed in spring and midsummer with a bloom fertiliser; tip-prune to keep bushy; tie in new shoots; deadhead spent clusters to encourage continuous flowering; mulch in spring; prune after flowering or late winter to refresh; trim lightly to maintain shape
• Lifespan: 5–10+ years with proper care
• Climate Zones: Suited to temperate & Mediterranean SA; best in Adelaide's warm, sheltered microclimates and coastal areas
• Soil pH: Slightly acidic to neutral (pH 6.0–7.0); tolerates mildly alkaline if drainage is sharp

Landscape & Design Ideas

• Privacy screening on trellis/strings for a vertical splash of red and white
• Entrance pots/obelisks for months of bicolour impact by the front door
• Sunny courtyards and balcony walls for a lush, tropical vibe
• Mixed planting with complementary foliage plants like cordylines or agapanthus
• Feature climber on pergola posts or decorative garden structures
