Trachelospermum jasminoides 'Tricolor'

Variegated Star Jasmine

Botanical Name: Trachelospermum jasminoides 'Tricolor'
Family: Apocynaceae
Origin: East Asia (China, Japan, Korea)
Plant Type: Evergreen self-twining groundcover or climber

Overview

Trachelospermum jasminoides 'Tricolor' is a stunning variegated form of the ever-popular Star Jasmine, treasured for its year-round kaleidoscope of foliage colour rather than relying solely on its flowers. New growth emerges in flushes of soft pink and creamy white before maturing into a rich green base mottled with pink and cream — a living tapestry of colour across every season. Wonderfully versatile, it sprawls elegantly as a low groundcover, twines up a trellis or fence, or clips neatly to a low stepover hedge, all while perfuming the garden with sweetly scented white star flowers in spring and summer.

Key Features

• Mature Size: 0.5 m H × 1.5–2 m W as a groundcover; up to 1.5–3 m W as a supported climber
• Growth Rate: Slow; approximately 10–20 cm per year; noticeably slower than the plain species, with a dense, self-twining habit that builds steadily into a tidy, layered mat or low vine — patience rewarded with exceptional year-round colour
• Foliage: Glossy, rounded-oval leaves in deep green splashed with irregular markings of white, copper-tan and pink; new growth emerges vividly pink to creamy white and ages to mottled green-pink-cream; colour intensity varies plant to plant and season to season, with the most vivid tones in spring and autumn
• Flowers: White, star-shaped (pinwheel form), produced in loose terminal clusters; strongly sweet-jasmine fragrant; spring through summer (September–January in South Australia); flowers more sparingly than the plain species but still highly perfumed
• Seasonal Interest: Continuous four-season foliage interest — pink-flushed new growth in spring, summer green with cream-white margins, copper-tan autumn tones deepening to burgundy-pink in cool winter months
• Wildlife Value: Fragrant flowers attract bees, hoverflies, butterflies and other nectar-feeding pollinators; dense mat foliage provides shelter for beneficial insects; noted as a nectar source for small birds
• Tolerance: Drought-tolerant once established (moderate dry spells); light frost tolerant in sheltered gardens (marginal to −3 °C); heat-tolerant in SA conditions when mulched; coastal-tolerant with protection from direct salt spray; wind-tolerant (medium exposure); adapted to a wide range of soils including light clay if drainage is adequate
• Planting Density: Groundcover — tight/weed-suppressing carpet: 50 cm apart (4 plants/m²); groundcover — standard/relaxed coverage: 75 cm apart (1–2 plants/m²); stepover hedge or border edging: 60 cm apart in a single row; climber on trellis or fence: 80–100 cm apart per linear metre
• Pet Friendly: Mildly toxic to dogs and cats — the Apocynaceae family contains latex sap and trace alkaloids that can cause mild gastrointestinal upset (drooling, vomiting) if foliage or stems are chewed in quantity. Not typically life-threatening, but plant out of reach of pets that habitually chew foliage; contact your vet if significant ingestion is suspected.

Where It Works Best

• Sunlight: Full sun to part shade; foliage variegation is most vivid and pink tones most intense in a bright position with some afternoon shade in Adelaide's hot summers; tolerates more shade than the plain species but may produce fewer flowers in deep shade
• Soil: Adaptable to most well-drained soils — loam, sandy loam, sandy soils enriched with organic matter; tolerates light clay if not waterlogged; avoid poorly drained or compacted heavy clay; enrich planting hole with compost and apply a 7 cm chunky organic mulch layer
• Water Needs: Establishment (first 12–16 weeks): water deeply 2–3 times per week, keeping soil evenly moist but not waterlogged; mulch immediately to retain moisture. Established: summer — water deeply once per week during dry spells (every 10–14 days with mulch in place); winter — reduce to once per fortnight or rely on rainfall; brief dry periods are tolerated once the root system is well anchored
• Maintenance: Very low; prune lightly after the main spring–summer flowering flush to encourage bushy new growth and maintain desired form; responds well to hard clipping if used as a stepover hedge; apply a balanced slow-release fertiliser in early spring; inspect occasionally for scale insects in humid conditions
• Lifespan: Long-lived; 20+ years in suitable conditions
• Climate Zones: Suited to Adelaide's temperate and Mediterranean climate; performs well across the Adelaide Plains, inner suburbs, coastal and near-coastal zones, and sheltered Hills foothills gardens; marginal in exposed Hills positions with hard frosts below −3 °C — site in a protected north or west-facing aspect; ideal for Barossa Valley, Clare Valley, McLaren Vale and Fleurieu Peninsula gardens; also well-suited to Adelaide CBD courtyard and rooftop planting
• Soil pH: Tolerates a wide range — acid to alkaline (pH 5.5–8.0); performs best in slightly acidic to neutral (pH 6.0–7.0); tolerates the alkaline soils common on Adelaide's limestone-influenced plains

Landscape & Design Ideas

• Weed-suppressing groundcover: Plant 50–75 cm apart beneath deciduous trees, along sunny embankments or over difficult slopes to create a dense, evergreen, colour-rich mat that crowds out weeds and requires minimal mowing or spraying — a low-maintenance solution for Adelaide Hills and suburban garden beds alike.
• Colourful fence or trellis cover: Train onto wire trellis, timber lattice or Colorbond fence panels spaced 80–100 cm apart; the slow, self-twining habit builds a dense, layered screen with the bonus of scented spring flowers — perfect for softening boundary fences in inner-Adelaide courtyards and alfresco zones.
• Stepover hedge or decorative border edging: Plant 60 cm apart in a single row and clip twice yearly to form a neat low edging hedge 30–50 cm high along pathways, driveways or garden bed borders — the tricoloured foliage provides year-round visual interest unlike plain green hedging alternatives.

Why You Will Love It

Trachelospermum jasminoides 'Tricolor' is the rare garden plant that earns its place 365 days a year — not just for its sweetly perfumed spring flowers, but for its extraordinary living tapestry of pink, cream, copper and green foliage that shifts and evolves through every season. Tougher than it looks, this slow-growing gem thrives in Adelaide's hot, dry summers with minimal fuss once established, and suits everything from a fragrant alfresco screen to a weed-smothering groundcover or an ornamental stepover hedge. If you want a plant that gives your garden effortless colour, scent, and structure with very little back from you — this is it.
