Cordyline australis Chocolate Mint

Experience the breathtaking beauty of Cordyline australis ‘Choc Mint’, one of the most spectacular and dramatically coloured evergreen architectural plants for gardens, where extraordinary chocolate-brown to deep burgundy sword-shaped leaves with striking pink-cream margins, bold exotic palm-like form, and year-round presence combine to create stunning displays of architectural drama and exceptional colour contrast that bring months of dark dramatic foliage with luminous variegation and reliable evergreen structure with remarkable intensity making this perfect for adding exotic focal points, bold colour contrast, and architectural presence to mixed borders, contemporary gardens, and containers where exceptional variegation and tropical effect are essential. This exceptional cultivar offers remarkable qualities—extraordinary chocolate-brown to deep burgundy foliage with striking pink-cream to coral-pink margins creating one of the most dramatic colour combinations of any cordyline, bold sword-shaped leaves arranged in rosettes creating exotic palm-like architectural form, outstanding year-round evergreen presence providing constant structure and colour, eventual development of distinctive trunk creating tree-like form with age, and good hardiness thriving in most of UK and Ireland with reasonable winter protection, making this one of the most rewarding and striking choices for adding exotic drama, bold variegated colour, and architectural presence to gardens.

Throughout the seasons, this captivating architectural plant displays spectacular year-round interest—the foliage is the primary ornamental feature providing constant presence in all seasons. The leaves are long, narrow, and sword-shaped (linear-lanceolate), measuring 40-90cm long and 2-4cm wide with smooth edges and pointed tips creating dramatic architectural effect. The leaves are arranged in dense rosettes radiating from central growing point creating fountain-like or palm-like form. The leaf colour is the cultivar’s most spectacular feature—each leaf has chocolate-brown to deep burgundy to dark bronze-brown centre with striking pink-cream to coral-pink to rose-pink margins measuring 3-5mm wide creating extraordinary contrast. The dark chocolate-brown centre colour is rich and intense—significantly darker than most cordylines. The pink-cream margins are luminous and striking—the colour is most intense on young emerging leaves and in full sun, creating vibrant contrast against the dark centres. The variegation is consistent along entire leaf length creating bold striped effect. The overall effect is dramatic and exotic—the combination of dark chocolate-brown and bright pink-cream creates one of the most striking colour contrasts available in foliage plants. The foliage is evergreen, providing year-round presence—in winter, the colours may intensify slightly in cold weather. Young plants form dense basal rosettes 60-90cm tall. As plants mature (typically after 3-5 years), they develop distinctive trunk—the lower leaves gradually die and fall, revealing smooth grey-brown trunk topped by rosette of leaves creating palm-like tree form. Mature specimens can reach 2-3m tall with single or occasionally branched trunks. On mature specimens (typically 5+ years old), fragrant creamy-white flowers may be produced in summer (June-July)—the flowers are arranged in large branched panicles measuring 60-120cm long arching above foliage creating spectacular displays. The flowers are sweetly fragrant, particularly in evenings. Following flowering, small white berries may develop. However, flowering is not common on younger specimens and is not the primary ornamental feature. The growth habit is upright and architectural—young plants form dense rosettes, while mature plants develop distinctive palm-like form with trunk and crown. Growth is slow to moderate, adding 15-30cm annually. The overall effect is exotic, dramatic, and architecturally striking—like having tropical palm-like presence with extraordinary chocolate-brown and pink-cream variegated foliage creating bold focal points with year-round interest.

Native to New Zealand where Cordyline australis (cabbage tree or ti kouka) grows wild in forests, wetlands, and coastal areas, this species has been cultivated in European gardens since the 19th century for its exotic architectural form. The genus name Cordyline comes from the Greek ‘kordyle’ (club), referring to the enlarged underground roots. The species name ‘australis’ means “southern,” referring to its Southern Hemisphere origins. ‘Choc Mint’ is a modern cultivar specifically selected for exceptional chocolate-brown to deep burgundy foliage with striking pink-cream margins creating dramatic colour contrast (one of the darkest and most colourful cordylines), bold architectural form creating exotic presence, good garden performance, and reasonable hardiness. This represents one of the finest dark variegated cordylines—the chocolate-brown and pink-cream combination is particularly striking and unique. Hardy to RHS H4, this reasonably robust plant thrives in most of UK and Ireland, particularly in coastal and mild areas, tolerating temperatures to around -5°C to -10°C. In colder areas or exposed positions, winter protection may be needed. Slow to moderate growth rate, forming substantial specimens within 5-10 years. Particularly valuable for extraordinary chocolate-brown foliage with striking pink-cream margins creating dramatic colour contrast, bold exotic palm-like architectural form, year-round evergreen presence, eventual trunk development creating tree-like form, and good performance in coastal gardens. The dramatic variegation and exotic form make this outstanding for contemporary gardens, tropical-style plantings, and containers.

Create stunning compositions by planting as focal points in mixed borders where the exotic form and dramatic variegation create architectural presence and bold contrast, using in contemporary gardens and minimalist landscapes where the sculptural form provides striking architectural interest, or positioning in containers creating spectacular portable displays for patios, entrances, courtyards, and roof gardens. Exceptional in tropical-style and exotic plantings combined with other architectural plants (phormiums, yuccas, palms, tree ferns, bananas) creating lush dramatic displays, in coastal gardens where the salt tolerance and wind resistance ensure success, or in gravel gardens where the architectural form creates focal points against neutral backgrounds. Works beautifully combined with contrasting foliage colours—silver foliage plants (Artemisia, Stachys, Convolvulus cneorum) for sophisticated combinations, golden foliage plants (Choisya ‘Sundance’, Carex ‘Evergold’) for warm vibrant contrast, or lime-green foliage (Heuchera ‘Lime Marmalade’, Hakonechloa ‘Aureola’) for fresh contrast. Also magnificent combined with other architectural plants (Phormium ‘Pink Stripe’, Yucca filamentosa, Fatsia japonica) for varied exotic forms, ornamental grasses (Miscanthus, Pennisetum, Stipa) for textural contrast and movement, or hot-coloured perennials (Crocosmia, Hemerocallis, Kniphofia) that echo the pink tones in the variegation. Perfect for adding exotic drama, bold variegated colour, and architectural presence to mixed borders, contemporary gardens, tropical plantings, coastal gardens, and containers. Stunning focal point and conversation piece!

Planting: Space plants 1.5-2m apart for individual specimens—these are architectural focal points best planted singly or in small groups. Plant container-grown specimens in spring (April-May) for best establishment, allowing full growing season before first winter. Autumn planting is possible in mild areas. Choose position in full sun to partial shade—full sun produces most intense chocolate-brown colour and brightest pink-cream margins, while partial shade produces slightly less intense colours but still attractive. Shelter from cold drying winds which can damage foliage—position in protected locations, sheltered borders, or against warm walls, particularly in colder areas. Thrives in coastal gardens with excellent salt and wind tolerance. Avoid frost pockets and exposed positions in cold areas. Dig generous planting hole twice width of root ball and same depth. Requires well-drained soil—avoid waterlogged conditions which cause root rot. Incorporate grit or sharp sand into heavy soils to improve drainage. Plant at same depth as in container, ensuring root ball is level with surrounding soil. Backfill carefully, firming gently. Water thoroughly after planting. Apply 5-8cm mulch around base, keeping mulch clear of crown (5cm gap). Water regularly during first growing season. In cold areas (RHS H4 borderline), provide winter protection for first 2-3 winters until established—wrap crown with horticultural fleece or straw during severe cold spells. Position where the exotic form and dramatic variegation can be appreciated year-round.

Soil Preparation: Prefers well-drained, moderately fertile soil for best growth. Tolerates wide pH range from slightly acidic to alkaline (pH 6.0-8.0). Thrives in wide range of soil types including sandy, loamy, and even poor soils provided drainage is excellent. CRITICAL: Requires excellent drainage—waterlogged conditions cause root rot and death, particularly in winter. Avoid heavy clay soils unless drainage is improved. Tolerates poor, dry, and sandy soils once established—excellent for coastal gardens and free-draining sites. Thrives in moderately fertile soils—excessively rich soils can cause soft lush growth more susceptible to frost damage. Improve heavy clay soils by incorporating generous amounts of grit or sharp sand to improve drainage. Improve light sandy soils by adding moderate amounts of compost to improve fertility. Mulch lightly in spring, keeping mulch clear of crown. Best growth and colour occur in full sun with well-drained, moderately fertile soil—these conditions produce the most intense chocolate-brown colour and brightest pink-cream margins.

Container Growing: Excellent for container growing—one of the finest architectural plants for pots! Use containers with excellent drainage holes (minimum 40-50cm diameter for established plants), soil-based compost (John Innes No. 2 or No. 3) mixed with extra grit for drainage, and position in full sun to partial shade in sheltered location. Water regularly during growing season—allow compost surface to dry slightly between waterings, never waterlog. Feed monthly during growing season (April-September) with balanced liquid fertiliser. No pruning required. Top-dress annually with fresh compost. Repot every 3-5 years in spring using fresh compost and slightly larger container. IMPORTANT: Move containers to sheltered positions (against walls, under eaves, into unheated greenhouse or conservatory) during winter in cold areas to protect from severe frost. Perfect for creating exotic drama on patios, courtyards, and entrances! The dramatic variegation and architectural form are stunning in decorative containers.

Seasonal Care: Very low maintenance! No pruning required—naturally maintains attractive form. Remove any dead or damaged leaves by pulling gently downward or cutting at base with sharp secateurs—this keeps plant tidy. As plant matures and develops trunk, lower leaves naturally die and can be removed to reveal trunk. Apply slow-release balanced fertiliser in spring around base if desired, though established plants require minimal feeding. Mulch lightly in spring, keeping mulch clear of crown. Water during prolonged dry spells, particularly during first 3-5 years of establishment and for container specimens—once established, plants are reasonably drought-tolerant. WINTER PROTECTION IN COLD AREAS: In RHS H4 borderline areas or during severe winters, protect crown during coldest months (December-February)—tie leaves loosely together in upright bundle and wrap with horticultural fleece or hessian, or stuff centre with dry straw or bracken. Remove protection in spring (March-April). Container specimens should be moved to sheltered positions during winter. Generally pest and disease free with excellent vigour. Watch for leaf spot in wet conditions (improve drainage and air circulation). The extraordinary chocolate-brown and pink-cream variegated foliage is reliably stunning!

Propagation: Not suitable for home propagation—this cultivar requires specialized propagation techniques. Purchase nursery-grown specimens for guaranteed colour and quality.
