Tradescantia Nanouk

How to care for Tradescantia Nanouk

Light

Tradescantia Nanouk requires bright, indirect light to maintain its vivid pink and white variegation. Direct midday sun can scorch the leaves, but insufficient light will cause the foliage to revert to a greener, less colourful appearance. An east- or west-facing windowsill is generally ideal; a south-facing position is acceptable if the plant is set back from the glass or filtered with a sheer curtain.

Watering

Water thoroughly when the top 2 cm of compost have dried out, then allow any excess to drain freely from the pot. Overwatering is the most common error and leads to root rot; the roots should never sit in standing water. Reduce watering frequency in autumn and winter when growth slows, but do not allow the compost to dry out completely.

Soil and potting

Use a free-draining, peat-free multipurpose compost mixed with around 20-30% perlite or coarse grit to improve drainage and aeration. A slightly acidic to neutral pH of 6.0-7.0 is suitable. Heavy or water-retentive composts should be avoided as they increase the risk of root rot.

Feeding

Apply a balanced liquid fertiliser at half strength once a month during the active growing season from spring through to early autumn. No feeding is required during winter when the plant is not actively growing. Over-fertilising can cause excess foliage growth at the expense of the plant's characteristic colour.

Humidity and temperature

Nanouk tolerates average household humidity of around 40-60% and does not require the high humidity demanded by many tropical houseplants. Temperatures between 15 and 24°C are preferred; the plant will suffer below 10°C and should not be exposed to frost. Keep it away from cold draughts, radiators, and air-conditioning vents, which can cause leaf browning at the tips.

Repotting

Repot every one to two years in spring when the roots begin to emerge from the drainage holes or the plant appears pot-bound. Move up only one pot size at a time, typically to a pot 2-3 cm wider in diameter, using fresh well-draining compost. Terracotta pots are beneficial as they allow excess moisture to evaporate through the walls.

Pruning

Regular pinching out of the growing tips encourages a bushy, compact habit and prevents the plant from becoming straggly. Leggy stems can be cut back hard to a node in spring, and the cuttings used for propagation. Removing dead or faded leaves promptly keeps the plant tidy and reduces the risk of fungal issues.

Common problems

How to propagate

Stem cuttings in water

Cut a healthy stem of 8-12 cm just below a leaf node and remove the lower leaves. Place the cutting in a glass of water in a bright, warm spot and roots will typically appear within two to three weeks, after which it can be potted into compost.

Stem cuttings in compost

Prepare cuttings as above and insert them directly into a small pot of moist, well-draining compost. Keep the compost lightly moist and place in bright indirect light; rooting usually occurs within three to four weeks.

Division

When repotting, the root ball can be gently divided into two or more sections, each with healthy stems and roots attached. Pot each division individually into fresh compost and water in gently.

Where Tradescantia Nanouk comes from

Native to southern Brazil, Argentina, Uruguay.

Story and origins

The genus name Tradescantia honours John Tradescant the Elder (c. 1570-1638) and his son John Tradescant the Younger (1608-1662), both English botanists and gardeners who served as royal gardeners to King Charles I and were among the first collectors to introduce North American plants to Britain. The species epithet albiflora is derived from the Latin alba (white) and flos or flora (flower), referring to the white flowers typical of this species. The cultivar name 'Nanouk' is a proprietary trade name given by the breeder Terra Nigra; it does not have a botanical Latin meaning but is thought to evoke a sense of the exotic and compact nature of the plant.

Tradescantia albiflora is native to parts of South America, particularly southern Brazil, Argentina, and Uruguay, where it grows as a ground-cover plant in moist, shaded environments. The broader Tradescantia genus was introduced to European horticulture in the early seventeenth century through the plant-hunting expeditions of the Tradescant family, who collected specimens from the eastern coast of North America. The species albiflora and its various forms became popular trailing houseplants throughout the twentieth century due to their vigour and ease of cultivation. The 'Nanouk' cultivar represents a modern horticultural development, bred in the Netherlands in 2012 specifically to produce a more compact, more colourful, and more commercially attractive form than existing cultivars. It was patented and launched commercially around 2017 and rapidly became one of the most popular houseplants sold across Europe and North America.

Varieties to know

Tradescantia albiflora 'Nanouk'

The cultivar itself is the subject of this entry; it is distinct from the straight species by its broader, more intensely coloured variegated leaves and more compact growth habit.

Tradescantia fluminensis 'Tricolor'

A closely related trailing spiderwort with white and pink variegation but a less compact habit than Nanouk.

Tradescantia zebrina

Features bold silver and green stripes with a purple underside; a popular relative with a similarly easy care regime.

Tradescantia pallida 'Purpurea'

Known as purple heart or purple spiderwort; entirely deep purple foliage with no variegation, often used outdoors as ground cover in mild climates.

Fun facts

• Tradescantia Nanouk was bred specifically through controlled cross-pollination by the Dutch company Terra Nigra and was granted a US plant patent in 2017 (US Plant Patent PP29711).
• The small, three-petalled flowers of Tradescantia Nanouk are white to pale pink and are perfectly edible, though the plant is grown almost exclusively for its foliage.
• Despite its tropical appearance, Nanouk is notably more tolerant of lower light conditions than many other variegated houseplants, making it more adaptable to average homes.
• The cells in Tradescantia staminal hairs were among the first plant cells in which cytoplasmic streaming (cyclosis) was observed and studied under microscopy, making the genus historically significant in plant biology.
• Tradescantia albiflora can root at virtually any node that comes into contact with moist soil, giving the species a vigorous and sometimes invasive habit in warm outdoor climates.
