Pinstripe Calathea

How to care for Pinstripe Calathea

Light

Goeppertia ornata thrives in bright, indirect light, mimicking the dappled conditions of a tropical forest understorey. A position a metre or two back from an east- or north-facing window is ideal in the UK. Direct sunlight will scorch the leaves and bleach the distinctive pinstripes, while very low light causes slow, leggy growth and dulled colouration. Sheer-curtained south- or west-facing windowsills can also work provided the plant is kept well away from the glass.

Watering

Watering correctly is the most critical aspect of caring for this species. The compost should remain evenly moist during the growing season (spring to early autumn), but should never sit in standing water, which rapidly causes root rot. Allow only the very surface of the compost to dry between waterings. The plant is notably sensitive to fluoride, chlorine, and dissolved minerals, so rainwater, distilled water, or tap water left to stand for 24 hours is strongly recommended. Reduce watering frequency in autumn and winter without allowing the rootball to dry out entirely.

Soil and potting

A well-draining yet moisture-retentive compost is essential. A peat-free mix of two parts houseplant or multi-purpose compost, one part perlite, and one part coir or fine bark works well. This combination retains enough moisture to prevent stress while ensuring sufficient aeration around the roots to prevent waterlogging. Avoid heavy or compacted soils, which impede drainage and encourage root rot.

Feeding

Feed with a balanced, water-soluble liquid fertiliser at half the recommended strength once a month during the active growing season from April to September. Over-fertilising can cause fertiliser burn and tip damage. Do not feed during autumn and winter when the plant's growth naturally slows. Flush the pot through with plain water every two to three months to prevent salt accumulation in the compost.

Humidity and temperature

This species demands high ambient humidity, ideally between 60% and 80%. In typical UK homes, especially in winter when central heating is running, humidity can drop to 30-40%, which causes leaf edges and tips to turn brown and crisp. Grouping plants together, placing the pot on a pebble tray filled with water (ensuring the pot sits above the water line), or using a room humidifier are the most reliable solutions. Regular misting offers only brief relief but can be used as a supplement. The ideal temperature range is 18-27°C; the plant should not be exposed to temperatures below 15°C or to cold draughts from windows, doors, or air-conditioning units.

Repotting

Repot every one to two years in spring, moving up only one pot size at a time (typically increasing the diameter by 2-3 cm). Goeppertia ornata dislikes being overly pot-bound but is also sensitive to excessive root disturbance, so handle the rootball gently. Choose a pot with adequate drainage holes. Terracotta pots can assist with preventing waterlogging but dry out more quickly, so monitor watering accordingly.

Pruning

Pruning requirements are minimal. Remove any yellowed, damaged, or dead leaves at the base using clean, sharp scissors or a blade to maintain the plant's appearance and reduce the risk of fungal disease. Do not cut back healthy foliage, as this will not encourage bushier growth and may stress the plant. Old flower stalks, if they appear, can be removed once the small, inconspicuous flowers have faded.

Common problems

How to propagate

Division

Division at repotting time is the most reliable method. When removing the plant from its pot in spring, carefully separate the rhizome clumps by hand or with a clean, sharp knife, ensuring each division has several healthy stems and an intact section of roots. Pot each division individually into moist, well-draining compost and place in a warm, humid spot to recover, avoiding direct light until new growth appears.

Stem cutting with node

Take a cutting with at least one node and one leaf, ideally in spring or early summer. Place the cutting in water or moist perlite in a warm, humid environment with bright indirect light. Rooting is slower and less reliable than division, and success rates are variable; maintaining high humidity around the cutting by using a clear plastic bag or propagator lid improves outcomes.

Where Pinstripe Calathea comes from

Native to Colombia, Venezuela.

Story and origins

The genus name Goeppertia honours Johann Heinrich Robert Goeppert (1800-1884), a German botanist and palaeobotanist who made significant contributions to the study of fossil plants. The species epithet ornata comes from the Latin word 'ornatus', meaning adorned or decorated, a direct reference to the plant's ornamental leaf markings. The older genus name Calathea, under which this species was long classified, derives from the Greek 'kalathos', meaning a basket, possibly alluding to the basket-like arrangement of the plant's bracts around its flowers.

Goeppertia ornata is native to the humid tropical forests of Colombia and Venezuela, where it grows as a terrestrial plant in the shaded understorey. It was formally described for European botany in the mid-nineteenth century during a period of intense interest in tropical ornamental plants, and its dramatic foliage made it a coveted subject for Victorian plant collectors and heated glasshouses. The broader genus Calathea has cultural significance in parts of South America, where related species have been used to weave baskets and wrap food. The species entered mainstream houseplant cultivation during the late twentieth century as improved understanding of tropical plant care made it more accessible to home growers, and it remains one of the most recognisable and sought-after foliage houseplants in the UK today.

Varieties to know

Goeppertia ornata 'Sanderiana'

One of the most commonly cultivated forms, featuring bold white to pale pink stripes on dark green leaves; frequently sold simply as Calathea ornata

Goeppertia ornata 'Roseolineata'

Notable for its more vivid pink striping, particularly prominent on younger foliage, which may fade to cream or white as leaves mature

Goeppertia ornata 'Beauty Star'

A compact cultivar with finer, more numerous stripes and slightly narrower leaves; commonly found in the UK houseplant trade

Fun facts

• The leaves of Goeppertia ornata move up at night and lower during the day, a process called nyctinasty, driven by changes in water pressure within specialised cells at the base of the leaf stalk called pulvini.
• The species was originally described in 1847 by Belgian botanist Louis Benoit Van Houtte and was long classified under the genus Calathea; molecular studies published in 2012 led to its reclassification into Goeppertia, though the old name Calathea ornata remains in widespread horticultural use.
• The striking pink pinstripes on young leaves are actually more vivid in juvenile foliage and tend to shift to white or cream as the leaf matures, meaning the same plant can display two distinct colourings simultaneously.
• Goeppertia ornata can grow up to 90 cm tall and wide in optimal conditions, making it one of the larger members of the genus commonly kept as a houseplant.
• Members of the Marantaceae family are sometimes called prayer plants because of their nyctinastic leaf movements, a trait they share with the closely related genera Maranta, Ctenanthe, and Stromanthe.
