Codiaeum variegatum ‘Petra’ is one of the most popular and instantly recognisable croton cultivars, renowned for its vivid multicoloured foliage. Native to the tropical regions of Southeast Asia and the Pacific Islands, crotons are part of the Euphorbiaceae family and have been grown for centuries as decorative plants thanks to their flamboyant leaf patterns and rich colours.

‘Petra’ is particularly admired for its bold, leathery leaves, which can be large and elongated with pointed tips. The base colour of the foliage is a glossy dark green, dramatically patterned with veins and margins in shades of bright yellow, fiery orange, and deep red. This kaleidoscope of colours becomes more intense as the plant matures, with older leaves often developing rich burgundy tones.

Its upright, bushy growth habit makes it ideal as a feature plant indoors, where it provides a tropical, almost exotic atmosphere. When well cared for, it can reach between 90–150 cm in height, creating a vibrant focal point in living rooms, conservatories, or offices.

Codiaeum variegatum ‘Petra’ – Care Guide

Light

Requires bright, indirect light to maintain strong variegation and bold colours. An east- or south-facing window with filtered sunlight is ideal. Too little light results in dull, greenish leaves, while too much direct sun can scorch them. Rotate regularly to ensure balanced growth.

Watering

Keep the soil evenly moist but never soggy. Water when the top 2–3 cm of soil feels dry. Reduce watering slightly in winter but do not allow the soil to dry out completely. Use lukewarm water to avoid shocking the roots.

Temperature and Humidity

• Temperature: Prefers 18–26°C. It is sensitive to cold and should not be exposed to temperatures below 15°C. Protect from draughts.

• Humidity: Needs high humidity to thrive. Mist leaves regularly, place on a pebble tray, or group with other tropical plants to maintain adequate moisture in the air.

Soil and Potting

Use a rich, well-draining potting mix. A peat-free houseplant compost mixed with perlite or sand for aeration works well. Repot every 1–2 years in spring to refresh the soil and provide more room for roots.

Feeding

Apply a balanced liquid fertiliser every 2 weeks during the growing season (spring and summer). In autumn, reduce to monthly, and stop feeding entirely in winter.

Pruning and Maintenance

Prune lightly in spring to maintain shape and encourage fuller growth. Remove any faded or damaged leaves at the base. Wipe the leaves with a damp cloth regularly to maintain their sheen and allow for efficient photosynthesis.

Growth and Maturity

Indoors, ‘Petra’ usually grows to around 90–120 cm, but with excellent care can reach up to 150 cm. Its slow but steady growth ensures that its colourful display remains a long-lasting feature in the home.

Common Issues

• Leaf drop: Common if exposed to low humidity, draughts, or sudden environmental changes.

• Colour fading: Caused by insufficient light.

• Pests: May be affected by spider mites, mealybugs, or scale; inspect leaves regularly.

Background and Benefits

Crotons like ‘Petra’ have long been cultivated for their ornamental beauty. In their native tropical landscapes, they are grown as hedges and shrubs, while in cooler climates they are prized houseplants. ‘Petra’ is one of the most enduring and widely grown varieties thanks to its striking, painterly foliage, which instantly transforms any room with a splash of tropical colour.
