Codiaeum variegatum (Croton) 'Petra'

Codiaeum variegatum 'Petra' is a classic broad-leaved croton with pointed oval leaves and bold yellow, orange, pink and red markings along the main veins. It forms an upright, woody shrub with glossy foliage and a dense canopy when grown warm and bright.

Firm leaves held along sturdy stems give the plant an upright outline. As new foliage matures, different colour stages build across the crown in bright indoor spaces.

Standout details of Codiaeum variegatum 'Petra'

• Broad, pointed oval leaves with strong coloured venation
• Upright evergreen shrub habit indoors
• Glossy, leathery foliage on woody stems
• Layered canopy as leaves mature through colour stages
• Widely grown croton cultivar for bright indoor containers

Codiaeum variegatum 'Petra' venation and growth habit

Codiaeum variegatum is a wet-tropical shrub or small tree from Malesia to the southwest Pacific, belonging to Euphorbiaceae. The species has produced many cultivated foliage forms with different leaf shapes and colour patterns. 'Petra' has broad pointed leaves with colour following the main veins.

Indoors, Codiaeum variegatum 'Petra' develops as a manageable container shrub. The leaves are alternate, thick and glossy, and older stems gradually become woodier. Flowering is occasional in warm, bright conditions, but the small flowers are secondary to the foliage.

Codiaeum variegatum 'Petra' care

• Light: Choose a very bright filtered position. Acclimated plants can take gentle direct sun; harsh midday summer sun behind glass can scorch foliage.
• Watering: Water when the top 2–3 cm of substrate start to dry. Keep moisture even during active growth and reduce slightly in winter.
• Substrate: Use a fertile, well-drained potting mix with bark, organic matter and mineral drainage. Broad-leaved crotons need both moisture and root aeration.
• Temperature: Keep above 15 °C and protect from draughts. Stable warmth between 18 °C and 28 °C keeps new leaves forming steadily.
• Humidity: Moderate to high humidity reduces dry edges during new leaf expansion.
• Feeding: Feed at low strength during the main growing season. Reduce feeding in low light or after repotting.
• Cleaning: Wipe dusty leaves gently with water. Clean foliage makes scale and spider mite checks easier.
• Pruning: Prune in spring to shape tall stems and encourage branching. Wear gloves, as sap can irritate skin and stain fabric.
• Repotting: Repot once roots fill the container, using a pot only slightly larger. Fresh mix matters more than excess pot volume.
• Propagation: Propagate through warm stem cuttings or air layering to keep 'Petra' true to type.

Codiaeum variegatum 'Petra' leaf and root warnings

• Lower leaf drop: Check cold draughts, recent relocation, dry substrate and wet roots. Correct the main stress point and avoid repeated moves.
• Brown tips or margins: Review humidity, watering consistency and fertiliser salt build-up. Flush the pot and return to steadier watering.
• Scale insects: Look for small raised bumps along stems and veins. Remove visible insects and repeat treatment through the next growth cycle.
• Spider mite stippling: Pale dots and fine webbing point to mites, especially in dry heated rooms. Rinse leaves and isolate the plant early.
