Codiaeum variegatum (Croton) ‘Mrs. Iceton’

Cultivation history and natural range of Codiaeum variegatum (Croton) ‘Mrs. Iceton’

'Mrs. Iceton' was already being traded internationally by 1901, when plants from James H. Veitch & Sons in London reached the United States.

Codiaeum variegatum occurs naturally from Malesia to the south-western Pacific. 'Mrs. Iceton' has been grown for more than a century.

Codiaeum variegatum (Croton) 'Mrs. Iceton' care

• Light for colour: Bright filtered light helps the lime-green new leaves develop pink, cream, yellow and red colouring. Keep the plant close to a bright window. Protect the leaves from intense midday sun through glass.
• Humidity: Aim for 60–80% humidity. Keep it away from direct heat and very dry air, with some gentle airflow around the leaves.
• Temperature: Warmth of about 18–35 °C suits ‘Mrs. Iceton’. Keep temperatures above 16 °C and give the plant a sheltered position away from cold draughts.
• Watering: Water once the surface of the potting mix starts to dry. Wet the root ball evenly, then let the container drain before returning it to its decorative outer pot. Collected rainwater at room temperature is useful in hard-water areas.
• Potting mix: Use a light, free-draining, slightly acidic potting mix that holds some moisture between waterings.
• Feeding: Apply a balanced liquid fertiliser during active growth. When growth slows in cooler, darker conditions, water less often and pause feeding until fresh growth resumes.
• Propagation: Young stem cuttings can be rooted during active growth in warm, humid conditions.
• Repotting and shape: Move to a slightly larger pot when the roots are crowded and need more space. Keep the current pot size until the roots are crowded; refresh the mix separately if it has lost structure. Prune long stems when needed so new shoots grow lower down.

Codiaeum variegatum (Croton) 'Mrs. Iceton' issues and solutions

• Leaves fall after a cold draught or room change: A sudden change in temperature or position can make the plant drop leaves. Keep it warm, stable and evenly moist while it settles.
• Hard brown or greenish bumps appear on leaves and stems: Scale insects may be present. Isolate the plant, remove visible scale, then apply a houseplant treatment labelled for scale and repeat it as often as the label says.
• Leaf edges turn crisp and brown: Dry air or uneven watering is the likely cause. Water consistently as the surface begins to dry and increase humidity around the leaves.
• Many leaves turn yellow while the potting mix stays wet: Root rot may be affecting the plant. Unpot it, remove soft dark roots with a clean, disinfected tool, trim to firm healthy tissue, discard the rotten material and repot in fresh free-draining mix. See our root rot guide for recovery steps.
