Croton
Codiaeum variegatum · Euphorbiaceae
Hardly any foliage plant brings as much colour into a room as the croton: yellow, orange, red and green often marble across one and the same leaf. In return it demands a little more attention than a rubber plant — above all a consistently bright, warm spot without draughts. We buy our crotons in mature, fully coloured quality at the Veiling Rhein-Maas.
- Light
- Very bright with gentle sun; the more light, the more intense the leaf colouring.
- Watering
- Evenly, lightly moist with soft, room-temperature water; neither let it dry out nor allow waterlogging.

- Codiaeum variegatum
The variety range is enormous: Petra with broad, colourfully veined leaves is the trade classic, Mammi curls narrow and fiery, Excellent carries lobed leaves reminiscent of oak foliage, and Zanzibar with its almost grass-like leaves looks nearly like an ornamental grass. In all of them, colour intensity depends directly on light.
This is exactly where the most common care mistake lies: if the croton stands too dark, the leaves revert to green and new growth stays pale. A spot right by an east or west window is ideal; gentle morning and evening sun boosts the colouring. Only harsh midday sun behind south-facing glass can scorch.
The second sticking point is loyalty to its spot: the croton likes to answer relocation, draughts and cold feet with leaf drop. Temperatures should not fall below 17 degrees Celsius year-round, and the pot should not sit on a cold stone floor. Give it a fixed, warm place and it rewards you with dense foliage.
As a member of the spurge family, the croton carries a white milky sap in all its parts that irritates skin and mucous membranes. Wear gloves when pruning and briefly dab the cuts with lukewarm water. For households with cats, dogs or small children it is only suitable out of reach.
Water evenly with room-temperature, soft water: the root ball should stay lightly moist but never stand in water. The croton answers dry heating air with brown leaf edges and an invitation to spider mites — regular misting or a humidifier by the radiator prevents both.
In our floristry work we like using the croton as a warm colour accent in autumn and winter, when the colours disappear outside. Its fireworks show best next to calm greens such as dracaena or schefflera — too many colourful neighbours steal its stage.

- Toxic
All parts of the plant are toxic to cats, dogs and children. The milky spurge sap irritates skin and mucous membranes on contact alone. Keep well out of reach and wear gloves when pruning.
Typical symptoms: After chewing: burning in the mouth, heavy drooling, vomiting and diarrhoea; skin contact with the sap can cause redness and blistering.

Overview: toxic & non-toxic plants for cats, dogs and children
Care
- 01Place very bright and warm (18–24 degrees Celsius); morning and evening sun yes, harsh midday sun no.
- 02Do not move it around and avoid draughts — otherwise the croton drops leaves.
- 03Keep evenly, lightly moist, watering with room-temperature soft water; avoid waterlogging.
- 04Keep humidity high: mist regularly, especially during the heating season.
- 05Wear gloves when cutting — the milky sap irritates skin and mucous membranes.
- 06Feed every two weeks from spring to autumn, monthly in winter.
Frequently asked
- Is the croton toxic to cats and dogs?
- Yes. The croton belongs to the spurge family, and its milky sap irritates mouth, stomach and skin. In cats and dogs, chewing leads to drooling, vomiting and diarrhoea. In pet households keep it strictly out of reach, or better still choose a pet-safe alternative.
- Why is my croton dropping leaves?
- Leaf drop is the croton's typical stress reaction — usually after relocation, draughts, cold temperatures or a dried-out root ball. Give it a fixed, warm, bright spot, water evenly and be patient: it will reshoot from healthy stems.
- Why are my croton's colourful leaves turning green?
- That is almost always a lack of light. The croton only produces its red, orange and yellow pigments in strong light; in shade the green chlorophyll takes over. A spot right by a bright window brings the colour back in new leaves.
- How big does a croton get indoors?
- With good care, Codiaeum variegatum reaches a good one to one and a half metres indoors over the years. In its homeland it grows into a shrub several metres tall. Regular pruning in spring keeps it compact and encourages branching — remember the gloves.
