Garden croton is an evergreen tropical shrub grown for its brightly coloured, leathery leaves. It needs warmth, bright light to show its colours, and protection from cold.

Family
Euphorbiaceae (Spurge family)
Grows as
Tree, Shrub
Light
Full sun, Bright indirect
Water
Water when the top few centimetres of soil dry out; keep evenly moist in the growing season and water less in winter.
Soil
Well-drained, peat-based potting mix or loamy garden soil.
Temperature
18–30 °C; protect below 10 °C, as cold causes leaf loss.
How easy
Moderate
Safety
Mildly toxic: All parts exude a milky, caustic sap that irritates skin, eyes and mucous membranes; avoid contact with the sap and wear gloves when handling.
Native range
Malesia to SW. Pacific
Climate
wet tropical

About

Codiaeum variegatum, commonly known as croton or variegated croton amongst many other names, is a species of plant in the Euphorbiaceae family. Initially described by Carl Linnaeus in 1753, its native range is from Java east to Fiji, and from the Philippines south to Queensland, Australia. It is widely cultivated and has been introduced to many other countries.

How to grow it

In tropical climates, crotons make attractive hedges and potted patio specimens, valued for their striking foliage. They only survive outdoors where temperatures do not normally drop below 10 to 13 °C (50 to 55 °F) in winter; colder temperatures can cause leaf loss. In colder climates, the plants are grown in greenhouses or as house plants. The cultivated garden crotons are usually smaller than the wild plant, rarely over 1.8 m (5.9 ft) tall, and occur in a wide diversity of leaf shapes and colours. They are sometimes grouped under the name Codiaeum variegatum var. pictum (Lodd.) Müll. Arg., though this is not botanically distinct from the species and usually treated as a synonym of it.

Safety

As with the majority of the spurges, when broken or cut, every part of C. variegatum will "bleed" and drip a milky, caustic sap, eventually drying into a latex-like consistency. Care must be taken to avoid touching this latex, such as only handling the plant while wearing sufficiently protective gloves, as well as eye goggles or sunglasses. Generally, small, inadvertent drops of the sap on one's hands or skin will cause no ill effect in the majority of the population, provided it is promptly washed off using soapy, warm water—this may even be followed with the use of a hand sanitizer or even a mildly diluted isopropyl alcohol. However, direct contact between the sap of Euphorbiaceae and the eyes, ears, nose, mouth, genitals, or any open wound, is strongly discouraged and may result in unknown side effects.

Where it grows

The natural range of the variegated croton is Malesia (Borneo, Java, the Lesser Sunda Islands, Maluku, the Philippines, Sulawesi), Papuasia (Bismarck Archipelago, New Guinea, the Solomon Islands), Queensland, and the Pacific islands of Fiji, the Santa Cruz Islands and Vanuatu. It is now found much further afield due to it being widely cultivated.
