Croton Plant, Codiaeum variegatum (Petra) – Plant

Plant crotons where they will receive direct sunlight for at least six to eight hours a day. They can grow as tall as 6 feet and up to 3 feet wide with enough light. Their green leaves turn to shades of yellow, red and purple throughout the year, showing their brightest colors in the sun in cooler months.

Weather Conditions
Crotons are evergreen plants and will continue to grow throughout winter, when they show off their colors. Crotons grow best at between 60 and 85 degrees Fahrenheit. Lower night or seasonal temperatures will not harm the plants, as they are hardy enough to withstand temperatures as low as 40 F. However, it is wise to cover a bed of crotons or bring potted ones indoors if a frost is expected. The plants can tolerate heat as high as 100 F, but should have some shade in areas that experience severe heat.

Water
Well-drained soil works best for growing crotons outdoors so the soil can dry between waterings. Pots should provide good drainage, as well. Water the plants when the top of the soil is dry. On especially hot days, you may need to water the crotons twice a day. Crotons like humid weather, and misting the plants throughout the hottest days of summer will help the leaves stay bright and healthy.
