Overview
Petra Croton is a tropical evergreen shrub with broad leathery leaves marked green, yellow, orange, and red. Strong light intensifies color. Protected Central Florida plants often reach 4 to 8 feet tall and wide.
Mature Size and Habit
It develops an upright, branching form with foliage near the base when light is adequate. Leave room for the colorful canopy instead of compressing it behind larger shrubs.
Best Landscape Uses
Use it as a bold foundation accent, tropical border, poolside feature, or large container specimen. Repeated groups create stronger color and are easier to protect from cold.
Sunlight
Bright light to partial sun produces rich color. Established plants adapt to full sun with irrigation. Deep shade turns leaves greener, while abrupt intense exposure can scorch shade-grown foliage.
Soil, Drainage, and Irrigation
Plant in fertile, well-drained soil and water evenly during establishment. Mature plants tolerate brief dryness but drop leaves in severe drought. Avoid constant wetness and excessive fertilizer.
Best Planting Season for Tampa and Central Florida
Plant from late March through early fall after cold risk declines. Warm soil speeds establishment. Avoid installing tender crotons shortly before winter in exposed locations.
Pruning and Maintenance
Pinch or selectively prune during warm weather to encourage branching. Wait for spring growth before removing freeze-damaged wood. Watch for scale, mealybugs, mites, and thrips.
Wildlife Value
Flowers are small and food value for Florida wildlife is limited. Dense foliage gives minor shelter. Pair croton with nectar and berry-producing native plants for stronger habitat value.
Cold and Heat Sensitivity
Petra thrives in heat and humidity but is frost-sensitive. Near-freezing weather can cause leaf drop and stem injury. A warm wall or courtyard offers useful protection.
Safety, Roots, and Placement Warnings
Milky sap can irritate skin and eyes, and plant parts are toxic if eaten by people or pets. Wear gloves when pruning. Roots are not considered aggressive.
Invasive Concerns
Codiaeum variegatum is nonnative. The current UF/IFAS assessment does not list it as a problem species in Central Florida. Keep plants in maintained beds and remove volunteers.
