Croton is an extensive plant genus in the spurge family, Euphorbiaceae. The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to Codiaeum variegatum. These plants are native to the tropical forests of Southeast Asia and the Pacific islands, including regions like Indonesia, Malaysia, and the Pacific islands.
Oakleaf Croton, also known as Codiaeum variegatum ‘Oakleaf’ is named for its leaves, which are tri-lobed, resembling the shape of oak leaves. These leaves can grow quite large, up to several inches in length, and are thick and glossy. The coloration is one of its standout features, with leaves often displaying a mix of green, yellow, red, burgundy, and sometimes even orange. The variegation can appear as splotches, veins, or edges, creating a dramatic and colorful display.
This variety can grow relatively tall, potentially reaching up to 3-6 feet indoors, though it can grow even taller in optimal outdoor conditions. Its growth habit is generally upright but can become bushier with proper pruning. It prefers warm temperatures, ideally between 60-85°F (15-29°C). It’s not frost-tolerant, so it’s best kept indoors in cooler climates or in a protected spot outdoors in warmer climates.
Like other Crotons, the Oakleaf thrives in bright, indirect light. Direct sunlight can enhance the color intensity of its leaves, but too much can lead to leaf burn. Insufficient light will cause the leaves to lose their vibrant colors, reverting to a more solid green.
Oakleaf Croton appreciates high humidity. You can increase humidity by misting the leaves, placing the pot on a tray with pebbles and water, or using a humidifier, especially in dry indoor environments. Also a well-draining potting mix is important when growing this houseplant. A mix designed for tropical plants or a standard potting mix with added perlite or sand for better drainage works well.
Care Tips
- Fertilization: Feed with a balanced, water-soluble fertilizer during the growing season (spring through summer) every 2-4 weeks. Reduce or stop fertilization in the fall and winter.
- Pruning: Pruning can help maintain its shape and encourage bushier growth. It’s also beneficial for removing any damaged or discolored leaves to keep the plant looking its best.
- Toxicity: Like other Crotons, the Oakleaf Croton is toxic if ingested, so it should be kept out of reach of pets and children.
- Pests: Keep an eye out for common pests like spider mites, scale, and mealybugs. Regular inspection and cleaning of leaves can help prevent infestations.
