What Is Caladium?
Caladium, commonly known in Brazil as “Tinhorão” or “Heart of Jesus”, is a tropical ornamental plant native to South America, particularly found in the Brazilian Amazon. It is best known for its large, heart-shaped leaves with vibrant colors and variegated patterns, making it a favorite choice for home gardens and interior decoration.
Main Characteristics of Caladium
This plant stands out for its spectacular foliage, which may include shades of green, red, pink, and white, often with striking vein patterns. Each leaf can look different from the next, giving each plant a unique and dynamic appearance.
Key features:

- Rarely flowers: the appeal lies in the foliage
How to Grow Caladium at Home
To keep your Caladium lush and beautiful, it’s important to provide the proper growing conditions. Here’s how:
1. Light
Caladium thrives in indirect light or partial shade. Direct sunlight may burn or fade the vibrant leaves, so it’s ideal for covered patios, indoor spaces with natural light, or under trees in shaded gardens.
2. Watering
Keep the soil consistently moist but never soggy. Water two to three times a week, adjusting according to the season. During winter dormancy, reduce watering.
Pro tip: Avoid standing water in saucers to prevent root rot.
3. Soil
Use light, well-draining soil rich in organic matter. A recommended mix:
- 1 part potting soil
- 1 part coarse sand
- 1 part compost or worm castings
4. Fertilizing
Feed your plant every 15 days during spring and summer using nitrogen-rich liquid fertilizers, which encourage healthy and colorful leaf growth.
5. Temperature
Caladium prefers warm climates between 20°C and 30°C (68°F to 86°F). It’s sensitive to cold and cannot tolerate frost or temperatures below 10°C (50°F).
Propagation of Caladium
The plant propagates through tuber division. During dormancy (usually in winter), you can dig up the tubers, separate them, and replant each one in a new pot. This allows you to multiply your collection easily.
Is Caladium Toxic?
Yes, Caladium is toxic to pets and humans if ingested. Its leaves and tubers contain calcium oxalate crystals, which may cause:
- Irritation of the mouth and throat
- Nausea or vomiting
- Breathing difficulty in severe cases
Keep the plant away from pets and children to avoid accidents.
