About Caladium
Caladium bicolor, commonly known as 'Heart of Jesus', is a tropical tuberous plant from the Araceae family, renowned for its large, showy leaves with vibrant patterns of red, pink, white, and green. Its heart-shaped foliage makes it a spectacular focal point, ideal for adding an exotic splash of color to well-lit interiors or shaded gardens in warm climates.

Care tips
It requires bright, indirect light; direct sunlight can scorch its delicate leaves. Keep the substrate consistently moist during its active growing period (spring-summer), avoiding waterlogging, and reduce watering when leaves start to die back in autumn as it enters dormancy. It prefers a rich in organic matter, well-draining, and slightly acidic substrate. A common mistake is exposing it to low temperatures, which can lead to tuber rot or prevent sprouting.
