Caladium 'Candidum' – Bright White Foliage for Shaded Spaces


Caladium 'Candidum' is a classic ornamental hybrid prized for its large, heart-shaped white leaves with bold green veins. Originally developed from tropical aroid species like Caladium bicolor, this cultivar offers elegant contrast in indoor settings or shaded patios. Its luminous foliage brightens low-light corners and adds refined texture to any plant collection.


What Makes Caladium 'Candidum' Special



 
Iconic Leaf Design: White leaf blades with clearly defined green venation form a graphic, high-contrast pattern.
 
Elegant Growth Habit: Tuberous perennial that reaches 60–70 cm in height during active growth.
 
Seasonal Beauty: Active in spring and summer, followed by natural dormancy in cooler months.


Natural Habitat of Caladium Ancestors


Caladium species originate from the tropical lowland rainforests of northern South America, particularly Brazil, Colombia, Venezuela, and the Guianas. They grow under forest canopies in warm, humid, and well-drained soils. Cultivars like 'Candidum' are bred from these wild types for decorative use and do not occur naturally in the wild.


How to Care for Caladium 'Candidum'



 
Light: Prefers bright, filtered light. Avoid direct sun, which can bleach or scorch the leaves.
 
Watering: Keep soil lightly moist during active growth. Let the top 2–3 cm dry out slightly between waterings.
 
Humidity: Requires 60–80% humidity. Use a humidifier or group with other plants to raise moisture levels.
 
Temperature: Thrives between 18–27°C. Growth slows below 16°C; avoid exposure to cold drafts.
 
Soil: Use a loose, well-draining mix (e.g., coconut coir, fine bark, and perlite). Avoid compact or peat-heavy mixes.
 
Feeding: Fertilize every 4–6 weeks during the growing season with a balanced liquid fertilizer.
 
Propagation: Divide tubers in spring, ensuring each section has at least one visible growth eye.
 
Repotting: Replant stored tubers in fresh mix once active growth resumes in spring.


Dormancy and Reactivation


Caladium 'Candidum' enters dormancy in late autumn or when temperatures drop. Allow leaves to die back naturally. Remove tubers, clean and dry them, then store in breathable material (e.g., paper bag or sawdust) at 15–18°C in a dark, dry place. To reactivate in spring, soak tubers in lukewarm water for a few hours before potting in fresh substrate.


Common Problems and Solutions



 
Yellow Leaves: Often caused by excess moisture. Let soil dry slightly before watering again.
 
Brown Leaf Edges: Usually linked to low humidity or mineral buildup. Raise humidity or flush soil periodically.
 
Pests: Vulnerable to spider mites, aphids, and mealybugs. Use neem oil or insecticidal soap.
 
Root Rot: Caused by waterlogged soil. Ensure excellent drainage and remove affected tubers promptly.


Etymology of Caladium 'Candidum'


The genus name Caladium comes from the Malay word kaladi, referring to tuberous aroids. The species name bicolor means "two-colored" in Latin and originally described the contrast in wild plants. The cultivar name 'Candidum' is Latin for "bright white", referencing the plant’s signature leaf color.
