Caladium
- Growth: Leaves emerge from an underground tuber and many varieties rest seasonally.
- Light: Bright filtered daylight keeps delicate foliage away from strong midday sun.
- Watering: Keep the mix lightly moist while leafy; reduce water substantially during dormancy.
- Pet safety: Leaves and tubers contain irritating calcium oxalate crystals.
Caladium comes from tropical American habitats where plants grow from underground tubers. These store reserves through a resting period, allowing new leaves to emerge when warmth and moisture return.
Caladium plants
Caladium ‘White Queen’ has pale leaves marked with red veins, and ‘Rosebud’ carries warm pink centres. ‘Spring Fling’ adds strong pink colour on broad leaves, while other cultivars produce narrower, strap-like shapes. Their leaf width and mature height determine how much room they occupy in a planter.
Most Caladiums grow in warmth and bright filtered daylight. Water during active leaf growth as the surface begins to dry, keeping some moisture around the tuber without waterlogging the pot.
Many Caladiums lose their foliage when growth slows and rest in the tuber until conditions improve. During this leafless period they need far less water. Fresh shoots signal the return of active growth.

Frequently Asked Questions About Caladium
Are Caladiums grown for flowers or foliage?
Caladiums are mainly grown for their striking leaves, which can be pink, red, white or green. Small flowers may appear, but the seasonal foliage is usually their main attraction.
Do Caladiums want bright light or shade indoors?
Warm, bright filtered daylight allows Caladium leaves to develop their colour. Strong direct sunlight can scorch thin foliage, particularly on plants accustomed to shade.
Do Caladiums go dormant indoors?
Many Caladiums naturally lose their leaves during a resting period, especially as warmth and daylight decrease. The tuber remains beneath the surface and can produce fresh shoots when growth resumes.
How should I water Caladium during growth and dormancy?
Water while leaves are actively growing, keeping some moisture around the tuber and allowing excess to drain. After the foliage naturally dies back, keep the resting tuber nearly dry and resume watering gradually when shoots emerge.
Are Caladiums safe around pets?
No. Caladium are toxic to cats and dogs and can cause painful mouth irritation if chewed.
