Caladium bicolor is a tuberous perennial aroid prized for its striking, paper-thin foliage in intricate patterns of white, pink, red, and green. Native to tropical South America, it naturally inhabits warm, shaded forest understories and seasonally moist sites. The plant grows from a dormant tuber, sending up heart-shaped leaves on slender petioles during the warm, humid months. Indoors and in temperate gardens, it is cultivated primarily for foliage rather than flowers, which are inconspicuous. Caladium has a distinct growth cycle: vigorous leaf production in spring and summer, followed by dormancy as day length shortens and temperatures drop. Success with this species hinges on steady warmth, high humidity, evenly moist but well-drained soil, and protection from direct, harsh sun. It is frequently used in shaded borders, containers, and as a dramatic houseplant accent, especially in bright, indirect light. Because the plant contains calcium oxalates, it is toxic if ingested and can cause irritation, so placement away from pets and children is essential.

How to care for Heart of Jesus
Water
Keep the mix evenly moist during active growth: water thoroughly when the top 2â3 cm (about 1 inch) of soil feels dry, then drain excess. Use a wellâaerated medium and a pot with ample drainage to prevent waterlogging, which quickly rots tubers. Use roomâtemperature water and avoid leaving water pooled in saucers. As days shorten and leaves yellow, reduce frequency sharply; during full dormancy, keep tubers just barely moist or store dry, resuming regular watering only after new sprouts appear.
Light
Give bright, indirect light indoorsâan east window or a shaded south/west exposure with sheer curtains is ideal. Outdoors, dappled shade or morning sun with afternoon shade preserves color and prevents scorch; 30â50% shade cloth works well. Too much direct sun bleaches and burns leaves, while too little light dulls variegation and reduces vigor. Aim for strong, filtered light to maximize color without stressing the thin foliage.
Nutrients
Feed during active growth only. At planting, mix a slowârelease, balanced fertilizer (e.g., 12â12â12 or 14â14â14) into the medium, or topâdress lightly. Supplement every 2â3 weeks with a dilute liquid fertilizer at 1/4â1/2 strength. Favor balanced or slightly higherâpotassium formulas to support leaf color and tuber health; avoid excessive nitrogen, which can dull variegation and cause floppy growth. Flush the pot monthly to prevent salt buildup. Discontinue feeding as leaves yellow and the plant enters dormancy.
Temperature
Warmth is essential. Aim for 21â29°C (70â85°F) by day and keep nights above 18°C (65°F). Avoid temperatures below 13°C (55°F), which can cause collapse and tuber damage. Provide steady warmth at the root zone to initiate sprouting in spring. During dormancy, store tubers dry or slightly moist at 16â21°C (60â70°F). Protect from drafts and sudden swings, and do not move plants outside until nights reliably exceed 16°C (60°F).
