Tuber Dormancy & Sprouting
2-4 weeksCaladium tubers are dormant during cool months. When temperatures warm (65-70°F+), eyes begin to sprout and small shoots emerge from the tuber.
Start tubers indoors in spring or wait until soil temperatures reach 70°F. Provide warmth and light humidity. Do not overwater at this stage.
Seedling & Leaf Emergence
3-4 weeksYoung shoots develop their first leaves, which are typically smaller and lighter in color than mature foliage. The characteristic heart shape begins to appear.
Maintain consistent moisture and warmth (70-80°F). Provide bright, indirect light. High humidity promotes healthy leaf development.
Vegetative Growth & Foliage Development
6-10 weeksMature leaves unfold with full color expression—deep red veining and centers with pale margins become prominent. Plant establishes several leaves and bushy growth.
Water regularly, allowing soil surface to dry slightly between waterings. Maintain humidity above 60%. Feed with balanced, diluted fertilizer every 2-3 weeks during growing season.
Peak Ornamental Display
8-12 weeks (maintains through growing season)Plant reaches full size with multiple large, vibrant heart-shaped leaves displaying rich red veining and contrasting pale centers. May produce insignificant flowers (typical of caladiums).
Continue regular watering and fertilizing. Pinch off flowers if they appear to encourage foliage production. Monitor for pests in warm, humid conditions.
Dormancy & Tuber Rest
3-5 months (winter dormancy)As temperatures cool in fall and winter, leaves yellow and wither. The plant enters dormancy to conserve energy in the tuber.
Reduce watering gradually as leaves fade. Allow soil to dry out. Stop fertilizing. Store tubers in cool (50-60°F), dry location if digging up, or allow to rest in dormant soil indoors.

Harvest Tips
Caladiums are grown for foliage, not harvested in the traditional sense. To maintain appearance, pinch off flower spikes as they appear. In fall, allow foliage to die back naturally or cut stems near soil level. Dig up and store tubers in a cool, dry place for winter dormancy, or leave in soil if keeping plant indoors year-round.
Fun Facts
- 🌱 Caladium Carolyn Whorton is named after a hybrid cultivar selection; caladiums are among the few plants where the decorative leaves are more valuable than flowers, as they produce tiny, inconspicuous inflorescences.
- 🌱 Caladiums are native to South America (Colombia, Venezuela, and Brazil) and have been cultivated for centuries; the name 'Caladium' comes from the Tupi word 'kalam,' reflecting the plant's deep cultural significance in tropical regions.
- 🌱 The striking leaf patterns in Caladium Carolyn Whorton develop more vibrant red coloration when the plant receives brighter indirect light—the red pigments (anthocyanins) act as a natural sunscreen to protect chlorophyll in higher-light conditions.
