Caladium bicolor · also called Angel wings, Elephant ear, Heart of Jesus, Fancy-leaved caladium
⚠ Toxic to pets
Toxic to cats and/or dogs — keep out of reach.
Grown for paper-thin, heart-shaped leaves splashed in pink, red, white, and green, the caladium is a tuberous tropical that puts on a spectacular foliage show in the warm season and then dies back to a dormant tuber.

Toxic to pets
Light
Most caladiums prefer bright, indirect light or dappled shade, which keeps the vivid leaf colors richest; harsh direct sun can scorch the delicate leaves, though some newer 'sun-tolerant' selections take more. In too little light the colors fade and the plant grows weak. Bright but filtered light is the sweet spot indoors.
Water
During active growth keep the soil consistently moist but not soggy, watering when the surface begins to dry — the lush leaves wilt fast if the plant dries out. As leaves naturally yellow and die back at the end of the season, taper off water and let the tuber go dry for its dormant rest. Overwatering a dormant tuber rots it.
Soil & potting
Use a rich, organic, well-draining potting mix; caladiums grow from tubers that rot in heavy, waterlogged soil. Plant tubers knobby-side up. Provide a pot with good drainage and refresh the mix when replanting dormant tubers each season.
Environment — humidity, temperature, placement
Caladiums are true heat-lovers and the most important rule is warmth: they sulk, fail to sprout, or rot in cool soil, wanting consistently warm temperatures (roughly above 65-70F / 18-21C) and high humidity. They naturally go dormant when temperatures drop, dying back to the tuber, which can be lifted and stored warm and dry over winter, then restarted in warmth. Cold drafts and chilly windowsills are their enemy.
Propagation
Propagate by dividing the dormant tubers: cut a healthy tuber into sections, each with at least one 'eye' (growth bud), let the cuts dry briefly to callus, and pot them in warm, lightly moist mix. They can also be grown from the small offset tubers that form around the parent. Warmth is essential for sprouting.
Toxicity detail
Toxic to cats and dogs. The ASPCA lists Caladium as toxic due to insoluble calcium oxalate crystals shared across the arum family. Chewing causes intense oral and esophageal irritation and burning, drooling, vomiting, and difficulty swallowing; severe oral swelling is possible. Keep the plant and any stored tubers away from pets and contact a veterinarian if ingested. Source: ASPCA Animal Poison Control toxic-plant database.
Origin & history
Caladium bicolor hails from the tropical Americas and was brought into cultivation in the 18th and 19th centuries, with intensive breeding — much of it historically centered in Lake Placid, Florida, which calls itself the 'Caladium Capital of the World' — producing the dazzling array of leaf patterns grown today. Indigenous Amazonian peoples knew the plants long before European horticulture, and the genus name traces to a local South American name for the plants.
Growth stages
How this plant changes through its life — each stage often has its own care, diet and space needs.

Seed
Most plants begin as a seed (or spore in ferns) — a dormant package holding the embryo and a food reserve within a protective coat. Given moisture, warmth, and sometimes light, the seed breaks dormancy and germinates.
Photo coming soon
Seedling
The seedling emerges with a root and its first leaves (cotyledons), then true leaves. It is tender and shallow-rooted, dependent on steady moisture and light as it establishes the beginnings of stem and root systems.

Vegetative growth
In the vegetative phase the plant focuses on growing roots, stems, and foliage, building the size and structure it needs before flowering. This is the main period of leafing out and, for many houseplants, the stage at which they are grown and propagated.
Mature / Flowering
A mature plant reaches its full habit and, when conditions and age allow, flowers and sets seed (or, for foliage plants, simply attains its full adult size and form). This is the stage shown in most reference photos.
Problems & solutions
Each problem lists a proven fix (horticulture / extension-backed) and, where useful, an anecdotal remedy from the grower community — clearly labeled so you can judge for yourself.
Tuber fails to sprout / rots before growth
moderate
Symptoms:A planted tuber sits for weeks without sprouting, or turns soft and mushy in the soil.
Likely cause:Cold soil and/or overwatering. Caladium tubers need genuine warmth to break dormancy and rot readily in cool, wet mix before they ever sprout.
✓ Proven fix
Start tubers only in warm conditions (consistently warm soil), keep the mix barely moist until shoots appear, and increase watering only once leaves are growing. Bottom heat or simply waiting for warm weather greatly improves sprouting.
◇ Anecdotal remedy — grower lore, unverified
Many growers pre-sprout tubers in a warm spot indoors (such as on top of the refrigerator) before potting them, crediting the steady warmth for faster, more reliable shoots.
Leaves die back in autumn (dormancy)
mild
Symptoms:Leaves yellow, flop, and die down until nothing is left above the soil, usually as days shorten and cool.
Likely cause:Natural seasonal dormancy — caladiums are deciduous tuberous plants that rest each year, not a disease.
✓ Proven fix
Reduce and then stop watering as the foliage fades, and either leave the tuber dry in its pot in a warm place or lift, dry, and store it warm over winter, restarting it in warmth in spring. Do not keep a leafless tuber wet.
◇ Anecdotal remedy — grower lore, unverified
Cold-climate gardeners often store cleaned tubers in dry peat or vermiculite in a box, much as one would store dahlia tubers, and report good survival year to year.
Scorched or faded leaves
mild
Symptoms:Leaf colors look washed out, or thin patches turn brown and papery.
Likely cause:Too much direct sun bleaching and burning the delicate leaves, or conversely too little light dulling the colors. Low humidity also crisps the thin foliage.
✓ Proven fix
Give bright but filtered/indirect light (or dappled shade outdoors), avoid harsh midday sun on standard varieties, and raise humidity. Remove badly scorched leaves; new growth will come in cleaner under better light.
◇ Anecdotal remedy — grower lore, unverified
Growers often note that the so-called 'sun-tolerant' strains genuinely hold up in brighter spots, while classic fancy-leaved types are happiest in the shade of a porch.
Anecdotes & grower lore
Community experience and cultural notes — not horticultural guarantees. Conditions vary by home; treat these as colour, not prescriptions.
Caladium fans speak of the annual 'will it wake up?' suspense — a pot that looks utterly empty all winter, then pushes up its first improbably colorful leaf once the warmth returns. Gardeners in cold climates trade methods for storing the tubers like treasured seeds over winter, and there is genuine regional pride around the Florida fields where so many named varieties originate. Newcomers are often startled the first time the whole plant melts away in autumn, not realizing it is simply resting.
