Light and placement

Place in bright filtered light, morning sun, or open shade with protection from intense afternoon rays. Too much direct sun can scorch or bleach the leaves, especially in hot climates; too little light may produce weaker petioles and less vivid color. Indoors, an east-facing window or bright spot set back from a south- or west-facing window is usually suitable.

Watering and humidity

Water thoroughly when the upper surface begins to dry, then allow excess water to drain fully. During warm active growth, do not let the mix dry completely; containers may need frequent checks in summer. Reduce watering as leaves yellow and dormancy approaches, and keep dormant tubers only slightly dry rather than continuously wet. Humidity helps indoors, but stagnant air and wet foliage encourage disease.

Soil and growing medium

Use a loose, moisture-retentive but well-drained mix rich in organic matter. A quality peat- or coir-based potting mix amended with compost and perlite works well in containers. Slightly acidic to neutral conditions are suitable; avoid compacted, waterlogged soil, which can rot the tuber.

Feeding

Feed during active growth with a balanced, water-soluble fertilizer diluted to half strength every 3–4 weeks, or use a controlled-release product according to its label. Incorporate compost before planting if soil is poor. Do not fertilize dormant, cold, or recently rotted tubers, and avoid heavy nitrogen that can produce soft, weak growth.

Growth and habit

Growth begins from a tuber once warmth and moisture return. The plant forms a compact clump of upright, long-petioled leaves and usually grows most vigorously through the warm season. In cooler climates, foliage declines naturally in autumn; reducing water as dormancy begins helps prevent tuber loss.

Planting

Planting and repotting

Planting timeLate spring, after frost, when soil is warm
Planting depth1.5–2 inches
Spacing6–12 inches

Plant outdoors after the danger of frost has passed and soil temperatures are reliably warm, typically in late spring. Set tubers with the eyes facing upward, about 1.5–2 inches deep, and space plants 6–12 inches apart. Water after planting and keep the bed evenly moist while shoots establish.

Repotting

Repot or transplant only when active growth is beginning and temperatures are warm. Handle the tuber and emerging shoots gently, and use a container with drainage holes. Move up only one pot size at a time to avoid excess wet mix around the roots.

Practical tasks

Propagation and pruning

Propagation

Propagate commercially and practically by division of dormant tubers or by separating tuber sections that contain viable eyes. Plant divisions in warm, lightly moist medium in spring. Seed propagation is possible for caladiums but will not reliably reproduce a named cultivar.

Pruning

Remove yellowing, damaged, or diseased leaves at the base with clean scissors. If an inflorescence appears, it may be removed to keep the plant focused on foliage and tuber development, although leaving it is not usually harmful.

Seasonal care

Overwintering

In USDA Zones 9 and colder, lift tubers after foliage declines or before freezing weather. Dry them briefly, remove loose soil, and store around 60–70°F in a dry, ventilated medium such as dry peat, vermiculite, or paper. Alternatively, move container plants indoors and keep them warm; dormancy may still occur.

Practical use

Uses

Use 'Pink Symphony' in shaded summer borders, porch pots, patio containers, window boxes, and warm indoor displays. Its compact strap-leaved habit suits small spaces and mixed shade plantings. It is ornamental only; do not use it as food or medicine. Handle with gloves if sap sensitivity is a concern.

Identification and habit

Appearance

The cultivar has small, strap- or lance-shaped leaves carried on slender petioles. Leaves are predominantly pink, with clearly contrasting green veins and typically a green margin. The narrow foliage distinguishes it from broad fancy-leaved caladiums. Color intensity can vary with light, temperature, plant age, and growing conditions.

Flowering

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
Flower colors
Greenish-white to yellow-green
Flower form
Arum-type spathe surrounding a short spadixFlower form
ScentNone documented
Flower sizeSmall, under 1 inch

Caladiums may produce a small arum-type inflorescence consisting of a spadix enclosed by a spathe, but they are cultivated primarily for foliage and flowering is occasional and inconspicuous. Cultivar-specific flowering behavior is not well documented.

Ecological relationships

Pollination and visitors

No reliable cultivar-specific documentation was found for regular animal visitors or pollinator attraction. The inconspicuous inflorescence is not a dependable wildlife feature, so no visitor group is assigned.

Plant protection

Diseases and pests

Diseases

Tuber rot and root rot are promoted by cold, saturated soil and poor drainage. Plant in warm, porous media, avoid overwatering during dormancy, and remove visibly rotting tissue. Leaf spots and blights are more likely when foliage stays wet and air circulation is poor; water at the soil line and discard badly affected leaves.

Pests

Common problems include aphids, mealybugs, spider mites, thrips, caterpillars, and slugs. Inspect leaf undersides and new growth regularly. Remove pests by hand or with a water spray when practical; use insecticidal soap or horticultural oil according to the label, avoiding treatment in hot sun. Slugs and snails are best managed with sanitation, hand-picking, and suitable barriers.

Safety and allergens

Toxicity and pollen

ToxicityModerately toxic if chewed or swallowed

Caladiums contain insoluble calcium oxalate crystals. Chewing or swallowing plant tissue can cause immediate burning, pain, swelling, drooling, nausea, vomiting, or difficulty swallowing; sap may irritate skin and eyes. Keep tubers, leaves, and sap away from children and pets, and seek poison-control or veterinary advice after ingestion.

Pollen and allergyLow airborne pollen relevance
Typical season
Not meaningfully documented for airborne exposure
Pollination / pollen
Limited release from occasional enclosed inflorescences

Caladium produces pollen only when it flowers, and its small, enclosed arum-type inflorescences are not generally regarded as a major airborne pollen source. Cultivar-specific allergen studies were not found, so low airborne relevance is a cautious horticultural classification rather than proof of zero allergy risk.

Dogs Toxic; chewing can cause oral irritation, swelling, vomiting, and difficulty swallowing.
Cats Toxic; ingestion may cause intense mouth irritation, drooling, vomiting, and swallowing difficulty.
Children Toxic if chewed or swallowed; sap may irritate skin and eyes.
Affected plant parts Leaves, stems, flowers, tubers, roots, sap, and other plant tissue
Natural environment

Native habitat

The species complex is associated with warm, humid tropical American environments and grows best in organically enriched, evenly moist soils with protection from cold. Cultivated caladiums are adapted to filtered light and warm-season conditions rather than prolonged frost or winter saturation.

Good to know

Interesting fact

This cultivar is classified among strap- or lance-leaved caladiums rather than broad fancy-leaved types. Its small pink leaves are crossed by green veins, giving the plant a delicate but high-contrast appearance. Caladiums grow from tubers and enter dormancy when conditions become cool or dry. The cultivar is recorded in commercial caladium production and extension recommendations.
