Light and placement

Provide bright filtered light, partial shade, or shade with some gentle morning sun. In hot climates, protect the leaves from harsh afternoon sun, which can scorch or fade tender foliage. Too little light may produce elongated petioles and a thin display; excessive direct sun can cause bleaching, scorch, and loss of pattern. Rotate indoor containers periodically for even growth.

Watering and humidity

Water thoroughly when the surface begins to dry, then let excess drain completely. Keep the root zone evenly moist during warm active growth, increasing frequency in containers, heat, or bright locations. Reduce watering as leaves yellow in fall, and keep dormant tubers nearly dry enough to prevent rot. Do not allow the pot to stand in a saucer of water.

Soil and growing medium

Use a loose, fertile, moisture-retentive but well-drained mix. A peat-free container mix amended with compost and coarse material works well. Caladiums generally perform best in acidic to slightly acidic media; avoid compacted soil and standing water. A practical target is about pH 5.5–6.5, although the exact optimum can vary with the growing system.

Feeding

Feed during active growth after shoots emerge, using a balanced controlled-release fertilizer or a dilute liquid fertilizer according to the product label. Caladiums benefit from modest, regular nutrition rather than heavy applications. Do not fertilize dormant tubers, freshly divided pieces, or plants growing in cold, waterlogged soil.

Growth and habit

Growth is rapid when tubers receive warm soil, steady moisture, and adequate light. The plant forms a dense display of upright petioles from a central tuber. Avoid repeated drought because wilting can interrupt growth and encourage dormancy; avoid dense, wet conditions that favor tuber decay.

Planting

Planting and repotting

Planting timeLate spring, after frost danger and once soil reaches 60–70°F
Planting depthAbout 2 inches for dormant tubers; set potted plants at existing soil level
Spacing8–12 inches apart

Plant dormant tubers outdoors only after frost danger has passed and the soil is consistently about 60–70°F. Set the puckered, knobby growing side upward, about 2 inches deep, and space plants roughly 8–12 inches apart for a fuller display. Water after planting and mulch lightly once foliage emerges.

Repotting

Repot or transplant only when temperatures are warm and active growth is beginning. Move the tuber or rooted plant with minimal disturbance, keeping the growing point oriented upward. Choose a container with drainage holes and avoid excessive empty soil around a dormant tuber, which can stay wet and rot.

Practical tasks

Propagation and pruning

Propagation

Propagate by division of healthy tubers. Separate tuber sections only when each piece has at least one viable eye, allow fresh cuts to dry briefly, and plant in warm media. Commercial production relies on asexual propagation to maintain the cultivar’s traits; seed is not a reliable way to reproduce it true to type.

Pruning

No routine pruning is needed. Remove yellowing, damaged, or diseased leaves at the base with clean shears. Allow foliage to decline naturally at the end of the season so the tuber can recover reserves; cut back only after leaves have yellowed or died.

Seasonal care

Overwintering

Dig tubers after foliage declines and before frost in climates colder than Zone 9. Let them dry for 1–3 days in a shaded, ventilated place, then store them in a dry medium such as vermiculite at roughly 60–70°F. Keep dormant tubers above cold, damp conditions and replant only after warm spring soil returns.

Practical use

Uses

Use ‘Raspberry Moon’ as a foliage accent in shaded beds, mixed containers, hanging displays, patios, and sheltered entry areas. It is especially useful where flowers are less dependable than colorful leaves. It is not an edible plant, and all parts should be kept away from children and pets because of calcium oxalates.

Identification and habit

Appearance

This fancy-leaf cultivar produces broad, heart-shaped to ovate leaves on upright petioles. Its foliage combines raspberry-red blotches and speckles with chartreuse or light-green areas and darker green markings. Pattern intensity can change with light, temperature, and plant maturity, so individual leaves may vary while retaining the cultivar’s characteristic multicolored appearance.

Flowering

Inconspicuous arum-type inflorescences; ornamental value is in the leaves
Flower colors
Greenish to cream inflorescence, not showy
Flower form
Spathe and spadix inflorescenceFlower form
ScentNo notable fragrance
Flower sizeSmall and inconspicuous

Caladiums can produce small arum-family inflorescences consisting of a spathe and spadix, but flowering is inconspicuous and not the reason this cultivar is grown. ‘Raspberry Moon’ is selected primarily for its foliage, and reliable cultivar-specific flowering dates are not documented.

Ecological relationships

Pollination and visitors

No reliable cultivar-specific record was found documenting a characteristic animal pollinator or visitor for ‘Raspberry Moon’. The small arum-type inflorescences are secondary to the ornamental foliage, so no pollinator group is assigned.

Plant protection

Diseases and pests

Diseases

The main risks are tuber rot and fungal or bacterial problems encouraged by cold, saturated soil, damaged tubers, or poor sanitation. Plant only firm, healthy tubers in warm, well-drained media; avoid overwatering and remove collapsing or diseased material promptly. Good air movement and clean tools reduce spread.

Pests

Watch for aphids, thrips, spider mites, mealybugs, and caterpillars, particularly on stressed container plants. Inspect leaf undersides and new growth, isolate affected plants, and use a strong water spray or an appropriately labeled insecticidal soap or horticultural oil when needed. Avoid treating drought-stressed or heat-stressed foliage.

Safety and allergens

Toxicity and pollen

ToxicityToxic to people and pets if chewed or swallowed

Caladium contains insoluble calcium oxalate crystals. Chewing or ingesting leaves, stems, or tubers can cause immediate burning and irritation of the mouth, drooling, swelling, vomiting, and difficulty swallowing. Keep the plant away from children and pets, wash hands after handling damaged tissue, and seek professional poison-control or veterinary advice after ingestion.

Pollen and allergyLow airborne-pollen concern
Typical season
No specific exposure season is documented for this cultivar.
Pollination / pollen
Limited, locally released pollen from inconspicuous inflorescences

This cultivar is grown for foliage and has inconspicuous inflorescences. No cultivar-specific airborne-pollen measurements or allergy studies were located. Because the flowers are not prominent and pollen exposure is not documented as a major issue, a low concern label is used rather than claiming zero risk.

Dogs Toxic; may cause oral irritation, drooling, vomiting, and swallowing difficulty.
Cats Toxic; insoluble calcium oxalates can cause painful oral irritation and swelling.
Children Toxic if chewed or swallowed; causes irritating calcium-oxalate exposure.
Affected plant parts Leaves, petioles, tubers, and other plant tissues
Natural environment

Native habitat

The cultivated hybrid derives from tropical Caladium lineages associated with warm, humid habitats of the Amazon Basin. In cultivation it prefers warm soils, filtered or partial light, organic-rich moisture-retentive media, and protection from cold. It does not tolerate frost and commonly becomes dormant as temperatures decline.
