The Moonlight Caladium is easily recognizable by its large, heart-shaped leaves that boast a silvery-white hue with delicate green veins. Its leaves grow on tall, slender stems, creating a mesmerizing display.

The plant is often mistaken for other indoor plants with similar foliage, such as other varieties of Caladium, Alocasia, and Colocasia.


Moonlight Caladiums are known for their dramatic foliage, with individual leaves reaching up to 8-12 inches (20-30 cm) in length. The plant itself has an upright, clump-forming growth habit, making it an ideal choice for adding height and visual interest to indoor spaces.

It typically grows to a height of 1-2 feet (30-60 cm), with a similar spread. Over time, the plant will produce additional stems and leaves, gradually expanding in size and creating a lush, tropical atmosphere.

Light Requirements

This stunning plant thrives in medium to bright, indirect sunlight. Direct exposure to harsh sun rays can scorch its delicate leaves, while insufficient light can lead to reduced growth and dull, lackluster foliage.

Ideal locations for the Moonlight Caladium include east or west-facing windows, or a few feet away from a south-facing window. Alternatively, you can use a sheer curtain to filter the sunlight and protect the plant from harsh rays.

Temperature Requirements

Moonlight Caladiums prefer warm temperatures, ranging from 65-85°F (18-29°C). To ensure healthy growth, maintain a consistent temperature and avoid exposing the plant to drafts or sudden temperature fluctuations. During the winter months, be sure to keep your Caladium away from cold windows and heating vents to prevent temperature-related stress.

Humidity Requirements

This tropical beauty thrives in high humidity environments, with an ideal range of 60-80%. To maintain adequate humidity, you can place the plant on a tray filled with water and pebbles, or use a humidifier to increase the moisture in the air. Signs of insufficient humidity include brown leaf tips or curling leaves, while excessive humidity can lead to fungal issues.

Watering Requirements

The Moonlight Caladium requires even soil moisture to thrive. Water the plant when the top inch of soil begins to feel dry, being careful not to overwater or let it sit in standing water.

During the growing season, the plant may need more frequent watering, while in the winter months, you can reduce the watering frequency as the plant enters dormancy.

Overwatering can lead to root rot, yellowing leaves, and a wilted appearance, while underwatering may result in dry, crispy leaves.

Fertilizing Requirements

Feeding your Moonlight Caladium with a balanced liquid fertilizer diluted to half strength every 4-6 weeks during the growing season will promote lush foliage and vigorous growth.

Refrain from fertilizing during the winter months when the plant is dormant. Signs of under-fertilization include slow growth and pale leaves, while over-fertilizing may cause leaf burn or excessive growth at the expense of leaf color.

Soil Requirements

A well-draining, peat-based potting mix is ideal for Moonlight Caladiums. The soil should retain moisture without becoming waterlogged. Adding perlite, vermiculite, or orchid bark to the potting mix can improve drainage and aeration, promoting healthy root growth and preventing root rot.

Diseases & Pests

Moonlight Caladiums are susceptible to several common indoor plant diseases and pests:

  • Root rot: Caused by overwatering or poor drainage
  • Fungal infections: Occur due to excessive humidity or poor air circulation
  • Aphids: Small, sap-sucking insects that can cause leaf distortion and yellowing
  • Spider mites: Tiny pests that create web-like structures on the plant and cause stippling on the leaves
  • Mealybugs: Soft-bodied insects that leave a white, cottony residue on the plant

Implement proper plant care and monitor your Caladium regularly to prevent and address these issues.


Moonlight Caladiums are toxic to both humans and pets due to the presence of calcium oxalate crystals. Ingestion can cause irritation of the mouth, throat, and gastrointestinal tract.

Keep the plant out of reach of children and pets to avoid accidental consumption. If ingestion occurs, contact a healthcare professional or veterinarian immediately.

Common Problems

Some common problems and their solutions include:

  • Yellowing leaves: Overwatering or poor drainage
  • Brown leaf tips: Low humidity or underwatering
  • Pale or dull leaves: Insufficient light or under-fertilization
  • Leaf burn: Over-fertilization or direct sunlight exposure
  • Drooping leaves: Underwatering, overwatering, or temperature stress

Addressing these issues promptly will ensure the health and vitality of your Moonlight Caladium.


Caring for a Moonlight Caladium can be a rewarding experience, resulting in a captivating indoor display of striking foliage. By following this comprehensive care guide, you’ll be well-equipped to provide your plant with the ideal conditions it needs to thrive.
