is elephant ear plant poisonous to humans Alocasia 'Calidora' | Giant Tropical Indoor Plant

The Alocasia 'Calidora', also known as Elephant Ear 'Calidora', is a herbaceous perennial hybrid from the Araceae family. This tropical plant is prized for its massive, attractive, and very tropical-looking leaves. It brings a spectacular touch and majestic allure to any interior or garden during the warm season.

Key Features

• Foliage: Very large, glossy, bright green leaves, arrow-shaped and strongly ribbed.
• Habit: Upright and erect, with clusters of long stems, forming a very attractive and imposing vase-shaped silhouette.
• Growth: Moderate.
• Care: Moderate to high. Requires specific light, water, and temperature conditions to thrive.
• Appeal: Primarily cultivated for the impressive size and very tropical appearance of its foliage, which makes it a striking focal point.

Care Tips

• Light: Prefers bright indirect light or dappled/partial sunlight. Avoid intense afternoon direct sun that can scorch the leaves. Indoors, place it near a bright window but protected from direct rays.
• Watering: Water regularly to keep the soil moist but well-drained. The soil should never be waterlogged to prevent root rot. Reduce watering in winter.
• Soil: Plant in a well-aerated and well-drained potting mix, rich in organic matter, that retains some moisture. An Aroid mix (such as equal parts coco coir, perlite, and orchid bark) is ideal.
• Humidity: Thrives in high humidity conditions, with humidity above 50%, ideally over 60%. A humidifier or grouping with other plants can help.
• Temperature: Prefers warm temperatures, ideally between 18°C and 29°C (65°F to 85°F). It is sensitive to cold and should never be exposed to temperatures below 10°C (50°F). Avoid cold drafts and sudden temperature changes.
• Fertilization: Fertilize every 1 to 2 months in spring and summer with a balanced fertilizer. Reduce fertilization and watering in winter.
• Pruning: Pruning is not strictly necessary, but old or damaged leaves can be removed to maintain aesthetics and redirect the plant's energy.
• Propagation: Primarily by division of offsets.
• Repotting: Repot every 2 to 3 years, or when the plant is root-bound, in spring. Choose a slightly larger pot with good drainage holes.

Caution: Alocasia 'Calidora' is considered toxic (moderate toxicity) to humans and pets if ingested. All parts of the plant (flowers, fruits, leaves, roots, sap/juice, stems, seeds) contain calcium oxalate crystals that can cause painful irritation of the lips, mouth, tongue, and throat after chewing; difficulty speaking; nausea and diarrhea, vomiting, delirium, and death. Contact with the sap can also cause dermatitis. Handle with extreme caution and keep out of reach of children and animals.
