Colocasia ‘Beauty’ is an ornamental plant prized for its striking foliage. This tropical native showcases large, heart-shaped leaves with a deep purple to almost black coloration and prominent dark veins. Its dramatic appearance makes it a popular choice for bold visual statements.
Caring for Colocasia ‘Beauty’
Colocasia ‘Beauty’ thrives in consistent environmental conditions. It performs best in bright, indirect light or partial shade. While some direct morning sun is acceptable, intense afternoon sun can cause foliage to fade or scorch.
The plant prefers rich, well-draining soil that remains consistently moist. A suitable potting mix includes peat moss, perlite, and compost, which help retain moisture while ensuring adequate drainage. For container planting, select a pot with drainage holes to prevent waterlogging and root issues.
Colocasia ‘Beauty’ requires consistently moist, but not saturated, soil. Allowing the soil to dry out completely between waterings can stress the plant and lead to brown leaf tips. During the active growing season in spring and summer, daily watering may be necessary, especially for outdoor plants or those in warmer climates.
As a tropical species, Colocasia ‘Beauty’ flourishes in warm, humid conditions. Ideal temperatures range from 65°F to 90°F (18°C to 32°C); temperatures below 50°F (10°C) can cause damage. High humidity is beneficial for lush growth, especially indoors where misting or humidifiers can be used.
Colocasia ‘Beauty’ is a heavy feeder, benefiting from regular nutrient supplementation during its active growth phase. Apply a balanced, water-soluble fertilizer with an N-P-K ratio like 20-10-20 or 20-20-20 every two to four weeks to support robust growth. Dilute the fertilizer to prevent nutrient burn and ensure the soil is moist before application.
Pruning involves removing yellowed or damaged leaves to maintain the plant’s appearance and health. This redirects the plant’s energy to new growth. Wait until leaves are fully dried and crisped before removal, as the plant can still draw energy from them.
Propagating Colocasia ‘Beauty’
Colocasia ‘Beauty’ can be propagated through the division of its underground corms or tubers. This method is performed in early spring as the plant begins to show new growth. To propagate, carefully dig up the entire plant, taking care not to harm the corms or root system.
Once unearthed, separate the smaller cormels or offsets that have formed around the main corm. Each separated section should have some roots and at least one “eye,” a small growth point. Plant these divisions into individual pots filled with a well-draining potting mix, ensuring the corm is at the same depth as it was previously.
Winter Care and Dormancy
In regions experiencing cold winters, Colocasia ‘Beauty’ enters a dormant phase. For overwintering, especially in USDA Zones below 8, dig up the corms before the first hard frost. Allowing the plant to experience a light frost can help it pull nutrients back into the corm.
After digging, remove excess soil and trim any remaining foliage. Dry the corms for a few days to a week to cure before storage. Store them in a cool, dark, frost-free location, such as a basement or garage, around 50-55°F (10-13°C), nestled in peat moss or dry paper to prevent desiccation and rot. Potted plants can also be brought indoors, where they may go dormant or continue to grow if kept warm with sufficient light, requiring minimal watering if dormant.
Common Problems and Solutions
Colocasia ‘Beauty’ can encounter pests like spider mites, aphids, and mealybugs, which can be managed with horticultural sprays. Slugs and snails may also be drawn to young plants, potentially damaging leaves. Monitoring for these pests and addressing them promptly helps maintain plant health.
Physiological problems stem from improper care. Yellowing leaves can indicate overwatering, leading to root rot, or underwatering, causing stress. Brown leaf edges signify insufficient moisture, while stunted growth might point to a nutrient deficiency, highlighting the need for consistent watering and fertilization. Proper soil drainage helps prevent many of these issues.
Toxicity and Safety
Colocasia ‘Beauty’, like other plants in its genus, contains calcium oxalate crystals. These crystals make the plant toxic if ingested, leading to irritation of the mouth, throat, and digestive tract.
When handling Colocasia ‘Beauty’, particularly during pruning or propagation, wear gloves to prevent skin irritation. Keep the plant out of reach of children and pets to avoid accidental ingestion.
