Caladium ‘Selma’ is a visually striking plant known for its vibrant, distinctive foliage. Its large, heart-shaped leaves display a unique combination of white, green, and red hues. White leaves are often accented with prominent green veins and a captivating red center, adding a tropical touch to any space.
Caring for Caladium ‘Selma’
Caladium ‘Selma’ flourishes in bright, indirect light. Direct sunlight can scorch its delicate leaves, causing brown edges or burnt spots. Insufficient light may cause the plant’s vibrant variegation to fade. Position the plant near an east-facing window or filtered sunlight to maintain its striking appearance.
Consistent soil moisture is important for Caladium ‘Selma’, but avoid overwatering to prevent tuber rot. The soil should remain evenly moist, feeling damp to the touch, but never waterlogged. Allow the top inch or two of soil to dry out between waterings. Wilting leaves signal too much or too little water; checking soil moisture is key.
Caladium ‘Selma’ prefers a rich, well-draining potting mix with a slightly acidic pH, ideally between 5.5 and 6.5. A mix of peat, perlite, or compost promotes good drainage and moisture retention. Incorporating organic matter, such as mushroom compost, can further enhance soil structure and fertility.
As a tropical plant, Caladium ‘Selma’ thrives in warm temperatures and high humidity. Ideal daytime temperatures range from 70°F to 85°F, with nighttime temperatures not dropping below 60°F. Maintaining 60-75% humidity is beneficial, achievable with a pebble tray or humidifier. Grouping plants can also increase localized humidity through transpiration.
During the active growing season, Caladium ‘Selma’ benefits from regular fertilization. Apply a liquid fertilizer, diluted to half strength, every two to four weeks for robust foliage growth. Fertilizers with a lower nitrogen ratio and higher in phosphorus and potassium are recommended, as excessive nitrogen can reduce leaf color intensity. Cease fertilization as the plant prepares for dormancy in the fall.
Planting Caladium ‘Selma’
Plant Caladium ‘Selma’ bulbs in spring after the last frost, once soil temperatures reach at least 70°F. Planting in cooler soil can lead to slow growth or tuber rot. For outdoor planting, select a location with filtered sunlight, bright indirect light, or partial shade to protect the plant from intense afternoon sun.
When planting tubers, place them about 2 inches deep in the soil with the “eyes” or growing points facing upward. If the bulb’s orientation is unclear, planting it on its side will still allow it to sprout. Space individual tubers 8 to 12 inches apart for foliage development. After planting, water generously to settle the soil.
Overwintering Caladium ‘Selma’
Caladium ‘Selma’ is a tropical perennial, not cold-hardy, requiring special care in regions with freezing winters. As fall approaches and temperatures drop, the plant naturally enters dormancy, indicated by its leaves dying back. This signals preparation for overwintering.
To store tubers, dig them up before the first hard frost, ideally when temperatures are consistently below 60°F but above 50°F. Remove excess soil and air dry them in a warm, well-ventilated area for one to two weeks. Once dried, cut off any remaining foliage about an inch above the tuber. Store cleaned, dried tubers in a cool, dry, dark place at 60°F. Packing them in dry peat moss, perlite, or vermiculite helps prevent rot or desiccation; avoid plastic bags.
Addressing Common Caladium ‘Selma’ Issues
Wilting leaves often indicate water issues (too much or too little) or exposure to extreme temperatures. Check soil moisture and adjust watering practices. Ensuring the plant is in a location with stable temperatures also helps.
Yellowing leaves signal overwatering, poor drainage, or root rot. A nutrient deficiency or natural aging of leaves can also cause yellowing. Improve drainage and allow the topsoil to dry between waterings.
Dull variegation typically points to insufficient light. Move the plant to a location with bright, indirect light to restore its characteristic color patterns. Direct sun, however, can fade colors and scorch leaves.
Caladium ‘Selma’ can experience common houseplant pests like spider mites, aphids, or thrips. Regularly inspecting the plant, especially the undersides of leaves, helps in early detection. Prompt intervention with insecticidal soap or neem oil can manage most infestations.
