The Colocasia Royal Hawaiian ‘Waikiki’ is a tropical plant. Its large, glossy green leaves feature dramatic white centers and vivid pink veins. Its unique coloration and compact, clumping growth make it a popular choice for adding exotic flair to landscapes or containers. It typically reaches about 3 feet tall and wide.
Colocasia Royal Hawaiian Waikiki Care Essentials
Light
Colocasia Royal Hawaiian ‘Waikiki’ thrives in bright, indirect light but tolerates full sun to partial shade. In hotter climates, afternoon shade helps prevent leaf scorching. Indoors, filtered sunlight prevents leaf burn. Insufficient light diminishes variegation, while too much direct sun causes leaf burn.
Water
This plant prefers consistently moist soil. Keep the soil evenly moist, but avoid waterlogging. Watering deeply once a week is often sufficient, though more frequent watering may be necessary during hot, dry periods or if the plant is in a container. Do not allow the soil to dry out completely.
Soil
Colocasia Royal Hawaiian ‘Waikiki’ flourishes in rich, loose, and well-drained potting soil. An organically rich mix, incorporating compost or well-rotted manure, is ideal. This soil ensures good drainage and moisture retention. A slightly acidic to neutral pH (6.0 to 7.0) is preferred.
Temperature and Humidity
These tropical plants prefer warm temperatures, ideally between 60-80°F (15-27°C) during the day, and not below 60°F (15°C) at night. They are suitable for USDA hardiness zones 7b-11. High humidity is also beneficial for their growth. To increase humidity, mist the leaves regularly, place the pot on a pebble tray with water, or group it with other plants.
Fertilizer
Fertilize Colocasia Royal Hawaiian ‘Waikiki’ during its active growing season (spring and summer). A balanced, water-soluble fertilizer, such as a 20-20-20 formula, is a good option. An all-purpose fertilizer high in nitrogen can also be used. Apply fertilizer every 4-6 weeks during this period.
Planting and Placement
Colocasia Royal Hawaiian ‘Waikiki’ performs well in containers or directly in the garden. Plant in spring after the last frost and soil has warmed. For container planting, choose a pot at least 12-20 inches wide and tall to accommodate its mature size.
When planting in the ground, dig a hole twice the root ball’s width, setting the plant 1-2 inches above ground level. Backfill with amended soil and water deeply to settle the soil. Mulching around the plant, avoiding the stem, retains moisture and regulates soil temperature. Space plants 2-3 feet apart to ensure optimal growth and air circulation.
Troubleshooting Common Issues
Yellowing leaves on Colocasia Royal Hawaiian ‘Waikiki’ often indicate improper watering. Both overwatering (leading to root rot) and underwatering may result in yellowing foliage. Browning leaf edges typically signal low humidity or inconsistent watering. Increase humidity by misting or using a pebble tray.
Stunted growth might suggest a lack of nutrients during the growing season or insufficient light. Ensure adequate fertilizer and optimal light. Though generally resistant to common pests and diseases, monitor for spider mites or aphids. Treat detected pests promptly with an appropriate insecticidal soap.
Winterizing and Dormancy
In non-tropical climates (USDA Zones 7a and below), Colocasia Royal Hawaiian ‘Waikiki’ is not winter hardy and enters dormancy. Before the first frost, prepare the plant for winter storage by reducing watering as temperatures drop, allowing the soil to dry.
Once foliage dies back or after the first light frost, cut leaves and stems to a few inches above the soil line. Container plants can be moved indoors to a cool, dark, frost-free location (41-50°F / 5-10°C). For in-ground plants, dig up tubers, remove excess soil and dry for a few days before storing them in a cool, dry place, such as in peat moss or sawdust. In spring, replant tubers once temperatures rise and frost threat has passed, and watering can resume to encourage new growth.
