Alocasia alba Schott

• Genus: Alocasia
• Botanical Background: Described by botanist Heinrich Wilhelm Schott in the 19th century. Its unique morphology has made it an important subject of study within the Araceae family.

• Geographical Range: Native to tropical regions of Southeast Asia, including the Philippines, Malaysia, and parts of Indonesia.
• Environment: Thrives in warm, humid environments, typically found in lowland rainforests; prefers shaded areas with high humidity, moist but well-drained soils, and moderate temperatures.

Leaves

• Large and heart-shaped
• Exhibit striking white and green variegation
• Texture is smooth
• Size can reach up to 40 cm in length

Inflorescence (Spadix & Spathe)

• Spathe is a pale greenish hue
• Scent is not particularly notable
• Spadix is a typical feature, but rarely flowers in cultivation

Growth Habit

• Terrestrial plant
• Growing from a rhizome
• Can reach heights of up to 1 meter under optimal conditions
• Spreads in a bushy, upright fashion

Light Requirements

• Bright, indirect light
• Place it near a window with filtered light

Watering & Humidity

• Consistently moist soil but does not tolerate waterlogging
• High humidity levels of 60-80%

Soil & Potting Mix

• A well-draining, slightly acidic mix such as a peat-based potting soil with added perlite or orchid bark
• Ensure the pot has drainage holes
  

Temperature & Fertilizer

• Temperatures range from 18°C to 26°C (65°F to 80°F)
• Fertilize during the growing season (spring and summer) with a balanced liquid fertilizer every 2-4 weeks

Division and Stem Cuttings

• Most common propagation method is rhizome division
• Separate a healthy rhizome with at least one growing shoot and replant it in moist, well-draining soil

Seeds

• Less common in cultivation
• Requires warmth and high humidity

Typical Issues

• Aphids, spider mites, and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure proper drainage
• Avoid overwatering
• Remove affected parts of the plant and treat with fungicide
  

• Used in traditional medicine in some Southeast Asian cultures
• Primarily grown for its ornamental value

• Referred to as "elephant ear" due to its large, dramatic foliage
• Variegated foliage and ornamental beauty
• Unique leaf coloration and its relatively easy-care requirements

Wild Population Status

• Not currently listed as endangered
• Native habitats are increasingly threatened by deforestation and urbanization

Market Availability

• Occasionally found in specialty nurseries
• May be considered rare or hard to find
• Commonly cultivated in tropical regions for ornamental purposes
