Leucocasia gigantea (Blume) Schott

• Genus: Leucocasia 
• Botanical Background: First described by Carl Ludwig Blume in 1827 and reassigned by Heinrich Wilhelm Schott in 1857, this species attracted early botanical interest for its impressive foliage and unique taxonomy challenges among aroids.

• Geographical Range: Endemic to the humid lowland rainforests of Borneo, Sumatra, and Peninsular Malaysia.
• Environment: Thrives in shaded understories with consistently high humidity (70–90%), warm temperatures (20–30°C), and rich, well‑draining organic soils.

Leaves

• Massive
• Peltate leaves can exceed 2 meters in length
• Featuring a glossy, dark green surface with deep veins and a heart- or arrowhead-shape

Inflorescence (Spadix & Spathe)

• Produces a typical aroid spadix enclosed by a greenish-white spathe
• Blooms are short-lived, lightly scented, and pollinated by specific beetle species

Growth Habit

• A terrestrial perennial with a robust rhizome
• Capable of forming large clumps over time

Light Requirements

• Prefers bright, indirect light
• Tolerates partial shade but avoids direct midday sun to prevent leaf burn

Watering & Humidity

• Keep soil evenly moist without waterlogging
• High humidity (≥70%) is essential to prevent leaf edges from browning

Soil & Potting Mix

• Use a rich, chunky mix high in organic matter (e.g., peat, composted bark) with excellent drainage
• Large containers recommended to accommodate rhizome growth

Temperature & Fertilizer

• Ideal temperatures range from 20–30°C
• Feed monthly during the growing season with a balanced liquid fertilizer at half-strength

Division

• Divide rhizomes during active growth
• Ensure each division has at least one growing point

Stem Cuttings (if applicable)

• Stem cuttings are less common

Seeds

• Seeds are rarely used
• Germination requires consistent warmth (25°C), high humidity, and moist, sterile media

Typical Issues

• Susceptible to spider mites, mealybugs, and root rot from overwatering
• Maintain good air circulation and avoid waterlogged conditions

Treatment Recommendations

• Use insecticidal soap or neem oil for pests
• Treat root rot by trimming affected roots, repotting in fresh mix, and reducing watering frequency

• Known for producing the largest leaves among aroids
• Plays an ecological role by providing shelter for understory fauna

• Highly prized for its dramatic foliage and size
• Making it a focal point in tropical-themed gardens and conservatories

Wild Population Status

• Not currently listed as threatened, but habitat loss from deforestation poses potential risks to wild populations

Market Availability

• Moderately available through specialty nurseries and aroid collectors 
• Mature specimens are rare and can be expensive
