Bidayuha crassispatha S.Y.Wong & P.C.Boyce

• Genus: Bidayuha
• Botanical Background: Studied by several prominent botanists over time, with its formal description contributing to a broader understanding of tropical aroid diversity. Historical botanical expeditions and herbarium collections have played key roles in documenting its characteristics.

• Geographical Range: Found in tropical lowland forests and seasonal rainforests within Southeast Asian regions.
• Environment: thrives in humid conditions with well-draining, organic-rich soil, favors climates that are warm and moist, with partial shade that mimics the understory of dense tropical forests.

Leaves

• Broad, thick, and glossy with a leathery texture
• Deep green coloration
• Subtle variegation or unique venation patterns

Inflorescence (Spadix & Spathe)

• Prominent spadix encircled by a sturdy spathe
• Soft hues
• Not noted for a strong scent but plays a key role in its pollination strategy

Growth Habit

• Forming clumps from a robust rhizome system; primarily terrestrial
• Suitable for container cultivation

Light Requirements

• Bright, indirect light
• Direct sun may scorch its leaves
• Too little light can diminish its vibrancy

Watering & Humidity

• Regular watering that keeps the soil consistently moist but not waterlogged
• Benefits from high humidity, mimicking its native tropical conditions

Soil & Potting Mix

• A well-draining, mix enriched with organic matter (peat, perlite, and compost)
• Containers should provide ample drainage

Temperature & Fertilizer

• Ideal temperature range is between 65°F and 80°F (18°C to 27°C)
• Fertilize monthly during the growing season with a balanced liquid fertilizer

Division

• Careful separation of clumps during repotting encourages new growth

Seeds

• Less common due to variable germination rates and a longer period to maturity

Typical Issues

• Spider mites, aphids, and mealybugs
• Overwatering can lead to root rot

Treatment Recommendations

• Insecticidal soap or organic remedies to manage pest
• Ensure prompt correction of watering practices and use fungicidal treatments

• Bidayuha crassispatha has inspired local folklore due to its unusual appearance
• Its robust morphology also plays a role in stabilizing soil in its native habitat

• Favorite in tropical plant collections for ease of cultivation and striking foliage and unique inflorescence

Wild Population Status

• Not currently classified as endangered but faces habitat pressures from tropical deforestation

Market Availability
