Anthurium macrophyllum (Sw.) Schott

• Genus: Anthurium
• Botanical Background: Described by Swartz and later classified by Schott. Its name, "macrophyllum," refers to its notably large leaves, a characteristic feature of this species.

• Geographical Range: Native to the tropical regions of South America, particularly within the rainforests of Colombia, Ecuador, and Venezuela.
• Environment: Thrives in high-humidity environments, preferring shaded, moist conditions typically found in rainforests. It naturally grows at lower altitudes and is adapted to rich, well-draining soils.

Leaves

• Large, broad, ovate leaves with a smooth texture
• Leaves can grow up to 1 meter in length
• Bright green with a glossy, leathery texture
• The size and glossy nature of the leaves are standout features

Inflorescence (Spadix & Spathe)

• Typically white or cream-colored spathe, with a contrasting yellow or green spadix
• The spadix is usually about 10-15 cm long
• Mild fragrance
• Pollination is generally achieved via wind and insect interactions in its natural habitat

Growth Habit

• Terrestrial plant, typically growing close to the forest floor
• May climb nearby vegetation when mature
• Forms a rhizomatic structure, allowing it to propagate via its underground stems

Light Requirements

• Bright; indirect light
• Avoid direct sunlight to prevent leaf scorch

Watering & Humidity

• Keep the soil consistently moist with excellent drainage to avoid waterlogging
• High humidity is essential for optimal growth
• Ideal for greenhouses or homes with high humidity

Soil & Potting Mix

• A rich, well-draining mix containing organic matter like peat or coconut coir
• A slightly acidic to neutral pH is preferred

Temperature & Fertilizer

• Ideal temperatures between 18-24°C (65-75°F)
• Balanced water-soluble fertilizer monthly during the growing season

Division and Cuttings

• Division of the rhizomes or stem cuttings
• Ensuring each section has at least one healthy node

Seeds

• Not commonly propagated by seed

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering can lead to root rot or fungal infections
• Proper drainage and careful watering are essential

Treatment Recommendations

• Organic treatments like neem oil or insecticidal soap are effective for controlling pest infestations
• Adjust watering practices and improve air circulation to prevent fungal issue
• Use chemical treatments sparingly when necessary

• Prized for its aesthetic appeal in tropical and subtropical gardens, and it is often found in botanical collections
• Large leaves can become impressive focal points in plant displays

• Highly valued for its unique and large, glossy foliage
• A great addition to ornamental gardens or as a houseplant

Wild Population Status

• Currently not listed as endangered
• Habitat destruction could pose future risks to its natural populations

Market Availability

• Moderately available in the ornamental plant trade
• May be more challenging to find in some regions
