Anthurium platyrhizum Croat

• Genus: Anthurium
• Botanical Background: Described by the renowned botanist Thomas Croat, whose extensive work on tropical aroids has contributed significantly to our understanding of Anthurium diversity.

• Geographical Range: Native to the tropical rainforests of South America, this species is part of a rich ecosystem characterized by high biodiversity and complex vegetation layers.
• Environment: Thrives in warm, humid conditions with well-drained, organic-rich soils; favors environments with consistent moisture and filtered light, typical of forest understories.

Leaves

• Large, broad
• Paddle-like with a leathery texture and subtle veining
• Their deep green coloration and distinctive shape make them a standout feature

Inflorescence (Spadix & Spathe)

• Composed of a spadix surrounded by a modest spathe, generally displaying muted greenish or brownish tones
• Scent is minimal
• Structure is adapted for specific insect pollinators

Growth Habit

• Can grow as either an epiphyte or a terrestrial plant
• Develops a rhizomatous system that supports its vigorous, spreading growth

Light Requirements

• Bright, indirect light
• Direct sunlight can scorch the leaves, while too little light may stunt its development

Watering & Humidity

• Maintain consistent soil moisture without overwatering
• High ambient humidity

Soil & Potting Mix

• A well-aerated, organic-rich potting mix that drains effectively is ideal
• An organic-rich, loose medium supports its growth and mimics natural conditions

Temperature & Fertilizer

• Temperature within a range between 65°F to 85°F (18°C to 29°C)
• Balanced, water-soluble fertilizer applied monthly during the growing season

Division and Cuttings

• Division of rhizome
• Carefully separate sections of the plant during repotting to ensure each division has viable roots and a growing tip

Seeds

• Less common due to the lower viability and more specialized germination requirements
• Need a warm and humid environment to germinate successfully

Typical Issues

• Spider mites and mealybugs
• Risk of root rot if overwatered

Treatment Recommendations

• Use mild insecticidal soap or neem oil
• Maintain a careful watering schedule and ensure good airflow

• Notable for its dramatic foliage, which has earned it attention in botanical exhibits and among collectors
• Its distinctive leaves also contribute to discussions on tropical plant adaptations

• Prized for its architectural foliage and the challenge it presents in cultivation
• Its rarity and unique appearance make it a desirable addition to specialized collections and tropical garden displays

Wild Population Status

• There are currently no major conservation concerns for this species
• Ongoing habitat loss in tropical regions remains a general threat to biodiversity

Market Availability

• Relatively rare in the commercial horticultural market
• Typically sought after by dedicated collectors and specialists
