Anthurium atroguttatum Croat

• Genus: Anthurium
• Botanical Background: Described by renowned botanist Thomas Croat, Anthurium atroguttatum has helped expand the understanding of leaf pattern diversity within the genus.

• Geographical Range: Indigenous to the tropical rainforests of parts of South America
• Environment: Thrives in humid, shaded understories with well-draining, organic-rich soils and moderate temperatures, typical of tropical rainforest climates

Leaves

• Broad, lanceolate leaves
• Glossy texture 
• Distinctive dark spots that create a dramatic contrast against the vibrant green

Inflorescence (Spadix & Spathe)

• Subtle, often greenish or white spathe paired with a spadix that, while not strongly scented, plays a crucial role in attracting pollinators

Growth Habit

• Exhibits a terrestrial growth habit, forming clumps from a robust rhizome, though it can occasionally display epiphytic tendencies in its native habitat

Light Requirements

• Bright, indirect light to maintain its vibrant foliage without risking leaf scorch

Watering & Humidity

• Keep the soil consistently moist with regular watering
• Ensure high ambient humidity to mimic its natural environment

Soil & Potting Mix

• Use a well-draining, organic-rich mix designed for aroids
• Epiphytic plants to support healthy root development

Temperature & Fertilizer

• Maintain temperatures between 65°F and 80°F

• Apply a balanced liquid fertilizer during the growing season to encourage robust growth

Division & Cutting

• Most common propagation method is through division of the rhizome during repotting, which helps maintain genetic fidelity and vigor

Seeds

• Less common due to slower germination and growth rates

Typical Issues

• Spider mite and mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Employ insecticidal soap or neem oil for pest control
• Ensure proper drainage to prevent fungal infections and maintain plant health

• Unusual dark spotting not only enhances its visual appeal but also highlights the evolutionary diversity within the Anthurium genus

• Prized for its distinctive foliage and rarity; serves as a standout ornamental specimen in tropical plant collections

Wild Population Status

• Conservation data is limited, ongoing habitat loss in tropical regions suggests that wild populations could be under pressure

Market Availability

• Rlatively rare in cultivation, often available only through specialist nurseries or botanical exchanges, making it a coveted addition for collectors
