Anthurium atrovinosum Temponi, Hammes & Nadruz

• Genus: Anthurium
• Botanical Background: Described by Temponi, Hammes, and Nadruz, contributing to ongoing botanical research into the diversity of aroids. It builds on historical studies of Anthurium diversity in tropical ecosystems

• Geographical Range: Native to tropical rainforests
• Environment: Thrives in high humidity and well-drained, organically rich soils; favors stable, warm climates with moderate rainfall, typical of tropical lowland regions

Leaves

• Leaves are typically broad and heart-shaped
• Featuring a smooth texture
• Pronounced dark venation
• Creates a striking contrast against the green background

Inflorescence (Spadix & Spathe)

• Marked by a contrasting spathe and spadix. 
• Spathe often exhibits a subtle color gradient while the spadix serves as an efficient structure for attracting pollinators through its shape and, occasionally, a mild scent

Growth Habit

• Primarily terrestrial, developing from a robust rhizome that supports its clump-forming habit
• Does not climb, although its structure can accommodate partial epiphytic growth in natural settings

Light Requirements

• Bright, indirect light

• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Regular watering is essential, keeping the soil consistently moist but not waterlogged. 
• High ambient humidity enhances its natural growth, making it ideal for greenhouse or indoor cultivation with humidifiers

Soil & Potting Mix

• A well-aerated, peat-based mix enriched with organic matter and perlite is recommended.
• Containers with good drainage help mimic its natural habitat

Temperature & Fertilizer

• The species thrives in warm temperatures, typically between 70°F and 85°F
• A balanced, diluted fertilizer applied monthly during the growing season supports its development

Division and Cuttings

• Most effectively done through division of the rhizome
• Carefully separating a portion with established roots allows for successful new plant development

Seeds

• Less common due to lower germination rates and longer establishment times compared to vegetative methods

Typical Issues

• Spider mites and mealybugs
• Overwatering may lead to root rot

Treatment Recommendations

• Effective treatments involve the use of insecticidal soap or neem oil for pest control and adjusting watering practices to avoid excessive moisture

• Organic fungicides can be applied if fungal infections are detected

• The species has generated interest for its rarity and unique appearance, making it a subject of both scientific study and horticultural curiosity. Enthusiasts value it for its potential to bring a touch of tropical elegance to indoor collections

• Collectors prize Anthurium atrovinosum for its unusual leaf patterns and elegant inflorescence, which add distinctive decorative appeal to curated plant collections

Wild Population Status

• Could be susceptible to habitat loss and requires conservation attention

Market Availability

• Remains a rare find in the horticultural trade, primarily available through specialist growers and botanical collections
