Anthurium geniculatum Sodiro

• Genus: Anthurium
• Botanical Background: Described by Ecuadorian botanist Luis Sodiro, Anthurium geniculatum adds to the growing number of species documented by botanists in the Araceae family, with Sodiro’s research providing significant insights into the flora of the Andean region.

• Geographical Range: Found in the lowland and montane rainforests of Ecuador and Colombia
• Environment: Prefers high humidity (70–90%) typical of tropical rainforests, Thrives in well-draining, organic-rich soils, often found in moist, shaded areas of the forest floor, Grows best in tropical climates with year-round temperatures ranging from 20°C to 28°C (68°F to 82°F), with consistent rainfall.

Leaves

• Heart-shaped, large, and leathery, with dark green coloration
• Leaves can grow up to 40 cm (16 inches) in length, with prominent veins giving them a distinct, textured appearance

Inflorescence (Spadix & Spathe)

• Spadix is typically white or pale green, cylindrical, and stands upright from the spathe
• Spathe is typically light green, wrapping partially around the spadix
• Lacks a strong scent but is visually striking, attracting pollinators like small beetles and flies

Growth Habit

• Terrestrial species that grows from a rhizome. It forms a compact, bushy clump and typically reaches a height of about 50 cm (20 inches), making it suitable for ornamental cultivation in smaller spaces or as a houseplant

Light Requirements

• Prefers bright, indirect light but can tolerate moderate shade
• Avoid direct sunlight, as it can burn the leaves

Watering & Humidity

• Keep the soil consistently moist but well-drained. Water when the top layer of soil starts to dry out
• Requires high humidity levels (60%–80%) to thrive. Mist the leaves regularly or place the plant on a humidity tray to maintain optimal moisture levels

Soil & Potting Mix

• A well-draining, organic potting mix is best. A mixture of peat, perlite, and pine bark will help retain moisture while allowing for proper drainage

Temperature & Fertilizer

• Prefers temperatures between 20°C and 28°C (68°F to 82°F)
• Avoid exposure to temperatures below 18°C (64°F)
• Apply a balanced liquid fertilizer once a month during the growing season
• Reduce fertilizing during the winter months when growth slows
  

Division

• Propagation is best done by rhizome division
• Each division should have at least one healthy root and leaf to promote successful regrowth
  

Seeds

• Seed propagation is less commonly used but possible
• Seeds require warm, humid conditions to germinate, and the process can take several months
  

Typical Issues

• Mealybugs, spider mites, aphids, and scale insects
• Overwatering can lead to root rot, and fungal infections like powdery mildew are common in overly humid environments

Treatment Recommendations

• Insecticidal soap or neem oil can be used to treat pest infestations
• A mixture of water and mild dish soap can be used to clean pests off the plant
• Ensure good airflow to reduce fungal growth and avoid excessive moisture on the leaves
  

• Plays an important role in the tropical ecosystem, supporting pollinators such as small insects
• Found in the biodiverse rainforests of the Andean region, contributing to the ecological balance

• Prized for its ornamental value due to its large, glossy leaves and attractive spadix
• Often used in tropical gardens, indoor spaces with high humidity, or as a statement plant in shaded outdoor areas

Wild Population Status

• Not listed as endangered
• Potentially vulnerable to habitat destruction due to deforestation in its native range
• Conservation efforts to protect tropical rainforests are important for the species' long-term survival

Market Availability

• Relatively rare in cultivation but can be found through specialty nurseries or among aroid collectors
• Not widely available in general plant markets
