Anthurium sixaolense Croat, Belt & O.Ortiz

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat, Belt, and O. Ortiz, this species adds to the diverse and complex taxonomy of Anthurium. Its discovery has helped expand the understanding of aroid diversity in Central America

• Geographical Range: Native to the tropical regions of Central America, particularly in areas that include the Sixaola region
• Environment: Naturally grows in warm, humid conditions with well-draining soils found in tropical rainforests. Its habitat is characterized by consistent moisture and filtered light beneath the forest canopy

Leaves

• Heart-shaped to lanceolate
• Medium to large in size
• Glossy texture
• Rich dark green color
• Smooth surface and defined venation

Inflorescence (Spadix & Spathe)

• Contrasting spathe that may display hues of red or pink against a central spadix
• Not notably fragrant, visual impact plays a role in attracting specialized pollinators

Growth Habit

• Exhibits a terrestrial habit, growing in clumps within organic-rich, well-draining substrates
• Epiphytic tendencies, most often found rooted in the forest floor

Light Requirements

• Bright, indirect light or partial shade, which mimics its natural understory habitat

Watering & Humidity

• Regular watering is important to maintain moist conditions
• High humidity is preferred
• Care should be taken to avoid waterlogging

Soil & Potting Mix

• A well-aerated, organic-rich potting mix with ample drainage is ideal 
• Containers that allow for good water runoff will help maintain healthy root systems 

Temperature & Fertilizer

• Maintain an environment with temperatures between 65°F and 80°F
• Balanced liquid fertilizer applied monthly during the growing season supports optimal growth

Division and Cuttings

• Most effectively achieved through the division of established clumps
• Careful separation of rhizomes or root segments ensures new plants develop successfully

Seeds

• Less commonly practiced due to the species’ slow and variable germination 
• Controlled environments can improve success rates for seed-grown specimens

Typical Issues

• Spider mites and mealybugs
• Fungal issues like root rot

Treatment Recommendations

• Use of organic insecticidal soaps or mild systemic treatments
• Ensuring proper drainage and avoiding overwatering

• Species name reflects its connection to the Sixaola region
• Ecological role in its native habitat includes interactions with specialized pollinators and contributions to forest biodiversity
• Collectors value Anthurium sixaolense for its unusual leaf shape and vibrant inflorescence

Wild Population Status

• Limited, habitat preservation in Central American rainforests remains critical to the species’ continued survival.

Market Availability

• Relatively rare in cultivation
• Generally available only through specialist nurseries or botanical collections, adding to its allure among enthusiasts
