Anthurium arandae Croat & O.Ortiz

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat and O.Ortiz, this species has been studied within the context of South American aroid diversity. Its formal description has contributed to a better understanding of the evolutionary relationships within Anthurium

• Geographical Range: Native to tropical regions in South America, with populations reported in areas featuring humid, lowland forests and montane regions.
• Environment: This species thrives in warm, humid conditions with well-drained, organic-rich soils. It typically grows in shaded forest understories where consistent moisture and moderate temperatures are the norm

Leaves

• Broad,  heart-shaped leaves
• Leathery in texture
• Exhibit a deep green coloration

Inflorescence (Spadix & Spathe)

• Vibrant spathe
• Central spadix
• Scent is generally mild or absent

Growth Habit

• Terrestrial

• Develops from a rhizomatous root system that supports its upright growth

• Does not typically form aerial tubers

Light Requirements

• Bright, indirect light
• Too much direct sunlight may scorch the leaves, while low light can hinder growth

Watering & Humidity

• Regular watering to maintain consistently moist soil is essential
• High humidity levels help prevent leaf desiccation, especially in indoor environments

Soil & Potting Mix

• A well-draining mix rich in organic matter is recommended
• A combination of peat, perlite, and orchid bark works well to mimic its natural forest floor conditions

Temperature & Fertilizer

• Ideal temperatures range from 65°F to 80°F (18°C to 27°C)

• Balanced, diluted fertilizer applied monthly during the growing season can support healthy development

Division & Cutting

• Propagation is most successful through careful division of the rhizome. Ensure that each division has at least one growing point to encourage successful reestablishment

Seeds

• While seed propagation is possible, it is less common due to variable germination rates and the longer time required to reach maturity

Typical Issues

• Spider mites and mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Treatment involves regular monitoring and the use of organic insecticidal soap for pests
• Ensuring proper drainage and avoiding overwatering are key to preventing fungal issues
  

• The species has captured the interest of botanists and collectors alike. Its discovery has enriched our understanding of South American aroid diversity and ecological interactions

• Enthusiasts prize Anthurium arandae for its rare occurrence and the dramatic contrast between its dark foliage and vivid inflorescence, making it a coveted specimen for tropical plant collections

Wild Population Status

• No critical conservation concerns have been widely reported; however, habitat loss in tropical regions underscores the importance of continued field research and preservation efforts

Market Availability

• It is considered relatively rare in cultivation. Collectors may find it only through specialized nurseries or botanical exchanges
