Anthurium diversurense Croat

• Genus: Anthurium
• Botanical Background: The species was first described by renowned botanist Thomas B. Croat in 1981. Croat's work in the Anthurium genus has helped expand the understanding of this diverse group, particularly in tropical regions of the Americas

• Geographical Range: Central America
• Environment: This species thrives in humid environments with warm temperatures ranging from 20-30°C (68-86°F). It is typically found in shaded understories with well-draining, rich, organic soils

Leaves

• Large, leathery
• Glossy, with a deep green color
• They can grow up to 50 cm long
• Ovate to heart-shaped form
• The texture is smooth, with prominent veins
  

Inflorescence (Spadix & Spathe)

• The inflorescence consists of a typical Anthurium spadix, which is pale yellow or greenish, surrounded by a greenish spathe. The flowers are not particularly fragrant, and pollination is generally achieved by insect activity, often involving flies

Growth Habit

• This species is terrestrial, growing on the forest floor in its native habitat, and does not typically exhibit climbing behavior. It produces a rhizome from which it sends up new growth

Light Requirements

• Anthurium diversurense prefers bright, indirect light. Direct sunlight may scorch the leaves, so it is best grown under filtered light or in shaded indoor conditions

Watering & Humidity

• Consistently moist soil is essential, but overwatering should be avoided to prevent root rot. 
• It thrives in high humidity, ideally above 60%, which mimics its natural rainforest environment

Soil & Potting Mix

• Use a well-draining potting mix with high organic content, such as a mix designed for tropical plants. 
• A blend of peat, perlite, and pine bark works well. Ensure the container has good drainage to avoid waterlogging

Temperature & Fertilizer

• Maintain a temperature range of 18-26°C (65-79°F)
• During the growing season (spring and summer), fertilize every 4-6 weeks with a balanced liquid fertilizer. Reduce feeding during the dormant period in winter
  

Division and Cuttings

• Propagation is typically done through rhizome division, where sections of the plant with roots are separated and potted individually. Node cuttings can also be used, though they may take longer to root

Seeds

• Propagation by seed is possible but not commonly practiced. Seeds must be sown in a humid, warm environment, and germination may take several weeks

Typical Issues

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

Treatment Recommendations

• Treat pest infestations with insecticidal soap or neem oil. For root rot, ensure proper drainage and avoid overwatering. Fungicide can be applied for fungal infections if necessary

• While Anthurium diversurense does not have specific cultural significance, it is appreciated by collectors due to its rarity and distinct leaf morphology

• This species is prized for its large, attractive leaves and robust growth in tropical and subtropical gardens. It’s ideal for plant enthusiasts looking for a unique addition to their collection

Wild Population Status

• There are no major conservation concerns for Anthurium diversurense; however, habitat loss due to deforestation in Central America may pose a long-term threat

Market Availability

• Anthurium diversurense is considered rare in cultivation, but it can be found in specialty plant shops or among collectors of rare aroids
