Anthurium obtusifolium (W.T.Aiton) G.Don

• Genus: Anthurium
• Botanical Background: First described by W.T.Aiton and later classified by G.Don, its discovery is tied to early botanical explorations in tropical regions. Historically studied by noted botanists, it continues to interest researchers due to its classic aroid characteristics.

• Geographical Range: Indigenous to tropical lowland rainforests, the species is found across parts of Central America and the Caribbean.
• Environment: Prefers well-draining, organic-rich soils and consistently high humidity. Naturally thrives in warm, humid climates with filtered sunlight under the rainforest canopy.

Leaves

• Large, broad, and obovate with a glossy finish
• Deep green coloration with prominent, subtle venation
• Variable in size, often exceeding 20 cm in length

Inflorescence (Spadix & Spathe)

• Spathe displays a muted greenish to slightly purplish hue
• Slender spadix supports a ring of inconspicuous flowers
• Overall inflorescence is understated

Growth Habit

• Primarily terrestrial, forming clumps in its natural habitat
• Exhibits a rhizomatous growth habit that supports clonal propagation

Light Requirements

• Bright, indirect light to maintain its leaf coloration
• Can tolerate lower light levels, though growth may be slower
  
• Avoid direct, intense sunlight that can scorch leaves

Watering & Humidity

• Benefits from regular watering to keep the soil evenly moist
• Thrives in high humidity; occasional misting can be beneficial

Soil & Potting Mix

• Flourishes in a well-draining, peat-based mix 
• Mix that mimics its native forest floor, rich in decaying material, is ideal
• Suitable for indoor cultivation in containers with ample drainage

Temperature & Fertilizer

• Optimal growth occurs between 65°F and 80°F (18°C–27°C)
• Balanced liquid fertilizer applied during the growing season
• Avoid exposure to temperatures below 55°F (13°C)
  

Division

• Most common propagation method is through division during repotting
• Each division should include several healthy roots for successful establishment
  

Stem Cuttings (if applicable)

• Rarely practiced due to the plant’s growth habit

Seeds

• Can be sown under sterile conditions but germination may be slow
• Requires consistent moisture and controlled temperatures
  

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if overwatered or kept in poorly draining soil

Treatment Recommendations

• Insecticidal soap or neem oil can effectively control pest infestations
• Improve environmental conditions to combat early signs of fungal problems

• The species is admired for its unique, broad leaves and understated inflorescence
• Frequently featured in botanical collections for its classic tropical appearance

• Prized by plant enthusiasts for its elegant foliage and manageable care requirements
• Versatile for both indoor display and tropical garden landscapes

Wild Population Status

• Not currently listed as endangered, although habitat loss remains a concern in some regions
• Conservation efforts are in place to protect its natural rainforest habitat

Market Availability

• Generally available through specialty nurseries and botanical garden exchanges
• Considered moderately accessible, with occasional rarer forms sought by collectors
