Anthurium aroense G.S.Bunting

• Genus: Anthurium
• Botanical Background: Described by G.S. Bunting, Anthurium aroense has intrigued botanists due to its unique morphology and adaptation to humid tropical habitats. Its classification reflects decades of study in neotropical flora.

• Geographical Range: Native to neotropical regions
• Environment: Naturally grows in warm, humid conditions with dappled light, preferring well-draining, organically rich soils typical of rainforest floor environments.

Leaves

• Boasts moderately sized
• Glossy leaves
• Heart-shaped or elongated with prominent venation
• Deep green color

Inflorescence (Spadix & Spathe)

• Vibrant spathe that may display hues ranging from green to red, encircling a slender spadix
• Structure is adapted for specialized pollinators, although it is not known for a strong scent

Growth Habit

• Terrestrial plant with a clumping habit, emerging from thick rhizomes that facilitate its steady spread

Light Requirements

• Bright, indirect light to mimic its natural forest understory

Watering & Humidity

• Maintain consistently high humidity and water moderately
• Ensuring the soil remains moist but never waterlogged

Soil & Potting Mix

• A loose, well-draining mix rich in organic matter is ideal
• Incorporating bark or perlite can enhance drainage in a standard potting mix

Temperature & Fertilizer

• Keep the temperature warm, ideally between 65°F and 80°F (18°C–27°C)

• Use a balanced, water-soluble fertilizer monthly during the growing season

Division & Cutting

• Most common propagation method is by division of the rhizome during repotting, ensuring each section has healthy roots and shoots

Seeds

• Less common due to variable germination rates, maintaining a warm, humid environment can improve success when seed propagation is attempted

Typical Issues

• Spider mites, mealybugs and scale insects
• Fungal issues and root rot

Treatment Recommendations

• Employ integrated pest management strategies using organic insecticidal soap
• Ensure proper airflow around the plant
• For fungal problems, adjust watering practices and use appropriate fungicides if necessary

• Prized for its rarity and the unique combination of ornamental foliage with a striking inflorescence. 

• Presence in a collection often signifies a refined taste for exotic tropical species

• Valued for its decorative appeal and serves as an excellent specimen plant in indoor tropical gardens and conservatories

Wild Population Status

• Natural populations may be sensitive to habitat loss due to its specialized habitat

• Conservation efforts are important to protect its rainforest environment

Market Availability

• Relatively rare in cultivation, making it a sought-after species among collectors and enthusiasts
