Anthurium antisanense Croat & R.Zambrano

• Genus: Anthurium
• Botanical Background: The species was described by noted botanists Croat and R. Zambrano, who have made significant contributions to the study and classification of aroids.

• Geographical Range: Indigenous to the Andean regions, where it is typically found in humid, high-altitude forests.
• Environment: Thrives in shaded understory settings with high humidity, well-draining, organically rich soils, and moderate temperature ranges typical of montane climates.

Leaves

• Generally large heart-shaped leaves
• Glossy texture
• Deep green coloration
• Occasional subtle variegation or mottling

Inflorescence (Spadix & Spathe)

• Colorful spathe and a compact spadix
• Spathe may display soft contrasts in color
•  Generally attracts specific pollinators without emitting a strong scent

Growth Habit

• Typically terrestrial

• Develops a spreading habit with a robust rhizome system that supports its growth in dense forest understories

Light Requirements

• Bright, indirect light to mimic its natural forest understory environment

Watering & Humidity

• Keep the soil consistently moist without waterlogging 
• High humidity levels for optimal growth

Soil & Potting Mix

• Use a well-draining mix enriched with organic matter
• Loose, airy medium in a container with drainage holes is idea

Temperature & Fertilizer

• Ideal temperature range is between 65°F and 80°F

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

Division & Cutting

• Most effective propagation method is through division of the rhizome

• Divide the plant during repotting, ensuring each section includes sufficient roots

Seeds

• Low germination rates and a longer period required to reach maturity

Typical Issues

• Spider mites and mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Apply insecticidal soap for pest control
• Adjust watering practices to improve soil drainage
• Organic remedies may also be effective in preventing and treating infestations

• Valued for rare and intriguing morphology, which highlights the diversity of tropical plants

• Unusual leaf structure and vibrant inflorescence

• Prized addition to specialized collections and botanical display

Wild Population Status

• Limited natural range

• May be subject to conservation concerns

• Efforts to protect its natural habitat are important for its long-term survival

Market Availability

• Generally rare in the commercial nursery trade

• Mainly available through specialized collectors or botanical exchanges
