Anthurium paulmaasii Croat

• Genus: Anthurium
• Botanical Background: Described by renowned botanist Thomas B. Croat and is named in honor of Paul Maas, whose pioneering work in tropical botany has significantly contributed to our understanding of aroids.

• Geographical Range: Indigenous to the tropical lowland and premontane rainforests of South America, likely along the Andean foothills.
• Environment: Thrives in consistently warm, humid conditions with moderate to heavy rainfall. The species prefers well-draining, organic-rich soils typical of forest floors, ensuring both moisture retention and root aeration.

Leaves

• Glossy, heart-shaped to elliptical leaves
• Firm, leathery texture and subtle venation
• Deep green coloration, sometimes accented with hints of variegation

Inflorescence (Spadix & Spathe)

• Contrasting spathe and spadix arrangement
• Flowers are not notably fragrant, their vibrant colors and distinct structure are adapted for specialized pollinators

Growth Habit

• Typically terrestrial; grows as clumps emerging from creeping rhizomes
• Growth pattern makes it manageable in cultivated settings while reflecting its natural clustering habit

Light Requirements

• Bright, indirect light
• Excessive direct sunlight may cause leaf scorch, so filtered or diffused lighting is ideal

Watering & Humidity

• Regular watering is essential to maintain consistently moist soil, especially during warmer periods
• High ambient humidity, as found in its native habitat, supports optimal growth

Soil & Potting Mix

• A loose, well-draining potting mix enriched with organic material mimics its natural forest floor conditions
• Container choices should promote aeration and proper drainage

Temperature & Fertilizer

• Ideal temperatures range from 65–80°F (18–27°C)
• A balanced, diluted fertilizer applied on a monthly basis during the growing season helps sustain healthy development

Division and Cuttings

• Preferred propagation technique is the division of rhizomes during repotting

Seeds

• Less common due to slower germination rates and the challenges in replicating the species’ native microclimate in cultivation

Typical Issues

• Spider mites or mealybugs
• Root rot can also occur if watering practices are too liberal

Treatment Recommendations

• Integrated pest management using insecticidal soap is typically effective against insect pests
• Ensuring proper drainage and using organic fungicides in cases of minor infections is recommended

• Not only a subject of botanical interest but also a living testament to the rich biodiversity of tropical rainforests
• Commemorates Paul Maas, an influential figure in the study of aroids

• Prized for its striking leaf form and rare inflorescence
• Unusual appearance makes it a standout plant in specialized tropical collections

Wild Population Status

• Faces pressures from habitat disruption due to its limited range and specific habitat requirements

Market Availability

• Available through specialty nurseries and reputable collectors rather than mainstream plant retailer
