Anthurium annularum O.Ortiz, Croat & Baldini

• Genus: Anthurium
• Botanical Background: The species was described by botanists O.Ortiz, Croat, and Baldini, whose work has helped refine the modern understanding of Anthurium taxonomy.

• Geographical Range: Native to the Andean regions, likely within parts of Colombia.
• Environment: Flourishes under conditions of high humidity, shaded light typical of forest understories, and well-draining, organic-rich soils in consistently warm climates.

Leaves

• Dark green
• Heart-shaped leaves
• Glossy texture and annular patterns

Inflorescence (Spadix & Spathe)

• Compact spadix encircled by a vibrant spathe
• Inflorescence not only enhances its decorative value but also plays a key role in attracting insect pollinators

Growth Habit

• Generally terrestrial

• Develops a rhizomatous growth habit that forms compact clumps, supporting its overall structure

Light Requirements

• Bright, indirect light, mimicking its natural understory conditions

Watering & Humidity

• Requires consistent moisture with 
• High ambient humidity
• Water regularly while allowing the top layer of soil to dry slightly between sessions

Soil & Potting Mix

• A well-draining potting mix enriched with organic matter; containers should allow ample room for rhizome expansion

Temperature & Fertilizer

• Enjoys warm, tropical temperatures

• Balanced fertilizer during the active growing season

Division & Cutting

• Most common propagation method is rhizome division, ensuring each segment has sufficient roots and shoots for successful growth

Seeds

• Less favored due to variable germination rates and longer maturation periods

Typical Issues

• Spider mites and aphids
• Fungal issues and root rot

Treatment Recommendations

• Implement insecticidal soap treatments for pest control

• Adjust watering practices to prevent fungal infections and maintain plant health

• Unique annular leaf markings have intrigued botanists and collectors, highlighting its role in studies of Anthurium diversity

• Prized for its ornamental inflorescence and distinctive leaf design, making it a coveted addition to specialized tropical plant collections

Wild Population Status

• Data on wild populations is limited, indicating a need for further study and potential conservation efforts

Market Availability

• Not commonly found in mainstream horticulture

• Available through specialist collectors and niche botanical markets
