Anthurium circinatum Croat

• Genus: Anthurium
• Botanical Background: Named by botanist Thomas B. Croat in 1983, Anthurium circinatum is a relatively recent addition to the genus and has sparked interest among plant enthusiasts due to its distinctiveness in form and appearance.

• Geographical Range: Found in the tropical regions of Panama and Costa Rica, specifically in lowland rainforests and humid montane forests at elevations between 600–1,500 meters.
• Environment: Thrives in warm, humid conditions with well-drained, slightly acidic soils. Naturally grows in shaded understory areas where moisture is consistently high.

Leaves

• Narrow and elongated, with a characteristic lanceolate shape
• Dark green, leathery
• Can reach up to 30 cm in length, providing a glossy finish

Inflorescence (Spadix & Spathe)

• The spathe is typically a creamy white or pale green, surrounding a yellowish spadix
• Emits a mild, pleasant fragrance
• Pollinated by small insects that are attracted to the subtle scent

Growth Habit

• Terrestrial, growing close to the ground
• Has a creeping habit with a fibrous root system, and does not form large rhizomes like some other Aroids

Light Requirements

• Prefers bright, indirect light, as direct sunlight may scorch its leaves
• Can tolerate some lower light conditions but thrives in dappled light

Watering & Humidity

• Regular watering is essential, ensuring the soil remains consistently moist but not waterlogged
• High humidity (60–80%) is necessary for optimal growth

Soil & Potting Mix

• A well-draining, rich, organic potting mix works best
• A mix containing peat, perlite, and pine bark is ideal for simulating its native habitat

Temperature & Fertilizer

• Ideal temperatures range between 18–24°C (65–75°F)
• Fertilizing once a month with a balanced, diluted fertilizer during the growing season supports healthy growth

Division

• Most commonly done through division of clumps

Stem Cuttings (if applicable)

• Done by taking cuttings of stem sections that include a node and aerial roots

Seeds

• Can be propagated from seeds, the process is slower and requires patience
• Should be sown in a humid environment and kept at a consistent warm temperature for successful germination

Typical Issues

• Common pests include aphids, scale, and mealybugs
• Root rot can also occur if the plant is overwatered or planted in poorly-draining soil

Treatment Recommendations

• Use insecticidal soap or neem oil for pest control
• Ensure proper drainage to prevent root rot
• Regular inspection of leaves and stems helps catch issues early
  

• Often admired for its ability to add architectural beauty to indoor spaces
• In some cultures, it is seen as a symbol of longevity due to its hardy growth

• Prized for its compact, elegant growth and glossy, dark green leaves
• Often used in tropical plant collections or as an ornamental indoor plant

Wild Population Status

• Currently, not listed as endangered but is still relatively rare in the wild. Its natural habitat is subject to deforestation and habitat loss

Market Availability

• Moderately available in the plant trade
• Can be considered a more specialized or rare find in many regions due to its specific care requirements
