Anthurium polancoi Croat

• Genus: Anthurium
• Botanical Background: Described by renowned botanist Thomas B. Croat, an authority in Araceae studies. Its discovery contributed to a broader understanding of the diversity within tropical aroid species.

• Geographical Range: Indigenous to the Andean regions of tropical South America, with occurrences noted in Colombia and Ecuador.
• Environment: Prefers rich, organically dense soils with excellent drainage. Flourishes under a stable tropical climate with high humidity and moderate temperatures. 

Leaves

• Broad and glossy with prominent venation
• Typically heart-shaped with slight lobing along the margins
• Medium to large in size, displaying a smooth, leathery texture

Inflorescence (Spadix & Spathe)

• Spathe exhibits a muted, often greenish tone that contrasts with the spadix
• Spadix supports numerous small flowers arranged compactly
• May emit a subtle fragrance to attract specialized pollinators

Growth Habit

• Terrestrial; can also adopt an epiphytic habit in its native habitat
• Develops a robust, rhizomatous root system

Light Requirements

• Bright, indirect light to maintain vibrant foliage
• Tolerates partial shade, which mimics its natural forest understory
• Avoid direct, intense sunlight that can scorch leaves

Watering & Humidity

• Requires regular watering with allowances for slight drying between sessions
• Thrives in consistently high humidity, replicating tropical conditions

Soil & Potting Mix

• A well-aerated, lightweight aroid-specific potting mix (perlite or orchid bark)
• Containers should allow for adequate drainage to avoid waterlogging

Temperature & Fertilizer

• Optimal temperature range is between 65°F and 80°F
• Balanced liquid fertilizer every 4–6 weeks during active growth

Division

• Dividing the rhizomes during repotting is the most common

Stem Cuttings (if applicable)

• Less common for this species
• When attempted, success requires careful moisture control and high humidity
  

Seeds

• Rarely used due to slow and unpredictable germination
• May require specific stratification or pre-treatment to enhance viability

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if overwatered or kept in poorly draining soil

Treatment Recommendations

• Insecticidal soap can be effective against spider mites and mealybugs
• Improve air circulation and adjust watering practices to manage rot and fungal issues

• Its rare appearance in the wild adds an element of mystique among tropical plant enthusiasts
• The species is named in honor of an individual or collector, reflecting its unique discovery history

• Valued for its dramatic, sculptural leaf form that enhances any collection
• The subtle yet elegant inflorescence adds to its ornamental allure

Wild Population Status

• Wild populations may be limited and face threats from habitat destruction

Market Availability

• Typically rare in cultivation and may be difficult to source outside specialized collections
• Availability is generally restricted to advanced collectors and botanical enthusiasts
