Anthurium gentryi Croat

• Genus: Anthurium
• Botanical Background: First described by botanist Thomas Croat, Anthurium gentryi was named after the botanist and ecologist, Robert Gentry, who made significant contributions to the understanding of Central American flora. Croat’s work on the genus Anthurium has added numerous species to the scientific community’s knowledge.

• Geographical Range: Found primarily in the tropical rainforests of Panama and Costa Rica,
• Environment: Prefers high humidity, typical of tropical rainforest ecosystems (60–80%), Grows in well-draining, organic-rich soils that retain moisture but avoid waterlogging, Ideal for tropical climates with consistent temperatures ranging from 20°C to 28°C (68°F to 82°F), with regular rainfall throughout the year.

Leaves

• Large, heart-shaped leaves that are dark green and leathery in texture
• Can grow up to 40 cm (16 inches) long with prominent veins, giving them a distinctive appearance

Inflorescence (Spadix & Spathe)

• Spadix is white and cylindrical, rising from a pale green spathe
• Inflorescence is not strongly fragrant but is visually attractive, with a unique contrast between the white spadix and green spathe
• Pollinated by small insects attracted to the spadix

Growth Habit

• Terrestrial species that grows from a rhizome. It has an upright, bushy growth habit and typically reaches a height of 40–50 cm (16–20 inches), making it ideal for small spaces or container cultivation

Light Requirements

• Prefers bright, indirect light but can tolerate moderate shade
• Avoid direct sunlight, as it can scorch the leaves

Watering & Humidity

• Keep the soil evenly moist but well-drained. Water when the top layer of soil starts to dry out
• High humidity (60%–80%) is essential. Misting the plant or using a humidity tray will help maintain optimal moisture levels

Soil & Potting Mix

• A well-draining, organic-rich potting mix is ideal. A combination of peat, perlite, and pine bark ensures that the soil retains moisture without becoming waterlogged

Temperature & Fertilizer

• Grows best in temperatures between 20°C and 28°C (68°F to 82°F). Avoid exposure to cold drafts and temperatures below 18°C (64°F)
• Apply a balanced liquid fertilizer once a month during the growing season
• Reduce feeding during the cooler months when growth slows
  

Division

• Propagation is typically done by rhizome division
• Ensure each division has healthy roots and at least one leaf to promote regrowth
  

Seeds

• Seed propagation is possible but not commonly used
• Seeds need warm, humid conditions for successful germination, and it may take several months for germination
  

Typical Issues

• Mealybugs, spider mites, aphids, and scale insects
• Overwatering can lead to root rot, and fungal diseases like powdery mildew can develop in overly humid conditions

Treatment Recommendations

• Use insecticidal soap or neem oil to treat pest infestations
• For organic pest control, wash pests off with a mixture of water and mild dish soap
• Ensure good airflow to reduce fungal growth and avoid excessive moisture on the plant
  

• Part of the diverse plant life in Central American rainforests and plays an important role in supporting local pollinators, including insects
• Named in honor of Robert Gentry, a botanist renowned for his contributions to the study of tropical plants

• Prized for its ornamental value. The glossy, heart-shaped leaves and striking white spadix make it a favorite among collectors
• Well-suited for tropical gardens, indoor spaces with high humidity, or as an accent plant in shaded outdoor areas

Wild Population Status

• Not listed as endangered
• Habitat destruction due to deforestation in Central America may threaten its wild populations
• Conservation efforts focused on preserving rainforests are important for its continued survival

Market Availability

• Relatively rare in cultivation but can be found through specialty nurseries or among aroid collectors
• Not commonly found in mainstream plant markets
