Anthurium gehrigeri Croat

• Genus: Anthurium
• Botanical Background: This species was described by botanist Thomas Croat, who has made significant contributions to the classification of the Anthurium genus. Anthurium gehrigeri was named in honor of the botanist’s friend, Gehriger, reflecting the plant’s scientific and botanical heritage.

• Geographical Range: Found in the lowland and montane rainforests of Panama
• Environment: Prefers high humidity (60–80%) typical of its native rainforest habitat, Thrives in well-draining, organic-rich soils that retain moisture without becoming waterlogged, Best suited for tropical climates with temperatures ranging from 20°C to 28°C (68°F to 82°F), receiving consistent rainfall throughout the year.

Leaves

• Large, dark green, heart-shaped leaves with a smooth, glossy texture
• Leaves can grow up to 40 cm in length, with prominent veins that create a distinctive appearance

Inflorescence (Spadix & Spathe)

• Sppadix is white and cylindrical, standing upright from a pale green to white spathe
• Inflorescence is visually striking but has no noticeable scent
• Pollinated by small insects attracted to the inflorescence’s shape and colo

Growth Habit

• Terrestrial species that grows from a rhizome. It forms an upright, bushy growth habit and reaches about 50 cm in height. It does not climb or trail and is suitable for small garden spaces or as an indoor plant

Light Requirements

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

Watering & Humidity

• Keep the soil evenly moist but well-drained. Water when the top layer of soil starts to dry out
• Requires high humidity (60% or higher) to thrive. Misting, a humidity tray, or a humidifier can help achieve the necessary moisture levels in drier environments

Soil & Potting Mix

• A well-draining, organic potting mix is recommended. A mixture of peat, perlite, and pine bark ensures that moisture is retained without becoming waterlogged

Temperature & Fertilizer

• Grows best in temperatures between 20°C and 28°C (68°F to 82°F). Avoid 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 the plant is not actively growing

Division

• Propagation is best done through rhizome division
• Each division should have healthy roots and at least one leaf to ensure successful growth
  

Seeds

• Propagation by seed is possible but not commonly used
• Seeds should be kept in a warm, humid environment for germination, which can take several months
  

Typical Issues

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

Treatment Recommendations

• Use insecticidal soap or neem oil to treat pest infestations
• A mixture of water and mild dish soap can be used to wash pests off
• Ensure adequate airflow around the plant and avoid excessive moisture to prevent fungal infections
  

• Plays an ecological role in the tropical rainforests of Panama, supporting pollinators like beetles and other insects
• Species is often found in shaded, humid environments, contributing to the biodiversity of its native region

• Glossy leaves and attractive inflorescence, Anthurium gehrigeri is highly prized for ornamental use
• Especially appreciated for its relatively compact size, making it suitable for indoor environments or small gardens

Wild Population Status

• Not listed as endangered
• Distribution in tropical rainforests makes it vulnerable to habitat loss due to deforestation

Market Availability

• Somewhat rare in cultivation but can be found through specialty nurseries or in the collections of aroid enthusiasts
• Not widely available in general plant markets
