Anthurium gelpii Croat

• Genus: Anthurium
• Botanical Background: Anthurium gelpii was described by botanist Thomas Croat, who has made significant contributions to the classification of tropical aroids. The species is named in honor of its discovery in the Gelpi region, a region known for its biodiversity in Central America.

• Geographical Range: Found in the lowland and montane rainforests of Costa Rica and Panama
• Environment: Prefers high humidity (60–80%), typical of rainforest ecosystems, Grows best in well-draining, organic-rich soils that retain moisture without becoming waterlogged, Thrives in temperatures between 20°C and 28°C (68°F to 82°F), with consistent rainfall year-round.

Leaves

• Large, heart-shaped leaves with a glossy, leathery texture
• Leaves are dark green and can grow up to 40 cm in length, with prominent veins and a smooth, glossy surface that enhances their ornamental appeal

Inflorescence (Spadix & Spathe)

• Spadix is white and cylindrical, rising from a pale green spathe
• Spathe is typically arching, providing contrast to the white spadix
• Inflorescence has no strong scent but attracts pollinators through its visual appeal

Growth Habit

• Terrestrial species, growing from a rhizome. It has a compact, bushy growth habit and can reach up to 40–50 cm (16–20 inches) in height, making it ideal for container cultivation or smaller garden spaces

Light Requirements

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

Watering & Humidity

• Keep the soil evenly moist but ensure it drains well. Water when the top layer of soil begins to dry out
• Requires high humidity, around 60–80%. A humidity tray or regular misting can help maintain optimal moisture levels

Soil & Potting Mix

• A well-draining, organic-rich potting mix is recommended. A combination of peat, perlite, and pine bark works well to retain moisture while ensuring good drainage

Temperature & Fertilizer

• Ideal temperatures range from 20°C to 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 growth slows

Division

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

Seeds

• Seed propagation is possible but not commonly used for Anthurium gelpii
• Seeds require a warm and humid environment to germinate, and this process can take several months
  

Typical Issues

• Aphids, mealybugs, and spider mites
• Overwatering can lead to root rot, while fungal infections such as powdery mildew may occur 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 good airflow to reduce fungal growth and avoid excess moisture on the leaves

• Ccontributes to the biodiversity of the rainforests of Central America, where it supports pollinators such as beetles and other small insect
• Often found in shaded areas of the rainforest, thriving in the humid conditions of its native environment

• Glossy, heart-shaped leaves and attractive spadix, Anthurium gelpii is highly prized for its ornamental value
• Particularly suitable for small gardens, container cultivation, or as an indoor plant in tropical and subtropical climates

Wild Population Status

• Not listed as endangered
• Habitat destruction due to deforestation could impact its populations in the wild
• Conservation of its natural rainforest habitats is essential for its continued survival
  

Market Availability

• Rare in cultivation but can be found through specialty nurseries and among collectors of rare aroids
• Not widely available in mainstream garden centers
