Anthurium hieronymi Engl.

• Genus: Anthurium
• Botanical Background: Described by Adolf Engler; Contributed to the expanding understanding of tropical aroid diversity; Formal classification has been important in elucidating evolutionary relationships within the genus.

• Geographical Range: Indigenous to tropical rainforests in South America
• Environment: Thrives in warm, humid conditions with well-draining, organic soils; Low-light environment of forest understories, where high humidity and regular rainfall support its growth

Leaves

• Elegant and broadly ovate with a smooth, glossy texture
• Deep green coloration with distinct venation that enhances their ornamental appeal

Inflorescence (Spadix & Spathe)

• Features a moderately sized spathe, often displaying light hues such as cream or pale green, which encloses a slender spadix
• Scent is generally subtle
•  Floral structure is key to attracting its natural pollinators

Growth Habit

• Grows from a creeping rhizome that enables clumping
• Exhibit epiphytic tendencies, growing on decaying wood within the forest understory

Light Requirements

• Bright; indirect light
• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Keep the soil consistently moist with good drainage
• High ambient humidity is essential
• Regular misting or a humidifier is recommended, especially in indoor environments

Soil & Potting Mix

• A well-draining mix enriched with organic matter is ideal
• Peat, orchid bark, and perlite closely mimics the natural forest floor substrate and ensures adequate moisture retention

Temperature & Fertilizer

• Maintain temperatures between 65°F and 80°F
• Balanced liquid fertilizer every three to four weeks

Division

• Most commonly achieved through rhizome division
• Each division should include an active growth node to ensure successful establishment

Seeds

• Less common; Can be attempted in controlled environments that maintain high humidity and stable warmth to encourage germination

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering can lead to root rot and fungal infections, so careful monitoring of soil moisture is critical

Treatment Recommendations

• Organic treatments such as neem oil or insecticidal soap are effective for pest contro
• For fungal issues, adjust watering practices and improve air circulation around the plant
• Chemical treatments should be used as a last resort
  

• Plays an important role in its native ecosystem by supporting specialized pollinators
• Unique leaf structure and subtle inflorescence have made it a subject of interest in botanical research

• Refined foliage and elegant floral display
• Rarity in cultivation and striking appearance make it a standout addition to any tropical plant collection

Wild Population Status

• Comprehensive population data may be limited
• Increasingly threatened by deforestation and habitat loss
• Conservation initiatives focused on rainforest preservation are critical
  

Market Availability

• Considered rare in cultivation
• Specialized growth requirements and limited natural distribution contribute to its status as a prized find among aroid collectors
