Anthurium horridum Croat

• Genus: Anthurium
• Botanical Background: Described by Thomas Croat; Contributed to the understanding of morphological diversity in tropical aroids. Its discovery has aided research on evolutionary adaptations within the genus.

• Geographical Range: Indigenous to tropical rainforests in South America
• Environment: Thrives in warm, humid conditions with well-draining, organic soils. It naturally grows in shaded forest understories where filtered light, consistent moisture, and high humidity create optimal conditions for its development.

Leaves

• Broadly ovate to heart-shaped
• Distinctive rough or textured surface that contrasts with the glossy appearance of many aroids
• Deep green coloration with prominent venation and subtle patterning

Inflorescence (Spadix & Spathe)

• Consists of a moderately sized spathe that typically shows pale hues such as cream or light green
• Slender spadix that, while emitting a mild scent, is primarily structured to attract specific pollinators

Growth Habit

• Grows as a terrestrial plant from a creeping rhizome
• Forms clumps on the forest floor and may occasionally exhibit epiphytic tendencies by colonizing decaying wood in its natural environment.

Light Requirements

• Bright; indirect light
• Avoid direct sunlight to prevent leaf burn

Watering & Humidity

• Keep the soil consistently moist while ensuring excellent drainage
• High humidity is essential
• Regular misting or using a humidifier can help replicate its natural conditions

Soil & Potting Mix

• A well-draining, organic-rich potting mix is recommended
• Blend of peat, orchid bark, and perlite will simulate the loose, fertile substrate of its native habitat

Temperature & Fertilizer

• Maintain temperatures between 65°F and 80°F
• Balanced liquid fertilizer applied every few weeks

Division

• Rhizome division
• Division should include at least one active growth node to ensure successful establishment

Seeds

• Less common due to slower germination
• Should be done under controlled conditions with stable warmth and high humidity

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering can lead to root rot and fungal infections; thus, proper drainage is vital

Treatment Recommendations

• Organic pest control measures such as neem oil or insecticidal soap are effective
• Adjust watering practices and enhance air circulation to reduce fungal risks
• Use chemical treatments sparingly and only when necessary

• Plays an important role in its ecosystem by attracting specialized pollinators
• Unusual leaf texture has intrigued botanists and added value to studies on aroid diversity

• Rare, textured foliage and elegant inflorescenc
• Unique aesthetic and limited availability make it a standout plant in curated tropical collections

Wild Population Status

• Detailed population data is limited
• Increasingly threatened by deforestation and habitat fragmentation
• Conservation efforts aimed at preserving tropical rainforests are essential for its survival

Market Availability

• Considered rare in cultivation
• Specialized requirements and limited natural distribution contribute to its high demand among dedicated aroid collectors
