Anthurium holquinianum Croat & D.C.Bay

• Genus: Anthurium
• Botanical Background: Described by botanists Croat and D.C.Bay; Enhanced our understanding of aroid diversity. Its formal classification has contributed to studies on evolutionary adaptations in tropical understory plants.

• Geographical Range: Indigenous to the tropical rainforests of South America
• Environment: Thrives in warm, humid conditions with well-draining, organic-rich soils. It prefers the filtered light of forest understories and benefits from consistent moisture and high ambient humidity.

Leaves

• Broadly ovate or heart-shaped with a glossy finish and deep green coloration
• Exhibit distinctive patterns or prominent venation

Inflorescence (Spadix & Spathe)

• Consists of a moderately sized spathe, usually displaying light hues such as cream or pale green, which encloses a slender spadix
• Fragrance is subtle
• Effectively attracts specialized pollinators

Growth Habit

• Grows from a creeping rhizome that forms clumps on the forest floor
• Epiphytic tendencies by establishing on decaying wood in its natural habitat

Light Requirements

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

Watering & Humidity

• Maintain consistently moist soil with excellent drainage
• High humidity is critical
• Regular misting or placement in a humid environment will help mimic natural conditions

Soil & Potting Mix

• Use a well-draining, organic-rich potting mix such as a blend of peat, orchid bark, and perlite
• Mix closely simulates the loose, fertile substrate found in tropical forest floors

Temperature & Fertilizer

• Keep temperatures between 65°F and 80°F for optimal growth
• Balanced liquid fertilizer every few weeks

Division

• Most commonly achieved through rhizome division
• Division should include at least one active growth node to ensure successful establishment

Seeds

• Less frequently practiced due to slower germination rates
• Can be attempted under controlled conditions with stable warmth and high humidity

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering may result in root rot or fungal infections, so ensuring proper drainage is essential

Treatment Recommendations

• Organic treatments like neem oil or insecticidal soap are effective for pest control
• Adjust watering practices and enhance air circulation to mitigate fungal issues
• Chemical treatments should be used sparingly when necessary

• Plays an important role in its native ecosystem by providing habitat for specialized pollinators
• Distinctive leaf patterns and overall morphology make it an interesting subject for botanical research

• Ornamental glossy foliage and elegant inflorescence
• Rarity and striking appearance make it a prized addition to curated tropical plant collections

Wild Population Status

• Detailed population assessments are limited
• Faces threats from deforestation and habitat fragmentation
• Peservation of tropical rainforests is essential for its continued survival
  

Market Availability

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