Anthurium cobbiae Croat & Delannay

• Genus: Anthurium
• Botanical Background: Named by botanists Croat and Delannay in 1980, Anthurium cobbiae is named after the area where it was first discovered. Its botanical classification has remained stable within the Anthurium genus.

• Geographical Range: Native to the tropical rainforests of Central America, particularly in Costa Rica and Panama; it is found at low to mid-elevations in humid, shaded environments.
• Environment: Thrives in moist, shaded areas with high humidity and well-draining soils; it naturally grows under the canopy of tropical forests, where it receives filtered light and consistent moisture.

Leaves

• Large, leathery, and heart-shaped
• Glossy, dark green surface
• The leaf blades can reach up to 30 cm long and 20 cm wide, with a smooth texture and prominent veins

Inflorescence (Spadix & Spathe)

• The spadix of is creamy white, surrounded by a spathe that is typically greenish in color
• The spadix can reach up to 15 cm in length
• Pollination is likely insect-mediated, with bees or other small insects attracted to its subtle scent
  

Growth Habit

• An epiphytic plant, meaning it grows on trees or other structures rather than in the ground
• It is not a climbing species and does not have tubers, instead relying on its rhizome for reproduction

Light Requirements

• Prefers bright, indirect light; will thrive in environments where it is shielded from direct sunlight
• Direct sunlight should be avoided to prevent leaf burn

Watering & Humidity

• Regular watering is essential to maintain evenly moist soil
• High humidity is beneficial; humidity level of 60% or higher
• Avoid waterlogging to prevent root rot

Soil & Potting Mix

• A well-draining, aerated potting mix that retains moisture
• A mix designed for orchids or aroids, with components like perlite, orchid bark, and sphagnum moss, works well

Temperature & Fertilizer

• Between 65°F and 80°F
• Balanced water-soluble fertilizer monthly diluted to half strength

Seeds

• Less commonly done due to the slow germination process and specific conditions required for seedling survival

Typical Issues

• Spider mites, aphids and mealybugs
• Root rot can occur if overwatered

Treatment Recommendations

• For pest control, insecticidal soap or neem oil is effective against most common pests
• To prevent root rot, ensure the potting mix is well-draining and avoid standing water

• Primarily grown for its ornamental value
• Its lush foliage and unique appearance make it a popular choice for interior decoration

• Highly prized for its dramatic, glossy leaves and distinct, elegant inflorescences
• It is often used as a decorative houseplant in tropical and subtropical regions
  

Wild Population Status

• While not critically endangered, Anthurium cobbiae faces habitat loss due to deforestation in its native regions
• Conservation efforts are in place to protect its natural habitats
  

Market Availability

• Relatively rare in cultivation
• Occasionally available in specialty nurseries that focus on rare aroids
