• Genus: Anthurium
• Botanical Background: Described by botanist Thomas B. Croat in 1979. It was named to honor the unique characteristics that distinguish it from other species within the genus.

• Geographical Range: Native to tropical regions of Central America, particularly in Costa Rica and Panama.
• Environment: Thrives in humid, tropical environments with moderate rainfall and temperatures; It is commonly found in shaded forest areas, often growing near streams or moist soil.

Leaves

• Large, leathery
• Glossy with a deep green color
• Broadly ovate to cordate
• Pronounced venation

Inflorescence (Spadix & Spathe)

• Spadix is slender and yellow, surrounded by a greenish spathe
• Not strongly scented
• Pollinated by insects, likely those attracted to the color contrast

Growth Habit

• Terrestrial plant, typically growing from the ground, with no climbing behavior
• Develops from a rhizomatic root system and forms dense clumps

Light Requirements

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

Watering & Humidity

• Keep the soil consistently moist with excellent drainage to avoid waterlogging
• High humidity (60%-70%) is crucial

Soil & Potting Mix

• A well-draining, loamy mix with added organic matter is best
• A mix of peat, perlite, and pine bark is recommended for optimal growth

Temperature & Fertilizer

• Ideal temperatures between 65°F and 80°F (18°C to 27°C)
• Balanced liquid fertilizer diluted to half strength monthly

Division and Cuttings

• Division of the rhizomes
• Stem cuttings with a node can also be rooted in water or soil

Seeds

• Less common, requiring high humidity and temperature to encourage germination

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering can lead to root rot or fungal infections
• Proper drainage and careful watering are essential

Treatment Recommendations

• Organic treatments like neem oil or insecticidal soap are effective for controlling pest infestations
• Adjust watering practices and improve air circulation to prevent fungal issue
• Use chemical treatments sparingly when necessary

• Named after Dr. Luther, who contributed significantly to the study of Central American flora
• Appreciated by enthusiasts for its unique leaf structure

• Prized for its large, glossy foliage
• An attractive plant for tropical gardens or indoor collections in humid environments

Wild Population Status

• No immediate conservation concerns
• Habitat loss in Central America may affect its natural populations over time

Market Availability

• Relatively uncommon in commercial markets 
• Primarily available through specialized Aroid collectors
