• Genus: Anthurium
• Botanical Background: Described by botanist Matuda in the early 20th century; named after its original discovery location, which was along the Lezama River in Costa Rica.

• Geographical Range: Endemic to the cloud forests of Costa Rica and Panama; grows at altitudes ranging from 1,000 to 2,000 meters above sea level.
• Environment: Humid, shaded areas with well-drained soil, thriving in temperatures between 20-25°C (68-77°F); favors areas with high rainfall, typical of tropical rainforests.

Leaves

• Glossy, deep green, and typically large
• Elongated oval shape
• Surface is smooth
• Leathery texture
• Young leaves are often lighter in color, turning darker as they mature

Inflorescence (Spadix & Spathe)

• Spadix is long and cylindrical, featuring a yellowish color when in bloom
• Spathe, or modified leaf, is creamy white and wraps around the spadix
• Scent is subtle

Growth Habit

• Epiphytic plant
• Clinging to tree trunks
• Grows from a rhizome and does not form tubers

Light Requirements

• Bright, indirect
• Direct sunlight can scorch its leaves

Watering & Humidity

• Consistently moist soil
• High humidity levels, ideally above 60%
• Mist the leaves if humidity drops too low

Soil & Potting Mix

• A well-draining, organic-rich potting mix
• A mixture of peat, perlite, and orchid bark 

Temperature & Fertilizer

• Temperatures between 20-25°C (68-77°F)

• Fertilize with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season

Division and Stem Cuttings

• Most effective method of propagation is through rhizome division
• Cuttings can also be taken
• Require a humid environment for successful rooting

Seeds

• Not typically propagated by seeds in cultivation due to the rarity of flowering in non-native environments

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot 

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure proper drainage
• Reduce watering frequency
• Repot into fresh soil

• Often featured in botanical gardens and collections
• Rarity and unique leaf appearance
• Slowly gaining recognition in horticultural circles

• Glossy, dramatic foliage and rare status in cultivation
• Ideal for collectors who specialize in rare Aroids

Wild Population Status

• Considered vulnerable due to its limited geographic range and specialized habitat requirements
• Ongoing conservation efforts in Costa Rica and Panama to protect its native cloud forest habitats

Market Availability

• Not widely available on the market
• Appear in specialist nurseries or through botanical garden sales
