Anthurium llewellynii Croat

• Genus: Anthurium
• Botanical Background: The species was described by Croat, a leader in aroid research, whose work has significantly advanced the scientific understanding of this complex and diverse genus.

• Geographical Range: Native to select tropical regions of South America.
• Environment: Thrives in the shaded understory of tropical rainforests, favoring well-drained, humus-rich soils in areas with high humidity and a stable, warm climate.

Leaves

• Broad leaves
• Glossy dark green surface
• Attractive shape that may include subtle undulations or defined margins

Inflorescence (Spadix & Spathe)

• Modestly colored spathe
• Central spadix
• Not noted for an intense fragrance

Growth Habit

• Terrestrial plant with a rhizomatous base that allows for moderate clumping over time
• Well suited to container culture as well as greenhouse settings

Light Requirements

• Bright, indirect light
• Direct sunlight should be avoided to prevent leaf scorch
  

Watering & Humidity

• Requires evenly moist soil and high humidity
• Watering should be regular yet moderate to ensure good drainage and to prevent root rot

Soil & Potting Mix

• A well-draining, airy mix rich in organic matter is ideal
• A blend that includes peat, perlite, and orchid bark often works well for supporting its growth

Temperature & Fertilizer

• Prefers warm temperatures between 65°F and 80°F
• Balanced, water-soluble fertilizer at monthly intervals during the growing season and reduce feeding in the winter months

Division and Cuttings

• Most common propagation method is rhizome division
• Healthy offshoots can be carefully separated and replanted to develop into mature plants

Seeds

• Less common due to the variable viability and slower germination rate
• Enthusiasts usually favor division for faster and more predictable growth
  

Typical Issues

• Spider mites and mealybugs
• Root rot may also occur if the soil remains too wet

Treatment Recommendations

• Management typically involves the use of insecticidal soap or neem oil for pests
• Improved air circulation and appropriate watering practices can help prevent fungal issues and root rot

• Noted for its unusual leaf form
• Has attracted attention in horticultural circles for its rarity
• Attributed for a special cultural or aesthetic value to its unique appearance

• Prized for its striking foliage and uncommon inflorescence
• Relative rarity in cultivation enhances its appeal to dedicated plant enthusiasts and specialized aroid collectors

Wild Population Status

• Some concern about its status in the wild due to deforestation and habitat change in tropical regions
• Conservation initiatives may be in place to monitor and protect native populations

Market Availability

• Considered rare in the horticultural market
• Typically available only through specialist aroid nurseries and dedicated collectors
