Anthurium chrysolithos Croat & Oberle

• Genus: Anthurium
• Botanical Background: Described by noted botanists Croat and Oberle, this species has attracted interest due to its unusual morphology and limited distribution, contributing valuable insights into the evolution of the Anthurium genus.

• Geographical Range: Native to select regions of tropical South America, typically found in areas with rich biodiversity such as tropical rainforests and high-altitude cloud forests.
• Environment: Naturally thrives in humid, well-drained conditions with moderate to high moisture levels, preferring loose, organically enriched soils and a climate that offers consistent warmth and filtered light.

Leaves

• Large and leathery
• With a deep green coloration accented by unique veining
• Subtle metallic hints that may evoke a golden appearance

Inflorescence (Spadix & Spathe)

• Features a spadix surrounded by a vibrant spathe that displays contrasting hues
• Not noted for a strong scent
• Structure is well adapted to attract specialized pollinators

Growth Habit

• Typically terrestrial, Anthurium chrysolithos grows from a robust rhizome
• Forms a compact clump rather than sprawling vines, making it suitable for both ground planting and container cultivation

Light Requirements

• Bright, indirect light

Watering & Humidity

• Regular watering is essential to maintain consistently moist soil
• High ambient humidity
• Care should be taken to avoid waterlogging

Soil & Potting Mix

• A well-draining potting mix rich in organic matter is ideal
• A mix incorporating peat, perlite, and orchid bark supports both moisture retention and aeration

Temperature & Fertilizer

• Prefers a stable temperature range between 65°F and 80°F
• Balanced, water-soluble fertilizer applied monthly during the growing season supports its growth

Division and Cuttings

• Division of the rhizome
• Careful separation of offsets ensures each new plant retains adequate root mass
  

Seeds

• Less common due to the species’ slow germination and the precision required to replicate its optimal growing conditions

Typical Issues

• Spider mites and mealybugs
• Risks of root rot if overwatered

Treatment Recommendations

• Both chemical and organic treatments can be effective
• Insecticidal soaps or neem oil provide safe options
• Ensuring the plant’s environment is not conducive to disease development

• Captured the attention of botanists and hobbyists alike due to its limited natural occurrence and the mystery surrounding its evolution
• Prized for its rare and unique leaf structure

• A desirable specimen for tropical plant collections and high-end indoor landscaping

Wild Population Status

• Due to its restricted geographical distribution, there are ongoing conservation efforts to monitor and protect its natural habitat
• Considered rare in the wild

Market Availability

• Typically found only in specialized collections and among dedicated enthusiasts
• A sought-after and relatively rare specimen in the horticultural market
