Anthurium muscidiradix Croat & O.Ortiz

• Genus: Anthurium
• Botanical Background: Described by Thomas B. Croat and Orlando O. Ortiz, muscidiradix means “moss-rooted,” referencing the plant’s unusual root structures that resemble moss mats in its native habitat.

• Geographical Range: Endemic to Colombia, specifically the western slopes of the Andes
• Environment: Thrives in very humid environments, often growing in moss-covered soil or epiphytically. Conditions include filtered light, frequent rain, and cool, stable temperatures.

Leaves

• Narrow to lanceolate, deep green, and slightly leathery
• Smooth margins and grow on slender, upright petioles

Inflorescence (Spadix & Spathe)

• Spadix is thin and light-colored, paired with a green to whitish spathe
• Floral scent is minimal
• Pollinated by beetles or small flies

Growth Habit

• Epiphytic or terrestrial
• Grows from short stems with prominent, hair-like roots that cling to moss and bark, giving it its name

Light Requirements

• Bright, indirect light
• Avoid direct sun to preserve delicate foliage

Watering & Humidity

• Requires consistently moist soil and high humidity (above 75%)
• Mist regularly or grow in a humidity-controlled environment

Soil & Potting Mix

• Use a very airy, moisture-retentive mix of sphagnum moss, orchid bark, and perlite
• Excellent drainage is essentials

Temperature & Fertilizer

• Best kept between 18–24°C (64–75°F)
• Apply a diluted balanced fertilizer monthly during active growth

Division

• Propagate by stem division or cuttings with visible nodes and roots
• Maintain high humidity for rooting success

Seeds

• Viable but are not widely available
• Germination requires consistent warmth and moisture

Typical Issues

• Mealybugs, spider mites, or fungal leaf spots
• Susceptible to root rot if overwatered or grown in compact soil

Treatment Recommendations

• Use neem oil or insecticidal soap on pests
• Ensure airflow and well-drained substrate to prevent fungal issues

• Name reflects its moss-like root structures, which help it cling to moist forest substrates
• Collect nutrients in epiphytic environments

• Highly attractive to collectors for its unusual root system and adaptability to terrarium or vivarium conditions
• Well-suited to naturalistic setups

Wild Population Status

• Not formally assessed
• Restricted range and dependence on cloud forest ecosystems, habitat loss may pose a risk

Market Availability

• Extremely rare in cultivation
• Found through specialty collectors or botanical institutions focused on conservation
