Anthurium petrophilum K.Krause

• Genus: Anthurium
• Botanical Background: Described by botanist K. Krause, this species has contributed to understanding ecological specialization within aroids, particularly those adapted to rocky and well-drained habitats.

• Geographical Range: Indigenous to select tropical regions where rocky outcrops and limestone formations prevail.
• Environment: Thrives in humid tropical climates with well-drained, rocky soils and benefits from moderate temperatures, consistent moisture without waterlogging, and high ambient humidity.

Leaves

• Broad, leathery leaves
• Glossy finish and subtle venation

Inflorescence (Spadix & Spathe)

• Slender spadix accompanied by a modest spathe
• Not notably fragrant, this structure is essential for the plant’s pollination

Growth Habit

• Adapts to rocky surfaces using a rhizomatous root system 

Light Requirements

• Bright, indirect light
• Mimics the dappled sunlight of its natural forested, rocky environment

Watering & Humidity

• Consistent moisture without overwatering
• Ensure high humidity

Soil & Potting Mix

• A well-draining mix enriched with organic matter

Temperature & Fertilizer

• Range from 65°F to 80°F
• Feed monthly with a balanced, diluted fertilizer

Division

• Most reliable propagation method is through rhizome division

Seeds

• Less common due to variable germination rates and a longer time to reach maturity

Typical Issues

• Spider mites and mealybugs
• Root rot, particularly in overly moist conditions

Treatment Recommendations

• Organic insecticidal soap or neem oil
• Ensure proper drainage

• Adaptation to rocky habitats
• Unique ecological niche also adds to its allure among botanical enthusiasts

• Prize for its unusual habitat preference and the striking appearance of its glossy foliage
• Coveted specimen in aroid collections

Wild Population Status

• Not widely documented as endangered

Market Availability

• Relatively rare in cultivation
