Anthurium chimborazense Croat & Carlsen

• Genus: Anthurium
• Botanical Background: First described by botanists Croat and Carlsen in 1984. Their work on the Anthurium genus helped clarify the relationship between various Andean species and highlighted A. chimborazense as a distinct high-altitude speciesy.

• Geographical Range: Endemic to the cloud forests of the Ecuadorian Andes, particularly around the Chimborazo region; adapted to the cooler, high-elevation habitats typical of this area.
• Environment: Thrives in humid environments with consistent rainfall, moderate temperatures, and well-drained, organic-rich soils. Naturally grows in shaded areas of cloud forests, where the humidity is high and the light is diffused through the canopy.

Leaves

• Large, leathery, and dark green
• Glossy texture
• Typically heart-shaped and can reach up to 30 cm in length, with pronounced veins giving them a distinct texture

Inflorescence (Spadix & Spathe)

• Consists of a pale green spathe that wraps around a yellowish spadix
• Flowers are small and unassuming, with the spathe offering some protection from the elements
• Pollination is primarily achieved through insect visitation, typical of many Anthurium species

Growth Habit

• Primarily terrestrial but can exhibit epiphytic growth in its native habitat
• Produces a thick rhizome that helps anchor the plant while supporting its large leaves. The species does not produce tubers like some other Aroids

Light Requirements

• Bright, indirect light
• Direct sunlight can scorch its leaves, making filtered or diffused light ideal for healthy growth

Watering & Humidity

• Prefers consistently moist soil, but waterlogging should be avoided
• Requires high humidity, typically above 60%
• Suitable for tropical environments or humidifiers in indoor settings

Soil & Potting Mix

• A well-draining potting mix rich in organic matter is recommended
• A blend of peat, perlite, and pine bark works well for this species, ensuring good moisture retention while preventing root rot

Temperature & Fertilizer

• Ideal temperatures range from 18 to 25°C (64 to 77°F)
• Balanced, water-soluble fertilizer every 4-6 weeks supports healthy growth

Division

• The most common propagation method is by division, particularly when the plant has outgrown its pot

Stem Cuttings (if applicable)

• Stem cuttings taken from mature plants can root in water or moist soil

Seeds

• Less common but can be achieved with fresh seeds
• Require a warm, humid environment to germinate successfully

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot can also be a concern

Treatment Recommendations

• To combat pests, insecticidal soap or neem oil is effective
• For root rot, reduce watering and ensure the soil is well-draining
• For infestations, remove affected leaves and treat with a mild pesticide
  

• Named after Mount Chimborazo, Ecuador’s highest peak, where it was first discovered
• Has cultural significance in the Andean region as a symbol of the region’s unique biodiversity

• Prized for its striking, large foliage and its relatively rare status in cultivation
• Its adaptability to cooler conditions makes it an appealing choice for temperate climates where other Aroids may struggle

Wild Population Status

• While not currently listed as endangered, considered rare and faces potential threats from habitat destruction and climate change in the highland regions of Ecuador

Market Availability

• Not widely available in the market, especially outside of specialized Aroid or tropical plant nurseries
• Considered a collector’s plant due to its relatively limited distribution
