Anthurium nangaritense Croat

• Genus: Anthurium
• Botanical Background: Described by aroid expert Thomas B. Croat, Anthurium nangaritense is named after the Nangaritza region in southern Ecuador where it was first collected.

• Geographical Range: Native to the Andean foothills of southern Ecuador
• Environment: Thrives in lower montane cloud forests at mid elevations (typically between 1,200–1,800 meters), where humidity is high and temperatures are mild year-round. It grows under dense canopy cover in moist, organic-rich soils.

Leaves

• Broadly cordate (heart-shaped), velvety to the touch, and medium to dark green with lighter primary and secondary veins
• Relatively thick, with a matte finish and prominent lobes at the base

Inflorescence (Spadix & Spathe)

• Inflorescence features a slender spadix, often white or pale green, accompanied by a narrow, green spathe
• Pollination is likely carried out by small beetles or gnats

Growth Habit

• Terrestrial to low-epiphytic grower that forms compact clumps from a short stem
• Robust roots suited to humid forest floors

Light Requirements

• Bright, indirect light
• Avoid direct sunlight to protect the velvety leaves from scorching

Watering & Humidity

• Maintain evenly moist soil and high humidity (above 75%)
• Allow the top layer of the substrate to dry slightly between waterings

Soil & Potting Mix

• Use a well-aerated mix, such as a blend of orchid bark, sphagnum moss, perlite, and peat
• Good drainage and moisture retention are essential

Temperature & Fertilizer

• Ideal temperatures range from 18–26°C (64–79°F)
• Fertilize monthly with a diluted balanced fertilizer during the growing season

Division

• Propagation is typically by division of established clumps or stem cuttings that include aerial roots
• High humidity and warmth aid rooting

Seeds

• Propagation is possible but rare outside of conservation or botanical settings
• Require consistently warm, moist conditions to germinate

Typical Issues

• Mealybugs, scale, or spider mites in dry conditions
• Overwatering can lead to root rot

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap
• Maintain airflow, use sterilized tools, and avoid overly compacted soil to reduce disease risks

• Named for the remote Nangaritza region
• Exemplifies the high biodiversity of Ecuador’s eastern slopes and is valued for its highly textured, ornamental foliage

• Lush, velvety leaves and bold venation
• Well suited for high-humidity terrarium setups or as a statement plant in shaded interiors

Wild Population Status

• Not formally assessed by the IUCN
• Wild populations may be vulnerable to deforestation and habitat degradations

Market Availability

• Rare in cultivation
• Offered by specialty nurseries or private collectors focused on velvet-leaved Anthurium species
