Anthurium auritum Sodiro

• Genus: Anthurium
• Botanical Background: First described by the botanist Luis Sodiro, this species has been studied for its unique morphology and adaptation to rainforest conditions.

• Geographical Range: Native to tropical rainforests, particularly in regions of Ecuador.
• Environment: Thrives in consistently moist, well-draining soils with high organic matter and favors high humidity and moderate temperatures typical of cloud forests and lower montane regions.

Leaves

• Broad, heart-shaped
• Soft, velvety texture
• Prominent venation and deep green color

Inflorescence (Spadix & Spathe)

• Modest spadix accompanied by a greenish spathe
• Plays a role in the plant’s reproductive strategy, often attracting specific pollinators

Growth Habit

• Typically epiphytic or lithophytic
• Grows on trees or rocks in its natural habitat
• Develops a rhizomatous base that supports its growth in diverse substrates

Light Requirements

• Bright, indirect light

• Direct sunlight can scorch its delicate leaves

Watering & Humidity

• Keep the soil consistently moist
• High humidity levels
• Misty indoor environments or greenhouses, are beneficial

Soil & Potting Mix

• A well-draining mix with components like orchid bark, peat, and perlite
• Container with drainage holes

Temperature & Fertilizer

• Optimal temperatures range from the mid-60s to low 80s °F
• Balanced, diluted fertilizer monthly for best results

Division and Cuttings

• The most common propagation method is through division of the rhizomatous clumps

Seeds

• Less common among hobbyists due to longer germination periods and variable success rates

Typical Issues

• Spider mites, mealybugs, and aphids
• Overwatering may lead to root rot

Treatment Recommendations

• Neem oil or insecticidal soap 
• Ensuring proper air circulation and watering practices 

• Unique, textured leaves have made it a favorite in modern interior landscaping
• Inspired interest in its ecological role within rainforest ecosystems

• Prize this species for its ornamental foliage and relatively low maintenance requirements
• Excellent choice for both indoor and greenhouse settings

Wild Population Status

• Habitat loss and deforestation pose potential risks

Market Availability

• Moderately available in the horticultural trade
• Remains a sought-after addition for collectors and aroid enthusiasts
