Anthurium arenasense Croat & D.C.Bay

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat and D.C. Bay, the species has been recognized for its distinct habitat preferences and aesthetic qualities, contributing to ongoing botanical research in tropical floral.

• Geographical Range: Tropical lowland forests
• Environment: Thrives under conditions of high humidity and stable, warm temperatures; favors well-draining soils rich in organic matter and grows best in shaded understory habitats with consistent moisture

Leaves

• Heart-shaped, large
• Glossy with a leathery texture
• Deep green color and smooth surface

Inflorescence (Spadix & Spathe)

• Spathe often displays a subtle yet attractive hue—ranging from creamy to light pink—encasing a spadix
• Inflorescence may emit a mild fragrance that aids in pollinator attraction

Growth Habit

• Primarily terrestrial, developing from a rhizomatous base. It typically forms clumps over time, a habit common among many Anthurium species

Light Requirements

• Bright, indirect light
• Direct sunlight can lead to leaf burn and should be avoided

Watering & Humidity

• Regular watering is essential to maintain a consistently moist soil, though it should never be waterlogged
• High humidity levels are crucial for optimal growth

Soil & Potting Mix

• A loose, well-aerated potting mix enriched with organic matter, such as a blend of peat and perlite, is ideal. Containers with excellent drainage are recommended

Temperature & Fertilizer

• Ideal temperature ranges between 65°F and 80°F (18°C to 27°C)

• During the growing season, a balanced, diluted fertilizer applied every few weeks helps support vigorous growth

Division & Cutting

• Most successful through careful division of the rhizomes during repotting. 

• Stem or node cuttings may also work when given proper care and environmental conditions

Seeds

• Less common in propagation due to variable germination rates; when employed, they require controlled conditions to achieve success

Typical Issues

• Spider, aphids and mealybugs
• Fungal issues and root rot

Treatment Recommendations

• Organic insecticidal soaps or neem oil are effective against pests
• Adjusting watering practices and ensuring adequate drainage can mitigate the risk of rot and fungal problems

• Celebrated among enthusiasts for its distinctive leaf shape and attractive inflorescence

• Sparked interest in botanical circles due to its specialized habitat and limited distribution

• Rarity and striking aesthetics make it a coveted specimen in tropical plant collections and among aroid enthusiasts seeking unusual decorative foliage

Wild Population Status

• May be vulnerable to habitat loss due to its limited distribution and specialized habitat

• Conservation initiatives in protected areas play a critical role in preserving its wild populations

Market Availability

• While not commonly found in mainstream horticultural outlets, this species is available through specialized collectors and botanical institutions, often commanding a premium price
