Anthurium attenuatifolium Croat

• Genus: Anthurium
• Botanical Background: Described by renowned botanist Thomas B. Croat, Anthurium attenuatifolium has been recognized in modern botanical literature for its unique leaf characteristics and refined growth structure.

• Geographical Range: Indigenous to tropical regions of South America
• Environment: Thrives in warm, humid conditions with well-draining, organic-rich soils; favors environments with consistent moisture and filtered light typical of understory rainforest habitats

Leaves

• Notably elongated and taper to a fine point
• Glossy texture and subtle venation

Inflorescence (Spadix & Spathe)

• Small spadix surrounded by a delicate spathe
• Coloration is understated and may vary slightly, functioning primarily to attract specific pollinators

Growth Habit

• Exhibits a terrestrial habit with a clumping growth pattern, developing from a rhizomatous base rather than forming aerial roots

Light Requirements

• Bright, indirect light that mimics the dappled sunlight of a forest understory

Watering & Humidity

• Requires regular watering to maintain consistently moist soil without becoming waterlogged
• High humidity is essential to support its tropical origins

Soil & Potting Mix

• A well-draining, organic-rich potting mix is ideal
• A container that allows for proper drainage will help prevent root rot

Temperature & Fertilizer

• Prefers a warm temperature range between 65°F and 80°F
• Feed lightly during the growing season with a balanced fertilizer to promote steady growth

Division and Cuttings

• Most common propagation method is through division of the rhizomatous clumps

Seeds

• Less commonly practiced due to lower germination success and a longer establishment period

Typical Issues

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

Treatment Recommendations

• Effective treatments include using insecticidal soap
• Organic remedies and ensuring proper watering techniques to prevent fungal infections

• Tapered leaves provide a unique twist on the typical Anthurium silhouette, making it a subject of interest in botanical studies and plant enthusiast circles

• Prized for its unusual leaf shape and compact form, which make it an attractive and rare addition to curated indoor plant collections

Wild Population Status

• Deforestation and habitat disturbance in tropical regions pose potential threats to its natural populations, warranting attention from conservationists

Market Availability

• Not commonly found in mainstream nurseries, this species is highly sought after by specialized collectors and botanical enthusiasts
