Anthurium acutissimum Engl.

• Genus: Anthurium
• Botanical Background: First described by Adolf Engler, A. acutissimum has long intrigued botanists for its unique morphology and adaptation to shaded forest environments.

• Geographical Range: Found in the tropical rainforests of Central and South America, with notable populations in countries like Colombia and Ecuador.
• Environment: Thrives in high-humidity, shaded forest floors with organic, well-draining soils and a consistently moderate climate.

Leaves

• Lanceolate and acutely pointed
• Glossy, deep green surface that exudes firmness and subtle elegance

Inflorescence (Spadix & Spathe)

• A modestly colored spathe
• A central spadix that supports specialized pollination

Growth Habit

• Terrestrial plant forms clumps from a rhizomatous base, making it well-suited for both indoor collections and greenhouse displays

Light Requirements

• Bright, indirect light to mimic its natural understory habitat

Watering & Humidity

• Keep the soil evenly moist without waterlogging; high humidity is ideal

Soil & Potting Mix

• Rich, well-aerated mix of peat, perlite, and organic matter in a container that offers excellent drainage

Temperature & Fertilizer

• Maintain temperatures between 65°F and 80°F
• Balanced, diluted fertilizer every 4 to 6 weeks

Division

• Most successful through division of the rhizomes during repotting

Stem Cuttings (if applicable)

• Node cuttings from stems can also be employed under suitable condition

Seeds

• Uncommon due to lower viability and extended germination periods

Typical Issues

• Spider mites and mealybugs
• Occasional root rot if overwatered

Treatment Recommendations

• Address infestations with insecticidal soap or neem oil
• Ensure proper drainage to prevent fungal infections

• Celebrated for its sharp, eye-catching foliage
• Plays a role in tropical understory ecology

• Its distinctive leaf shape and rarity make it a prized specimen among collectors and botanical enthusiasts

Wild Population Status

• No immediate conservation concerns, habitat loss in tropical regions is a general threat to many aroids

Market Availability

• Relatively rare in cultivation
• Typically available through specialist nurseries and botanical gardens
