Anthurium macphersonii Croat & Oberle

• Genus: Anthurium
• Botanical Background: First described by botanists Croat and Oberle, contributing to the understanding of Anthurium diversity in tropical habitats.

• Geographical Range: Native to Central America, found primarily in Panama and Costa Rica, where it grows in shaded, humid rainforest environments.
• Environment: Thrives in conditions characterized by high humidity, well-drained soils, and consistent temperatures. These environments support its growth under the canopy of tropical forests, where it can receive indirect sunlight.

Leaves

• Elongated, glossy
• Dark green, with a smooth texture
• Distinct shape and size (up to 40 cm long) help the plant blend into its dense rainforest habitat

Inflorescence (Spadix & Spathe)

• Spadix is long and narrow, contrasting with the white or cream-colored spathe
• Has a subtle scent
• Designed to attract specific pollinators such as flies

Growth Habit

• Primarily epiphytic, meaning it often grows on trees or other structures in its native habitat
• Lacks tubers but forms rhizomes that allow it to spread and establish itself in suitable environments

Light Requirements

• Bright; indirect light
• Avoid direct sunlight to prevent leaf scorch

Watering & Humidity

• Keep the soil consistently moist with excellent drainage to avoid waterlogging
• High humidity is essential for optimal growth; should be above 60%

Soil & Potting Mix

• A well-draining, loamy mix with added organic matter is best
• A mix of peat, perlite, and pine bark is recommended for optimal growth

Temperature & Fertilizer

• Ideal temperatures between 18°C and 28°C (64°F to 82°F)
• Balanced fertilizer every month during the growing season

Division and Cuttings

• Division of the rhizomes
• Healthy section of the plant with roots is separated and replanted

Seeds

• Less common but possible with proper humidity and warmth
• Slow and less practical than division

Typical Issues

• Spider mites, mealybugs, and scale insects
• Overwatering can lead to root rot or fungal infections
• Proper drainage and careful watering are essential

Treatment Recommendations

• Organic treatments like neem oil or insecticidal soap are effective for controlling pest infestations
• Adjust watering practices and improve air circulation to prevent fungal issue
• Use chemical treatments sparingly when necessary

• Excellent ornamental plant prized for its large, glossy leaves
• Has a unique ability to thrive in low light and high humidity

• Highly valued for its bold foliage
• A popular choice in decorative plant collections and as an accent plant in homes and offices

Wild Population Status

• Plays an important role in its natural habitat by stabilizing soil in the rainforest understory
• Part of traditional tropical horticulture

Market Availability

• Prized for its striking foliage and unique floral structure
• Rarity in cultivation adds to its allure among collectors
