Anthurium maasii Croat

• Genus: Anthurium
• Botanical Background: First described by the botanist Thomas B. Croat in 1978. The species is part of the diverse group of anthuriums that are primarily found in Central and South America.

• Geographical Range: Found in the lowland tropical forests of Costa Rica and Panama, typically at elevations ranging from sea level to 1,200 meters.
• Environment: Thrives in humid, well-drained soils in shaded areas with high humidity, typical of rainforest environments; prefers consistently warm temperatures and does well in areas with moderate rainfall throughout the year.

Leaves

• Large, dark green
• Glossy with a heart-shaped appearance
• Can grow up to 50 cm in length
• Have a smooth, leathery texture

Inflorescence (Spadix & Spathe)

• Spathe is white, broad, and arching, surrounding a yellowish-green spadix
• Quite striking, though not particularly fragrant
• Pollination occurs involving heat and scent to attract specific insect pollinators

Growth Habit

• Terrestrial, growing from a rhizomatous root system
• Does not climb like many other Anthurium species but remains rooted to the forest floor

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 (60%-70%) is essential for optimal growth

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  20°C to 30°C (68°F to 86°F)
• Balanced, water-soluble fertilizer during the growing season, typically every 2–4 weeks

Division and Cuttings

• Division of the rhizomes during the spring or early summer

Seeds

• Require specific conditions for germination and are not commonly used in cultivation due to the time and care needed

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

• Named in honor of the botanist Massimo Maas
• Prized for its attractive foliage and unique flower structure

• Commonly grown as a decorative houseplant, especially in humid regions or greenhouses

Wild Population Status

• Not currently listed as endangered
• Habitat destruction in tropical rainforests can pose a potential threat to its long-term survival

Market Availability

• Not widely available in the market compared to other Anthurium species
• Occasionally cultivated by enthusiasts and collectors
• Considered moderately rare
