Anthurium luteospathum Croat

• Genus: Anthurium
• Botanical Background: Described by botanist Thomas B. Croat in 1983. It is part of the subgenus Anthurium section Dendrobulbium, which includes other species known for their unique inflorescences and growth forms.

• Geographical Range: Native to the tropical lowland rainforests of Costa Rica and Panama. It is typically found at altitudes ranging from 100 to 500 meters above sea level.
• Environment: Thrives in humid, consistently warm environments with well-drained, rich soils. It prefers a climate with frequent rainfall and relatively stable temperatures between 22°C and 30°C.

Leaves

• Large, glossy
• Dark green, with a slightly corrugated texture
• Lanceolate shape and can grow up to 30 cm in length

Inflorescence (Spadix & Spathe)

• Spathe is bright yellow, elongated, and waxy, surrounding the creamy-white spadix
• Typically around 10 cm in length
• Pollinated by insects attracted to its vibrant color and scent

Growth Habit

• Terrestrial, typically growing in the leaf litter of tropical forests
• Has a creeping rhizome that helps it spread through 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%-80%) is crucial

Soil & Potting Mix

• A loose, well-draining potting mix rich in organic matter is recommended
• A blend incorporating orchid bark, peat, and perlite offers ideal aeration and moisture retention

Temperature & Fertilizer

• Ideal temperatures between 22°C and 30°C
• Balanced water-soluble fertilizer diluted to half strength done every 4–6 weeks

Division and Cuttings

• Division of the rhizomes during the spring
• Each division should have at least one growing shoot and roots

Seeds

• Less commonly practiced due to variable germination rates
• Require a warm, humid environment to sprout effectively

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

• Found growing in the moist understory of tropical rainforests
• Not commonly cultivated outside of specialized aroid collections

• Prized for its unusual yellow spathe and striking appearance
• A desirable addition to ornamental plant collections

Wild Population Status

• Not currently listed as endangered
• Habitat loss and deforestation in its native regions may impact its population in the wild

Market Availability

• Rare in cultivation 
• May be available through specialized nurseries or aroid collections
