Anthurium alatum Engl.

• Genus: Anthurium
• Botanical Background: Described by Adolf Engler, a prominent botanist specializing in tropical Araceae. While not as commonly encountered as some ornamental Anthurium species, it remains a point of interest for collectors due to its unique morphology.

• Geographical Range: Found in humid, tropical regions of Central and South America, often in mid-elevation rainforests.
• Environment: Prefers moist, shaded understories with ample humidity, typically growing as an epiphyte on tree trunks or occasionally rooted in leaf litter on the forest floor.

Leaves

• Winged petioles (the “alatum” in its name refers to these wing-like structures)
• Elliptical or lanceolate blade with a glossy texture
• Medium to deep green coloration

Inflorescence (Spadix & Spathe)

• Slender, upright spadix, often greenish or pale yellow
• Subtle, sometimes greenish spathe that may go unnoticed compared to showier species
• Pollination often facilitated by small insects attracted to the spadix

Growth Habit

• Epiphytic or hemiepiphytic in nature, occasionally terrestrial
• Tends to form loose, rosette-like clusters of foliage

Light Requirements

• Bright, filtered light mimicking its natural understory conditions
• Avoid direct, intense sunlight that can scorch leaves

Watering & Humidity

• Keep soil or growing medium slightly moist but not waterlogged
• Benefits from high humidity (60–80%), mirroring its rainforest habitat
• Mist leaves or use a humidifier in dry indoor environments

Soil & Potting Mix

• A well-draining, chunky aroid mix (bark chips, perlite, and peat or coco coir)
• Good aeration helps prevent root rot

Temperature & Fertilizer

• Thrives between 65–85°F (18–29°C)
• Balanced liquid fertilizer at half-strength every 4–6 weeks during active growth

Division

• Carefully separate offsets or clumps at the base, ensuring each has its own root system

Stem Cuttings (if applicable)

• Can be propagated from stem segments with aerial roots

Seeds

• Less common for home growers; requires controlled pollination and patience for germination

Typical Issues

• Spider mites, mealybugs, and scale insects
• Root rot can occur if overwatered or kept in poorly draining soil

Treatment Recommendations

• Isolate infected plants and treat with neem oil or insecticidal soap
• Ensure proper watering habits and adequate airflow

• The term “alatum” means “winged,” referencing its distinct petiole structure
• Less showy than the classic “flamingo flower” types, but prized by collectors for its unique foliage

• Adds a subtle, tropical charm to indoor gardens and specialized aroid collections
• Ideal for enthusiasts interested in uncommon Anthurium diversity

Wild Population Status

• Specific conservation data for A. alatum is not widely documented, but habitat loss in tropical forests remains a concern

Market Availability

• Occasionally available through specialty aroid nurseries and collectors
• May require some searching or importing for those outside its native range
