Anthurium titanium Standl. & Steyerm.

• Genus: Anthurium
• Botanical Background: Described by botanists Standley and Steyermark in 1952, this species was first identified in the wild in the cloud forests of Colombia and Ecuador. It remains a prime example of large-leaved anthuriums.

• Geographical Range: Native to the foothills of the Andes in Colombia and Ecuador, found at elevations of around 1,500 to 2,000 meters.
• Environment: Thrives in humid, tropical rainforests with temperatures ranging from 18-25°C; it favors rich, well-drained soils in shaded environments, often growing in areas with high humidity and consistent moisture.

Leaves

• Large, leathery, and dark green, with a glossy texture
• Lanceolate in shape and can grow up to 1 meter long
• The veins are prominently raised, creating a striking, textured surface

Inflorescence (Spadix & Spathe)

• Features a unique, dark purple to black spathe, which envelops a white spadix
• The spadix is approximately 20-30 cm long, with a subtle scent that attracts pollinators
• Pollination is thought to be primarily wind-assisted

Growth Habit

• A terrestrial plant that forms large, clumping growths from an underground rhizome
• Can also be found growing epiphytically in some areas, particularly in regions with dense foliage

Light Requirements

• Prefers bright, indirect light
• Direct sunlight can scorch its large leaves, so filtered light or partial shade is ideal

Watering & Humidity

• Requires consistent moisture but should never sit in stagnant water
• High humidity is essential for healthy growth, ideally above 60%

Soil & Potting Mix

• Thrives in a well-draining, aerated potting mix, such as a blend of peat, perlite, and orchid bark
• Ensure that the container allows excess water to drain away

Temperature & Fertilizer

• Maintain temperatures between 18°C and 25°C
• Balanced liquid fertilizer monthly during the growing season (spring and summer) to encourage robust growth

Division

• Can be achieved by dividing the rhizome
• Should be rooted in moist, well-drained soil

Stem Cuttings (if applicable)

• Taking stem cuttings that include a node
• Should be rooted in moist, well-drained soil

Seeds

• Rarely done in cultivation; must be sown in a sterile medium and kept at high humidity for successful germination

Typical Issues

• Mealybugs, aphids, and scale
• Root rot can occur if the plant is kept too moist or in poorly-drained soil

Treatment Recommendations

• Treat infestations with insecticidal soap or neem oil
• For root rot, ensure proper drainage, and remove affected roots
• A fungicide may be necessary in severe cases
  

• Relatively rare in the wild and is sought after by collectors for its impressive leaf size and unique appearance
• Has also been described as one of the largest-leaved anthuriums

• Its striking foliage and large leaves make it a sought-after ornamental plant for large indoor spaces, conservatories, and botanical gardens
• Especially prized for its rarity and dramatic form

Wild Population Status

• Not currently considered endangered, but its natural habitat is increasingly threatened by deforestation
• Conservation efforts are underway to protect its native regions
  

Market Availability

• Not widely available
• Can occasionally be found through specialized plant sellers or as a rare ornamental
