Anthurium ochranthum K.Koch

• Genus: Anthurium
• Botanical Background: Described by German botanist Karl Koch in 1854. Koch made significant contributions to the study of tropical plants, particularly within the Araceae family.

• Geographical Range: Endemic to the tropical regions of Colombia and Ecuador, where it flourishes in cloud forests and moist, lowland areas.
• Environment: Thrives in humid environments with stable temperatures, generally preferring temperatures between 20-28°C (68-82°F); it grows in soils rich in organic matter and benefits from filtered light and high humidity.

Leaves

• Large, heart-shaped, and glossy, measuring up to 30 cm (12 inches) in length
• Vibrant dark green, with prominent venation that adds to their visual appeal

Inflorescence (Spadix & Spathe)

• Characterized by a white spadix and a typically white spathe
• Pollination occurs primarily through insects attracted to the spathe, which is sweetly scented during flowering

Growth Habit

• Terrestrial, typically growing on the forest floor
• Has a creeping growth habit and produces a rhizome from which the leaves emerge

Light Requirements

• Best grown in bright, indirect light
• Direct sunlight can scorch the leaves, leading to discoloration

Watering & Humidity

• Regular watering is necessary, but the soil should never remain soggy
• Thrives in high humidity, typically between 60-80%
• Misting the leaves can help maintain moisture levels

Soil & Potting Mix

• A well-draining, peat-based potting mix with added organic matter for increased moisture retention
• A mix designed for aroids or orchids works well

Temperature & Fertilizer

• Prefers temperatures in the range of 20-28°C (68-82°F)
• Balanced liquid fertilizer every month during the growing season (spring through summer)

Division

• Best achieved through rhizome division

Stem Cuttings (if applicable)

• Stem cuttings with a node is also common
• Cuttings should be placed in a humid environment to encourage rooting
  

Seeds

• Less common; require a warm, moist environment and may take longer to germinate than vegetative methods

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot is also a concern if the plant is overwatered

Treatment Recommendations

• Use insecticidal soap or neem oil for pest management
• For root rot, ensure the plant has good drainage and reduce watering
• If necessary, remove affected roots and repot in fresh soil
  

• Used in decorative floral arrangements
• Primarily grown for its ornamental value in horticulture

• Its glossy, attractive foliage and moderate growth habit make it a sought-after species for collectors and a striking addition to any indoor plant collection

Wild Population Status

• There are no specific conservation concerns currently, but like many tropical plants, it faces threats from habitat destruction due to deforestation

Market Availability

• Not commonly found in mass-market stores
• Available through specialty nurseries and collectors' circles
