Anthurium dolichocnemum Croat

• Genus: Anthurium
• Botanical Background: First described by renowned botanist Thomas B. Croat in 1983, this species was identified in the rainforests of Central America. Croat is well-known for his extensive work on the Aroid family

• Geographical Range: native to the lowland and montane rainforests of Panama and Costa Rica
• Environment: This species thrives in high-humidity environments with consistently warm temperatures. It prefers moist, well-drained soils and is usually found in shaded understory areas, where it enjoys indirect light and consistent moisture

Leaves

• Leaves are large, glossy
• Deep green
• Heart-shaped with a smooth texture
• They can grow up to 30 cm long and are slightly leathery in feel
• Leaves may have faint venation

Inflorescence (Spadix & Spathe)

• The spathe is a pale green to white, creating a striking contrast with the darker foliage. The spadix is long and cylindrical, often elongating to 10 cm or more. While this species doesn’t have a strongly pungent scent

Growth Habit

• Anthurium dolichocnemum is an epiphytic plant, meaning it grows on other plants without parasitizing them. It uses aerial roots to anchor itself in the humid environments of rainforests. It lacks tubers or rhizomes but forms dense clumps as it grows

Light Requirements

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

Watering & Humidity

• High humidity (60% or more) is crucial for this species. Water regularly to keep the soil moist but not soggy. A misting regimen can be beneficial, especially in drier conditions

Soil & Potting Mix

• A well-draining, acidic potting mix, such as a blend of orchid bark, perlite, and peat, is ideal. It benefits from being grown in a container that allows for air circulation around the roots

Temperature & Fertilizer

• This species prefers temperatures between 20-27°C (68-80°F)
• Fertilize monthly with a balanced liquid fertilizer during the growing season, reducing frequency in the winter months
  

Division and Cuttings

• The most common propagation method is by division. Cuttings from mature plants with at least one node and aerial roots can also be rooted in moist conditions

Seeds

• While seed propagation is possible, it is more complicated and slower than using vegetative methods. Seeds require warm, moist conditions to germinate

Typical Issues

• Spider mites; phidsand mealybugs
• Overwatering may lead to root rot

Treatment Recommendations

• For pests, neem oil or insecticidal soap can be effective. For root rot, ensure the plant is not waterlogged and consider repotting into fresh soil. Use fungicide if necessary

• Anthurium dolichocnemum is noted for its distinct, elongated spadix, making it an interesting focal point in tropical plant collections. It is not commonly seen in cultivation outside of specialist collections

• The striking foliage and spadix make it highly desirable for tropical plant enthusiasts, particularly those focusing on rare and unusual Aroids. Its epiphytic nature also makes it suited for cultivation in terrariums or indoor rainforests

Wild Population Status

• There are no significant conservation concerns regarding Anthurium dolichocnemum at present, although habitat loss in Central America could affect its wild populations

Market Availability

• This species is considered rare in cultivation, primarily available to specialized collectors or those involved in the Aroid trade. It is not widely distributed in commercial nurseries
