Anthurium espiranzaense Croat & Zuluaga

• Genus: Anthurium
• Botanical Background: The species was formally described by botanists Croat & Zuluaga in 2013. It is a part of the subgenus Anthurium, which includes over 1000 species of flowering plants known for their large, colorful spathes and spadices.

• Geographical Range: Native to the tropical rainforests of Colombia
• Environment: Thrives in humid, warm climates, with temperatures typically ranging from 70°F to 80°F (21°C to 27°C). It requires moist, well-draining soils and high humidity to mimic the conditions of its natural habitat.

Leaves

• Large, glossy, and lance-shaped, with dark green coloration and smooth texture
• Can grow up to 12–16 inches (30–40 cm) in length, making them visually striking and attractive

Inflorescence (Spadix & Spathe)

• Spathe of this species is typically white or cream in color, surrounding the yellowish-green spadix
• Inflorescence is held high above the foliage and is particularly noticeable due to its contrasting color

Growth Habit

• An epiphytic plant, meaning it grows on other plants or structures rather than in soil, using its roots for moisture absorption from the air

Light Requirements

• Prefers bright, indirect light, mimicking the dappled light found in its native rainforest habitat
• Direct sunlight can scorch the leaves, so it’s best to keep it in a spot with filtered light

Watering & Humidity

• Requires consistently moist conditions, but it should not be waterlogged
• Regular watering is important, especially in dry periods, and high humidity is essential for healthy growth
• Humidity level of 60% or higher is ideal

Soil & Potting Mix

• A well-draining, lightweight potting mix with organic matter, such as peat moss or orchid bark, is recommended
• Allow for proper moisture retention without risking root rot

Temperature & Fertilizer

• Ideal temperatures range from 70°F to 80°F (21°C to 27°C), with occasional drops at night to about 60°F (15°C)
• During the growing season, it benefits from monthly feeding with a balanced, water-soluble fertilizer

Division

• Propagation is typically done by dividing clumps of the plant or by taking stem cuttings that include at least one node
• Should be placed in a humid, warm environment until roots develop

Seeds

• Propagation is possible, it is not commonly used for Anthurium espiranzaense
• Germination can be slow and requires very high humidity and warmth to succeed

Typical Issues

• Spider mites, mealybugs, and aphids
• These pests can damage the plant by feeding on its sap, leaving behind marks and sometimes stunting growth
  

• Root rot can occur if the plant is kept in overly wet soil or if the container lacks proper drainage

Treatment Recommendations

• For pests, use insecticidal soap or neem oil to treat infestations
• Root rot can be prevented by ensuring proper drainage and avoiding excessive watering
• Removing damaged roots and repotting can help save the plant

• Rare and unique species, prized by plant collectors for its ornamental value
• Named after the area in which it was first discovered, further adding to its appeal for those interested in the biodiversity of Colombia's rainforest

• Glossy, large leaves and unique inflorescence make it a highly desirable species for tropical plant collections
• Typically used in indoor settings, providing an exotic touch with its striking appearance

Wild Population Status

• No immediate conservation concerns
• Like many tropical species, it may be affected by habitat destruction due to deforestation

Market Availability

• Not widely available in general garden centers, Anthurium espiranzaense can be found through specialized aroid collectors or rare plant nurseries

• Considered relatively rare and prized in the collector community
