Introduction & Overview
Common and Scientific Names
- Scientific Name: Anthurium citrifolium Sodiro.
- Common Name: Lime green anthurium, though not widely known by a common name
Quick Facts
- Origin: Found in the cloud forests and tropical regions of South America, particularly in Ecuador and Colombia
- Features: Most notable features include large, heart-shaped leaves and its distinctive spadix inflorescence
Taxonomy & Classification
- Genus: Anthurium
- Botanical Background: Named by Ecuadorian botanist Luis Sodiro, Anthurium citrifolium was first described in the late 19th century. It is part of a larger group of Anthurium species known for their ornamental qualities.
Natural Habitat & Distribution
- Geographical Range: Native to the highland rainforests of Ecuador and Colombia, Anthurium citrifolium is typically found in areas with high humidity and rainfall at mid-to-high elevations.
- Environment: Thriving in cloud forests, this species prefers a cool, humid environment. Favors rich, well-draining soils and grows in the understory where it receives filtered light.
Morphological Characteristics
Leaves
- Large, leathery, and heart-shaped, typically 30-45 cm long
- Dark green leaves often have a glossy texture
- Exhibit a smooth, prominent venation pattern
Inflorescence (Spadix & Spathe)
- The spadix is cylindrical, often yellow or cream-colored, and surrounded by a large, white spathe
- Has a mild, somewhat sweet fragrance, though it is not overpowering
Growth Habit
- A terrestrial plant that grows from a rhizomatous base, forming dense clumps
- Does not climb but spreads horizontally in its native environment
Cultivation & Care
Light Requirements
- Prefers bright, indirect light
- Direct sunlight may scorch its leaves, so it’s best to place it in a spot with filtered light
Watering & Humidity
- Requires consistent watering, keeping the soil lightly moist but not waterlogged
- High humidity is ideal
- Regular misting or a humidity tray is beneficial
Soil & Potting Mix
- Prefers a rich, well-draining potting mix such as one with peat, perlite, and orchid bark
- Ensure the pot has good drainage to prevent root rot
Temperature & Fertilizer
- Ideal temperatures range from 18-26°C (65-78°F)
- Fertilize with a balanced, water-soluble fertilizer during the growing season every 4-6 weeks
Propagation Methods
Division
- Propagation can be done by dividing the rhizome
Stem Cuttings (if applicable)
- Done by taking stem cuttings with a node
- Rooting hormone can help in promoting faster root growth
Seeds
- Though viable, seed propagation is less common
- Seeds require moist conditions and a temperature of about 25°C (77°F) for successful germination
Common Pests & Diseases
Typical Issues
- Common pests include aphids, spider mites, and mealybugs
- Root rot can occur if overwatered or kept in poorly draining soil
Treatment Recommendations
- Use neem oil or insecticidal soap for pests
- For root rot, ensure the soil is well-draining and avoid overwatering
- Repotting and trimming affected roots may help
Notable Traits & Uses
- Not only valued for its aesthetic appeal but also plays a role in its native ecosystem, providing shelter and nutrients for a variety of smaller forest organisms
- Prized for its bold, glossy leaves and unique floral structures
- An attractive addition to high-end tropical plant collections
Conservation & Availability
Wild Population Status
- While not currently classified as endangered, its population is vulnerable due to habitat loss from deforestation in its native regions
Market Availability
- Not as common as other Anthurium species
- Can be found in select nurseries, particularly in specialized collections of tropical plants
