Anthurium angustifolium Theófilo & Sakur.

• Genus: Anthurium
• Botanical Background: First described by Theófilo and Sakur, this species has intrigued botanists due to its subtle yet distinctive features. Its classification reflects ongoing research in tropical botany and the evolving understanding of Anthurium diversity.

• Geographical Range: Native to tropical rainforests where high humidity and moderate temperatures prevail. It is often found in shaded understory locations where moisture and filtered light support its growth.
• Environment:  Naturally thrives in well-draining, organic-rich soils and high-humidity settings; typically grows in conditions that offer consistent moisture and stable, warm temperatures without direct, harsh sunlight.

Leaves

• Narrow, elongated leaves
• A smooth texture 
• Deep green coloration

Inflorescence (Spadix & Spathe)

• Consists of a compact spadix surrounded by a modest spathe
• Colors are generally subdued
• Does not produce a strong scent, its structure aids in attracting specific pollinators

Growth Habit

• Typically terrestrial
• May also exhibit epiphytic tendencies in its natural habitat
• Develops from a rhizome that supports the growth of its foliage

Light Requirements

• Bright, indirect light, mimicking the filtered sunlight of its native forest understory

Watering & Humidity

• Regular watering that keeps the soil consistently moist without waterlogging
• High humidity is essential for optimal growth

Soil & Potting Mix

• A well-draining, peat-based potting mix enriched with organic matter
• Containers with drainage holes help prevent root rot

Temperature & Fertilizer

• Ideal temperatures range from 65°F to 80°F
• Balanced, diluted fertilizer applied during the growing season supports steady growth

Division and Cuttings

• Most commonly achieved through rhizome division, which preserves the integrity of the plant
• Stem cuttings can also be used if nodes are present

Seeds

• Possible, but less common due to lower germination rates and longer time to maturity

Typical Issues

• Spider mites and mealybugs
• Occasional fungal infections due to overwatering

Treatment Recommendations

• Organic insecticidal soap for pests and ensuring proper watering practices to prevent root rot
• Chemical treatments should be used sparingly and as a last resort

• Prized for its elegant leaf structure and compatibility with modern interior designs, making it a favored choice for both personal and public green spaces

Wild Population Status

• Do not indicate immediate conservation concerns
• Habitat preservation remains important for tropical species

Market Availability

• Often regarded as a moderately rare addition to curated collections
