• Genus: Anthurium
• Botanical Background: Described by the botanist Croat, A. espinae is part of a diverse genus that includes many well-known ornamental plants. This species was named due to its distinctive spiny characteristics, a feature that differentiates it from other species in the genus.

• Geographical Range: Native to the rainforests of Central America
• Environment: Prefers high humidity and consistently warm temperatures, thriving in shaded areas with rich, well-drained soils. The conditions in its native habitat are typically moist and consistently warm, with an average temperature range of 70°F–85°F (21°C–29°C).

Leaves

• Elongated and lance-shaped, reaching lengths of up to 12–15 inches (30–38 cm)
• Glossy, dark green leaves feature pronounced veins, giving the plant a striking appearance

Inflorescence (Spadix & Spathe)

• Spadix is spiny and typically yellow or green, surrounded by a smaller, modified spathe
• Inflorescence stands out as it is relatively unique, with spiny projections that differentiate it from other species in the genus

Growth Habit

• An epiphytic species, meaning it naturally grows on trees or other structures in its native habitat
• It does not rely on soil for nutrients but absorbs moisture and nutrients through its roots from the air

Light Requirements

• Prefers bright, indirect light, mimicking the shaded conditions of the rainforest understory
• Direct sunlight can burn its delicate leaves, so it’s best to keep it in a location with filtered light or dappled shade

Watering & Humidity

• Requires regular watering, with the soil kept moist but not waterlogged
• High humidity is crucial, so placing the plant in a humidified room or using a humidity tray is ideal
• Misting the leaves can also help maintain humidity levels

Soil & Potting Mix

• A well-draining potting mix is essential, with a preference for mixes containing sphagnum moss, orchid bark, and perlite
• This helps provide the right balance of moisture retention and aeration for the roots

Temperature & Fertilizer

• Ideal temperatures for Anthurium espinae range from 70°F to 85°F (21°C to 29°C), with nighttime temperatures no lower than 60°F (15°C)
• During the growing season (spring and summer), feed with a balanced, water-soluble fertilizer every 4–6 weeks to encourage healthy growth

Division

• Most common method of propagation is through stem cuttings or division
• When dividing, make sure each section has roots and at least one leaf to ensure successful regrowth

Seeds

• Propagation by seed is possible, it is less common and can be time-consuming
• Germination can take several weeks and requires high humidity and warmth to ensure success

Typical Issues

• Spider mites, mealybugs, and aphids, which can damage the plant by feeding on its leaves
• Root rot can occur if the plant is watered excessively or if the potting mix does not drain well

Treatment Recommendations

• For pest control, apply insecticidal soap or neem oil to the affected areas
• To prevent root rot, ensure the plant is not sitting in stagnant water, and use a well-draining potting mix
• Removing damaged roots and repotting can help with recovery
  

• Unique and rare species, highly sought after by collectors for its unusual inflorescence and striking foliage
• Considered an example of the diversity found within the Anthurium genus, showcasing the broad range of forms the genus can take

• Enthusiasts prize Anthurium espinae for its decorative value, especially the combination of glossy, lance-shaped leaves and the distinctive spiny spadix
• Its ornamental appeal makes it a popular choice for indoor tropical plant displays

Wild Population Status

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

Market Availability

• Not widely available in mainstream nurseries but can be found in specialized plant shops or through dedicated plant collectors

• Relatively rare and highly prized in the aroid community
