Anthurium erythrospadix Nadruz, Camelo & Temponi

• Genus: Anthurium
• Botanical Background: First described by Nadruz, Camelo, and Temponi, Anthurium erythrospadix was named for its distinctive red spadix (from "erythros," meaning red, and "spadix," referring to the flower spike). This species stands out among other Anthurium varieties due to its unique inflorescence.

• Geographical Range: Found primarily in the rainforests of Brazil
• Environment: Grows in humid, tropical climates with well-draining soil. It prefers a shaded or semi-shaded environment and requires high levels of moisture, making it suitable for rainforest conditions or cultivated environments with high humidity.

Leaves

• Large, dark green, and glossy, with a smooth, leathery texture
• Elongated shape with noticeable veins that run parallel

Inflorescence (Spadix & Spathe)

• Vibrant red spadix surrounded by a white to cream-colored spathe
• Inflorescence is visually striking, with a unique appearance that attracts both insect pollinators and horticultural enthusiasts alike

Growth Habit

• Epiphytic by nature but can also be grown terrestrially in well-draining soil. It has a rhizomatic growth pattern, allowing it to form clumps as it matures. Its growth habit is upright with a prominent spadix

Light Requirements

• Thrives in bright, indirect light
• Too much direct sunlight can cause leaf scorch, so a position that offers filtered light is ideal

Watering & Humidity

• Regular watering is crucial, with the soil kept moist but not waterlogged
• High humidity is essential for optimal growth
• Good candidate for humid indoor environments or greenhouses

Soil & Potting Mix

• A well-draining, peat-based mix is ideal for this species. It benefits from added organic matter to mimic the conditions of its natural rainforest habitat

Temperature & Fertilizer

• Prefers temperatures between 65–80°F (18–27°C)
• During the growing season, it benefits from a balanced liquid fertilizer applied monthly to encourage healthy foliage and flowering

Division

• Can be propagated by dividing the rhizome or taking stem cuttings with at least one node
• These cuttings can root in a humid environment with indirect light
  

Seeds

• Propagation is possible, it is less commonly used for this species due to the slow germination process
• If grown from seed, they should be kept in a warm, humid environment to encourage successful germination
  

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot is also a concern, especially if the plant is overwatered or if drainage is insufficient

Treatment Recommendations

• Insecticidal soap or neem oil can be used to control pests
• For root rot, ensure proper watering practices and use a well-draining potting mix
• Fungicides may be used in severe cases, but organic methods are often preferred
  

• Popular among horticulturists due to its unique aesthetic and its ability to thrive in high-humidity environments
• Often used in tropical gardens or as a striking indoor plant

• Prized for its vibrant spadix, which makes a beautiful contrast against its glossy leaves
• Often used in floral arrangements or as a statement piece in tropical plant collections

Wild Population Status

• Not considered endangered
• Habitat may be threatened by deforestation in its native Brazilian regions
• Conservation efforts aim to preserve the natural rainforests that support this species

Market Availability

• Specialized plant nurseries, particularly those that focus on tropical plants. It is less common in general markets, making it a rare find for collectors
