Anthurium erythrospathaceum Nadruz & Theófilo

• Genus: Anthurium
• Botanical Background: Described by Brazilian botanists Nadruz & Theófilo, Anthurium erythrospathaceum was named for its distinctive red-tipped spadix, as "erythro" refers to red, while "spathaceum" highlights the spathe's prominence.

• Geographical Range: Native to the tropical rainforests of Brazil
• Environment: Thrives in humid, shaded environments with high moisture. It naturally grows in well-draining, organic-rich soil, often found in the understory of tropical rainforests with diffused light.

Leaves

• Glossy, dark green, and elongated, with a leathery texture and well-defined veins running through them
• The shape is lanceolate, making them distinct in appearance

Inflorescence (Spadix & Spathe)

• Produces an eye-catching spadix, which is typically red or orange, surrounded by a creamy white spathe
• Spathe serves to protect the spadix during its development and is thought to help attract pollinators, including insects

Growth Habit

• Epiphytic plant but can also be cultivated terrestrially. It grows by developing rhizomes, and as it matures, it produces new shoots. The plant’s habit is upright, with large leaves that add to its ornamental appeal

Light Requirements

• Provide bright, indirect light
• Avoid direct sunlight, as it can scorch the leaves
• Shaded locations or indirect light near a window are ideal for healthy growth
  

Watering & Humidity

• Requires consistent moisture but should not be waterlogged
• Maintain high humidity, ideally between 60-80%, to mimic its tropical origins
• Regular misting and placing the plant on a humidity tray can help

Soil & Potting Mix

• A well-draining, peat-based mix with some perlite added is ideal
• The soil should retain moisture but also allow excess water to drain easily
• A mixture of orchid bark, sphagnum moss, and perlite works well

Temperature & Fertilizer

• Prefers temperatures ranging from 65–80°F (18–27°C)
• During the growing season (spring and summer), a balanced liquid fertilizer can be applied monthly to encourage growth

Division

• Can be propagated by dividing the rhizomes or taking cuttings that include a portion of the stem with a node
• These sections can be rooted in water or moist soil
  

Seeds

• Propagation is possible, it is less commonly used due to the slow germination process
• It is typically more effective to propagate through division or cuttings
  

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot can occur if the plant is kept in poorly draining soil
• Keep the plant in a clean environment
• Inspect for pests regularly
• Avoid overwatering

Treatment Recommendations

• Treat pests with insecticidal soap or neem oil
• If root rot occurs, remove the affected roots and repot in fresh, well-draining soil
• Use a fungicide in cases of fungal issues
  

• Appreciated for its ornamental value, especially its unique spadix and spathe
• Commonly used in tropical garden settings and as a striking houseplant

• Glossy leaves and vibrant inflorescence make A. erythrospathaceum a popular choice for decorative plant collectors
• Valued in tropical plant displays or as a statement plant in indoor environments

Wild Population Status

• No immediate concerns regarding the conservation
• Habitat destruction in parts of Brazil can pose a threat to its natural populations

Market Availability

• Somewhat rare in the market but can be found in specialized nurseries that focus on tropical plants or aroids
• Considered a collectible species due to its ornamental value
