Adelonema erythropus (Mart. ex Schott) Schott

• Genus: Adelonema
• Botanical Background: The species was first described by Martius and Schott, and Schott later formalized its current name. The genus Adelonema was established in the early 19th century, with this species recognized for its distinct appearance.

• Geographical Range: This species is primarily found in the Amazon rainforest and other tropical regions of South America, thriving in areas with consistent moisture and high humidity.
• Environment: Adelonema erythropus grows in shaded, humid environments, often found on the forest floor or in partially shaded understory areas. It prefers a warm, moist climate with high levels of humidity, and it requires well-drained, fertile soil.

Leaves

• Large, elongated blades with a glossy green surface

• Striking red petioles that provide bold contrast against the foliage

• Known for its lush, dramatic appearance in tropical displays

Inflorescence (Spadix & Spathe)

• Typical aroid structure with a pale green or white spathe and a yellow to cream-colored spadix

• Not as showy as other aroids, but still adds botanical interest

• Subtle yet elegant inflorescence appreciated in cultivated settings

Growth Habit

• Terrestrial growth habit anchored by a rhizome

• Does not exhibit climbing or epiphytic behavior

• Grows in a grounded, upright manner ideal for understory planting

  
  

Light Requirements

• Prefers bright, indirect light

• Avoids direct sun exposure, which can scorch its leaves

Watering & Humidity

• Keep soil consistently moist but not waterlogged

• Thrives in high humidity environments

• Regular misting or use of a humidifier is beneficial indoors

Soil & Potting Mix

• Well-draining, fertile aroid mix (peat, perlite, and bark)

• Use containers with proper drainage to prevent root rot

Temperature & Fertilizer

• Optimal temperature range is 70–85°F (21–29°C)

• Apply a balanced liquid fertilizer every 4–6 weeks during active growth

Division

• Propagation is typically done by dividing the rhizome, ensuring each section has at least one node and healthy roots

Stem Cuttings (if applicable)

• Can also be propagated through stem cuttings, ideally with one or more nodes for optimal rooting success

Seeds

• Rarely used; requires steady warmth and moisture, with slow germination not ideal for most home growers

Typical Issues

• Spider mites, aphids, and mealybugs can appear in low-humidity or stressed environments

• Root rot is a risk in overly wet or poorly draining soil

Treatment Recommendations

• Use insecticidal soap or neem oil to treat pest infestations

• Improve drainage and avoid overwatering to prevent root rot

• Apply fungicides if rot symptoms persist

• Admired for its ornamental value and striking appearance

• Highly prized by collectors of rare aroids, though not widely known outside enthusiast circles

• Red petioles and large glossy green leaves add vibrant contrast and texture

• Perfect for tropical-themed indoor gardens and decorative plant displays

Wild Population Status

• No major conservation concerns currently reported

• Ongoing habitat loss in the Amazon could impact wild populations over time

  
  

Market Availability

• Occasionally available through specialty aroid nurseries and tropical plant collectors

• May be rare in mainstream markets and could require searching or importing for some regions
