Anthurium sanguineum Engl.

• Genus: Anthurium
• Botanical Background: Described by Adolf Engler, the species has been the subject of botanical interest due to its unique aesthetic and its representation of tropical biodiversity in the Anthurium genus.

• Geographical Range: Indigenous to tropical rainforests in South America, where conditions are consistently warm and humid.
• Environment: Naturally thrives in shaded understory environments with high humidity, well-draining organic soils, and a stable, moist climate.

Leaves

• Large, heart-shaped
• Glossy and deep green
• The leaves sometimes display subtle red or purple accents along the veins

Inflorescence (Spadix & Spathe)

• Produces a compact inflorescence with a vibrant red spathe that surrounds the central spadix
• Although the spathe is not strongly scented, its striking color plays a role in attracting pollinators
  

Growth Habit

• Typically growing as a terrestrial plant
• Forms clumps with a rhizomatous structure that aids in natural propagation and stability in its native habitat

Light Requirements

• Prefers bright, indirect light; too much direct sunlight can lead to leaf scorch

Watering & Humidity

• Regular watering is essential to maintain evenly moist soil
• High humidity levels are beneficial for sustained growth
• Avoid waterlogging to prevent root rot
  

Soil & Potting Mix

• A loose, well-draining potting mix rich in organic matter is ideal
• A blend of peat, perlite, and orchid bark works well in containers equipped with drainage holes
  

Temperature & Fertilizer

• Between 65°F and 80°F
• Balanced, diluted fertilizer applied during the growing season

Seeds

• Less common due to slower germination rates
• When attempted, maintain a warm, humid environment to improve germination success
  

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if overwatered

Treatment Recommendations

• For pest control, insecticidal soap or neem oil is effective against most common pests
• To prevent root rot, ensure the potting mix is well-draining and avoid standing water

• The unique coloration and structure of Anthurium sanguineum have earned it a special place among tropical plant enthusiasts
• Its distinctive appearance also contributes to studies on the diversity of the Anthurium genus

• Prized for its dramatic dark leaves and vivid red spathe
• Its rarity and unique aesthetic make it a standout in both private collections and botanical displays
  

Wild Population Status

• While not currently classified as endangered, ongoing habitat loss in tropical regions poses potential challenges
• Conservation initiatives are focused on habitat preservation and sustainable cultivation
  

Market Availability

• Relatively rare in the commercial market
• A coveted addition for collectors and botanical gardens
