• Genus: Anthurium
• Botanical Background: First described by renowned aroid taxonomist Thomas Croat. Its distinctive morphology has contributed to a growing interest among botanists and collectors

• Geographical Range: Indigenous to the lowland tropical forests of Ecuador and possibly nearby regions in South America.
• Environment: Prefers consistent moisture and moderate temperatures typical of tropical climates; thrives in humid, shaded understory environments with rich, well-draining soils.

Leaves

• Broad, elliptical to lanceolate shape with a glossy finish
• Prominent dark venation that creates a striking visual contrast

Inflorescence (Spadix & Spathe)

• Spathe typically exhibits greenish to yellowish hues
• Compact spadix that supports clusters of small flowers

Growth Habit

• Generally terrestrial, growing from a robust rhizome system
• Forms clumps that help anchor the plant in its native forest floor

Light Requirements

• Bright, indirect light for optimal growth
• Tolerates moderate shade, making it suitable for indoor collections

Watering & Humidity

• Requires consistently moist soil without waterlogging
• Benefits from high ambient humidity, simulating its natural tropical habitat

Soil & Potting Mix

• Thrives in a well-draining, organic-rich potting mix
• Best suited for containers with ample drainage to prevent root rot

Temperature & Fertilizer

• Ideal temperature range is between 65°F and 80°F
• A balanced fertilizer applied during the growing season promotes healthy growth

Division

• Most commonly propagated by dividing the plant’s robust rhizomes
• Division helps maintain the species' genetic characteristics and vigor
  

Stem Cuttings (if applicable)

• Not a typical method for this species

Seeds

• Can be collected; however, germination tends to be slow
• Requires warm, humid conditions and patience during the germination process
  

Typical Issues
