Anthurium calimense Croat & D.C.Bay

• Genus: Anthurium
• Botanical Background: Described by renowned botanists Croat and D.C. Bay, this species adds to the rich diversity of Anthurium. Their research has significantly contributed to modern aroid classification.

• Geographical Range: Native to tropical regions of South America. It is most often encountered in humid, lowland rainforests.
• Environment: Thrives under consistently moist conditions with partial shade. Favors well-draining soils rich in organic matter and benefits from the stable, warm climate of its native habitat

Leaves

• Typically heart-shaped or lanceolate
• Glossy texture and deep green color
• May show subtle venation patterns

Inflorescence (Spadix & Spathe)

• Produces a vivid spathe that may range in color from green to red
• Accompanying spadix is compact and serves as an important attractant for pollinators
• Flower structure has evolved to suit specialized pollination strategies

Growth Habit

• Primarily terrestrial, growing from a creeping rhizome that supports a moderate plant size

Light Requirements

• Does best with bright, indirect light
• Direct sunlight can be too intense and may harm its foliages

Watering & Humidity

• Regular watering is essential
• High humidity is beneficial and helps maintain optimal growth conditions

Soil & Potting Mix

• A light, well-draining potting mix that is rich in organic matter is ideal
• Containers with proper drainage will prevent waterlogging and support healthy root development

Temperature & Fertilizer

• Maintain temperatures between 65°F and 80°F
• Balanced fertilizer applied during the growing season can promote robust growth without overfeeding

Division

• Dividing the rhizomes
• Reliable and helps maintain the genetic traits of the parent plant

Stem Cuttings (if applicable)

• Not Applicable

Seeds

• Less common due to slow germination and lower success rates compared to vegetative methods

Typical Issues

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

Treatment Recommendations

• Use organic insecticides and improve air circulation to control pest issues
• For fungal infections, adjust watering practices and consider safe chemical treatments if necessary

• Noted for its unique evolutionary path within the Anthurium genus
• Specialized pollination mechanisms contribute to its ecological role in native habitats

• Prized for its unusual inflorescence and striking foliage
• A valued specimen in specialized aroid collections and tropical plant displays

Wild Population Status

• There is limited data on the wild population status of Anthurium calimense
• Habitat loss in tropical regions may pose a risk to its natural occurrence
  

Market Availability

• Considered rare and is typically found among specialist growers and in curated plant collections rather than in mainstream nurseries
