Anthurium cirinoi Croat

• Genus: Anthurium
• Botanical Background: Described by renowned botanist Thomas B. Croat, who has contributed significantly to the understanding and classification of the Anthurium genus. Croat’s work in the early 1980s helped categorize many species from the region.

• Geographical Range: Primarily found in Central America, with specific occurrences in Panama and Costa Rica. It grows in the humid, mist-laden cloud forests of these areas, typically at elevations of 1,000 to 1,500 meters.
• Environment: Thrives in high-humidity environments with ample rainfall and moderate temperatures. Prefers well-draining, acidic soils, often found in the rich, organic forest floors of its native range.

Leaves

• Large, heart-shaped, and glossy, with a deep green color
• Can grow up to 40 cm in length
• Have a leathery texture, which helps them retain moisture in their native, humid environment

Inflorescence (Spadix & Spathe)

• Consists of a typical Anthurium spadix, which is white and slightly curved
• The spathe is green, transitioning to white or cream as it matures
• Has a subtle fragrance that attracts pollinators such as flies and beetles

Growth Habit

• Terrestrial species that forms a rosette of leaves, similar to many other Anthurium species
• Grows from a rhizome and does not climb or vine, which differentiates it from epiphytic relatives

Light Requirements

• Thrives in bright, indirect light
• Direct sunlight can scorch its leaves, so filtered light or dappled shade is ideal

Watering & Humidity

• Regular watering is required, with a preference for consistently moist soil
• Requires high humidity, ideally 60% or higher

Soil & Potting Mix

• A well-draining, rich potting mix with organic material, such as peat moss or coconut coir, is ideal
• Best suited for a container that allows for some root expansion but prevents waterlogging

Temperature & Fertilizer

• Prefers temperatures between 18°C and 27°C (65°F to 80°F)
• Balanced, water-soluble fertilizer should be applied monthly during the growing season, particularly in the spring and summer

Division

• Most common method of propagation is through division of the rhizome
• Careful separation of the plant’s sections, ensuring each division has roots and a few leaves, can be effective
  

Stem Cuttings (if applicable)

• Not Applicable

Seeds

• Less commonly used in cultivation due to the slow germination process. Seeds require warmth, humidity, and time to develop

Typical Issues

• Common pests include spider mites, aphids, and mealybugs
• Over-watering can lead to root rot, while low humidity levels may cause the leaves to become dry and brittle

Treatment Recommendations

• Use insecticidal soap or neem oil for pest control
• Ensure the plant is not waterlogged and that it receives good air circulation to prevent fungal diseases
• If root rot occurs, trim affected roots and repot in fresh, dry soil
  

• Named after the botanist Thomas B. Croat, who identified and described it in the wild
• Its striking, large leaves are prized in ornamental horticulture

• Valued for its impressive, heart-shaped leaves and ability to thrive in conditions that mimic a tropical cloud forest
• A popular choice for plant collectors and interior decorators

Wild Population Status

• While not currently listed as endangered, habitat destruction in Central America could pose a threat to wild populations
• Conservation efforts in tropical cloud forests are vital to protect these habitats

Market Availability

• Relatively rare in cultivation, primarily available through specialized nurseries or collectors
• Not as widely found in mainstream markets due to its specific environmental requirements
