Anthurium prominor Croat

• Genus: Anthurium
• Botanical Background: Described by the renowned botanist Thomas B. Croat, whose work has greatly contributed to the modern understanding of the Araceae. His research helped clarify relationships within Anthurium and placed emphasis on detailed morphological features.

• Geographical Range: Indigenous to parts of Central and South America.
• Environment: Flourishes in high-humidity conditions with well-draining, rich, organic soil; often grows under the canopy, benefiting from diffused light and a stable, warm temperature range.

Leaves

• large, heart-shaped
• Exhibit a glossy texture
• Deep green hue

Inflorescence (Spadix & Spathe)

• Prominent spathe that may display vibrant shades against a contrasting spadix
• Not particularly fragrant, the structure is adapted to attract specialized pollinators through visual cues

Growth Habit

• Has a terrestrial growth habit with a well-developed rhizome system that supports sustained growth
• Does not typically exhibit climbing or epiphytic tendencies

Light Requirements

• Bright, indirect light
• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• A well-draining, peat-based potting mix enriched with organic matter is ideal
• Containers with drainage holes are necessary to prevent root rot

Soil & Potting Mix

• A well-draining, chunky aroid mix (bark chips, perlite, and peat or coco coir)
• Good aeration helps prevent root rot

Temperature & Fertilizer

• Grows best within a temperature range of 65°F to 80°F
• A balanced liquid fertilizer applied during the growing season supports healthy growth without overfeeding

Division

• Most commonly achieved through rhizome division

Stem Cuttings (if applicable)

• Node cuttings may also be used to develop new plants

Seeds

• Less common; requires a warm, humid environment to ensure proper germination and development

Typical Issues

• Spider mites and mealybugs
• Root rot may occur if watering practices are not carefully managed

Treatment Recommendations

• Insecticidal soap for pest control
• Ensuring proper drainage to prevent fungal infections

• Noted for its impressive foliage and its role in tropical ecosystem
• Distinct appearance has led to interest among collectors and botanists alike

• Prized for its bold leaf structure and elegant inflorescence
• Adds a touch of the exotic to indoor plant collections and is often showcased in specialty plant exhibitions

Wild Population Status

• Faces threats from habitat loss due to deforestation

Market Availability

• Relatively rare in the commercial market and tends to be sought after by collectors and botanical enthusiasts
• May be available through specialized nurseries or plant societies
