Anthurium pirrense Croat

• Genus: Anthurium
• Botanical Background: Described by renowned aroid specialist Thomas Croat, this species adds to the diverse legacy of Anthurium research. 

• Geographical Range: Native to tropical regions, where it is typically found in lowland to montane rainforests.
• Environment: Thrives in warm, humid conditions with well-draining, organically rich soils. It is generally found in shaded forest understories where diffused light and consistent moisture support its growth.

Leaves

• Large, heart-shaped
• Glossy texture with subtle variegation

Inflorescence (Spadix & Spathe)

• Delicate spathe
• Tones ranging from creamy white to soft pink—surrounding a slender spadix
• Scent is typically mild or absent

Growth Habit

• Terrestrial, developing from creeping rhizomes that allow it to form clumps
• Sometimes exhibit semi-epiphytic tendencies

Light Requirements

• Provide bright, indirect light
• Direct sunlight should be avoided as it can scorch the leaves

Watering & Humidity

• Maintain consistently moist soil conditions without waterlogging
• High humidity is essential
• Humidifier or placing the plant in a naturally damp area

Soil & Potting Mix

• A well-draining, peat-based potting mix with added perlite or orchid bark
• Container with adequate drainage

Temperature & Fertilizer

• Range from 65°F to 80°F (18°C to 27°C)
• Fertilize lightly during the growing season with a balanced, diluted fertilizer

Division

• Most commonly achieved by dividing the rhizomes during repotting
• Ensure each division includes at least one growing point to promote successful establishment

Seeds

• Less common due to variable germination rates and the specialized care required during the seedling stage

Typical Issues

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

Treatment Recommendations

• Insecticidal soap or neem oil
• Reduce watering and apply a fungicide suitable

• Garnered attention due to its limited natural distribution and the expertise required for its cultivation
• Prize for its unique combination of bold foliage and understated inflorescence

• Rarity and aesthetic appeal make it a coveted addition to specialized indoor collections and botanical gardens

Wild Population Status

• Detailed conservation assessments are limited, suggests that it is vulnerable to habitat loss and environmental changes
