Anthurium penningtonii Croat

• Genus: Anthurium
• Botanical Background: Described by Croat, this species emerged from intensive botanical surveys in neotropical regions. Its recognition reflects decades of work by taxonomists refining the classification of complex aroid lineages.

• Geographical Range: Native to tropical regions in Central and South America
• Environment: Thrives under conditions of high humidity and moderate temperatures; favors rich, well-draining organic soils in shaded understories, often growing as a terrestrial or occasionally epiphytic plant in disturbed forest clearings.

Leaves

• Large and elliptical 
• Glossy finish and prominently veined surfaces

Inflorescence (Spadix & Spathe)

• Modest spathe that may range from green to a soft reddish hue, accompanied by a spadix that supports small, numerous flowers
• Scent is not pronounced, its structure is adapted to attract specific pollinators

Growth Habit

• Exhibits a clump-forming growth with a modest, creeping rhizome
• Can be terrestrial or, in some cases, adopt an epiphytic habit, which is common in its native, humid forest environments

Light Requirements

• Bright, indirect light
• Direct sunlight may scorch the leaves, so filtered light is optimal

Watering & Humidity

• Regular watering to maintain consistently moist, yet not waterlogged, soil is key
• High ambient humidity is crucial; using a humidity tray or room humidifier can enhance its growth indoors

Soil & Potting Mix

• A well-draining potting mix enriched with organic matter is ideal
• A blend incorporating orchid bark and peat helps mimic its natural forest floor conditions, and a container with proper drainage is essential

Temperature & Fertilizer

• Warm temperatures ranging from 65°F to 80°F
• A balanced liquid fertilizer applied monthly can promote robust development

Division and Cuttings

• Primary method of propagation is via division of the plant’s rhizomes, a practice that is both simple and effective once healthy offsets become established

Seeds

• Requires controlled environmental conditions and patience, making division the favored technique for most cultivators

Typical Issues

• Spider mites and mealybugs
• Fungal root rot if overwatered

Treatment Recommendations

• Treatments such as neem oil or insecticidal soap are effective
• Ensuring the soil is not overly saturated and that the potting mix remains well-aerated can reduce the risk of fungal infections

• Stands out due to its intricate leaf structure and relatively understated floral display, making it a subject of interest not only for its beauty but also for its botanical uniqueness

• Prized in the ornamental plant trade for its rarity and unusual morphology
• Captivating foliage makes it a popular choice among collectors and a valued addition to indoor plant collections

Wild Population Status

• May be vulnerable to habitat loss like many tropical aroids

Market Availability

• Available through specialized nurseries and plant societies
• Relative rarity in the commercial market often makes it a sought-after specimen for dedicated collectors
