Anthurium simpsonii Croat

• Genus: Anthurium
• Botanical Background: Described by the renowned botanist Thomas B. Croat, this species reflects ongoing efforts to catalog the rich diversity within the aroid family. Its discovery and subsequent study have contributed to a broader understanding of Anthurium evolution and diversity

• Geographical Range: Indigenous to tropical rainforests of South America. Its range is typically limited to regions where moist, shaded environments prevail
• Environment: Thrives in humid, warm conditions with well-drained, organic-rich soils. It is commonly found in the understory of rainforests, where dappled light and consistent moisture support its growth

Leaves

• Large, heart-shaped
• Glossy with a leathery texture
• Deep green color is accented by subtle venation patterns 

Inflorescence (Spadix & Spathe)

• Contrasting spathe and spadix
• Usually a vibrant hue, complementing the more subdued spadix, which plays a role in attracting specialized pollinators
• The scent is generally mild, contributes to the plant’s reproductive ecology

Growth Habit

• Epiphytic or terrestrial growth habit depending on its environment
• Typically develops a network of rhizomes rather than tubers, facilitating its spread in forested areas

Light Requirements

• Bright, indirect light
• Direct sunlight may scorch its leaves, while very low light can impede flowering and leaf development

Watering & Humidity

• Regular watering is key
• High humidity levels mimic its native habitat

Soil & Potting Mix

• A loose, well-draining mix rich in organic matter works best
• A blend including peat, perlite, and bark mimics the forest floor conditions favored by this species

Temperature & Fertilizer

• Maintain a warm environment with temperatures between 65°F and 80°F
• Balanced, water-soluble fertilizer applied during the growing season supports healthy development

Division and Cuttings

• Most commonly achieved through division of the rhizomes
• Stem or node cuttings may also be successful under controlled conditionss

Seeds

• Less common due to variable germination rates
• Require warm temperatures and consistent moisture to sprout, and are best sown in a sterile, fine-textured medium

Typical Issues

• Spider mites and mealybugs
• Occasional root rot

Treatment Recommendations

• Treat infestations with organic insecticidal soap or neem oil
• Ensure good air circulation to minimize fungal infections. Avoid overwatering to prevent root rot

• Drawn attention not only for its decorative qualities but also for its role in studies on tropical epiphyte adaptations
• Enthusiasts prize Anthurium simpsonii for its distinctive foliage and striking inflorescence

Wild Population Status

• Not extensively documented, localized habitat loss in tropical regions may pose conservation concerns

Market Availability

• Relatively rare in the commercial market
• Sought after by collectors and may be available through specialized nurseries or botanical institutions
