Anthurium nelsonii Croat

• Genus: Anthurium
• Botanical Background: Described by renowned aroid taxonomist Thomas Croat, whose extensive work in the field has greatly advanced our understanding of Anthurium diversity.

• Geographical Range: Native to the tropical rainforests of Central America, Anthurium nelsonii is typically found in moist, shaded understories where environmental conditions are optimal for its growth.
• Environment: Warm, humid microclimates with well-draining, organic-rich soils and consistent moisture, often occurring in lowland rainforest or cloud forest conditions.
