Pothos
Epipremnum aureum, commonly known as pothos, golden pothos, or devil's ivy, is a species of flowering plant in the arum family (Araceae). Native to the Society Islands in the South Pacific, it is an evergreen, herbaceous perennial vine that climbs using aerial roots along tree trunks and rocks in its natural habitat.[1] The plant features glossy, heart-shaped leaves that are typically 3 to 6 inches long and wide, bright green or variegated with irregular splashes of yellow, cream, or white; juvenile leaves remain smaller and entire, while mature foliage can reach up to 3 feet in length with fenestrations along the midrib.[2] In the wild, stems can extend up to 65 feet, forming dense colonies, though it rarely flowers or fruits in cultivation.[2] Widely popular as a low-maintenance houseplant, Epipremnum aureum thrives in a range of conditions, including low to bright indirect light, temperatures between 60°F and 80°F, and moderate humidity, making it suitable for indoor environments worldwide.[3] It prefers well-drained soil and should be watered when the surface dries to prevent root rot, with fertilization applied every two weeks during active growth and monthly in winter using a balanced houseplant formula.[3] Propagation is straightforward via stem cuttings in spring or summer, often rooting in water or moist soil, or through layering with aerial roots; repotting annually in a soilless mix helps maintain vigor.[3] Valued for its trailing or climbing habit, it is commonly grown in hanging baskets, on moss poles, or as ground cover in tropical landscapes, and studies indicate it effectively removes indoor air pollutants such as formaldehyde, benzene, and xylene.[2] Despite its ornamental appeal, Epipremnum aureum is toxic to humans and animals if ingested, containing insoluble calcium oxalate crystals that cause intense oral irritation, swelling, vomiting, and difficulty swallowing; skin contact with the sap may also lead to dermatitis.[1] In suitable climates (USDA zones 10-12), it persists as a perennial but requires protection from direct sun to avoid leaf scorching.[2] Common pests include mealybugs, spider mites, and scale, managed through cultural practices or insecticidal soap, while overwatering often results in yellowing leaves or drooping.[2] Outside of controlled settings, Epipremnum aureum has naturalized in tropical and subtropical regions, including parts of Florida, where it is classified as a Category II invasive species by the Florida Exotic Pest Plant Council due to its ability to form dense mats that smother native vegetation in hammocks and disturbed areas.[4] Its ease of propagation and escape from cultivation contribute to ecological concerns in such environments, though it remains a staple in global horticulture for its resilience and aesthetic versatility.[5]Taxonomy and nomenclature
