English holly is an invasive evergreen plant native to Europe that was introduced to North America as an ornamental plant. It outcompetes native plants for water and nutrients, reducing biodiversity. English holly can survive in various climates and reproduces quickly, allowing it to spread widely. Efforts are needed to control its population through removal and restricting its sale and planting.
