Evergreen Trees are plants with leaves that always remain green throughout the duration of a year. Unlike deciduous trees that adapt for seasonal shifts by losing their foliage in the winter or dry seasons, evergreen trees never lose all of their leaves at a single regular moment—though they do shed their leaves gradually throughout the year to replace old leaves. Commonly found in tropical areas and warm arid environments, evergreen trees evolved to survive in regions with low nutrient levels. A large variety of evergreen trees exist and include most types and species of conifers, rainforest trees, eucalypts, oaks, hollies, cycads, and palms.
