Most evergreen trees are gymnosperms.
Evergreen is a perennial woody plant with green leaves all year round. Evergreen leaves don't die forever, but they live longer than deciduous trees. For example, Hollyleaf can live 1 ~3 years, pine leaves can live for 3 ~5 years, and Podocarpus leaves can live for 2 ~8 years. Evergreen trees grow new leaves every spring, and some old leaves fall off, but the stems keep green leaves all the year round, so they are called evergreen trees.
Evergreen trees refer to woody plants with green leaves and large plant types all year round. Some evergreen trees grow new leaves before the old leaves fall off. Give people a feeling of not falling leaves. The leaf life of these plants is two or three years or longer, and new leaves grow every year. When new leaves grow, some old leaves fall off. Because they are updated one after another, they can keep the four seasons evergreen, such as Zizyphus jujuba, Pinus bungeana and Korean pine. This kind of plants are often regarded as the first choice for greening because of their evergreen characteristics and high ornamental value. For example, Pinus bungeana is the most common evergreen tree, which we often see in parks, courtyards, squares and schools.
