DENDROLOGY

Detailed explanation-1: -But why do evergreen trees remain green all year? Evergreens have very strong leaves that are rolled up as long, thin needles. This special needle shape, along with a waxy coating, allows the evergreens to conserve water during summer and winter, which is needed for that continued photosynthesis process.

Detailed explanation-2: -While it’s true that the majority of conifers are evergreen (they retain foliage for a full year or more), the word “conifer” is not synonymous with “evergreen.” There is a small group of conifers that grow and drop a new set of leaves every year, just like maples, birches, or other deciduous trees.

Detailed explanation-3: -Evergreens are trees that stay green year round. While deciduous tree leaves change color, and then drop to the ground as the trees go into their winter dormancy, evergreen trees appear to just keep growing.
