Why don't some trees lose their leaves in the fall?

Browse → Nature → Plants
As the weather begins to get colder in the fall, you may notice the leaves on the trees outside changing color and dropping to the ground. But what about the trees that stay green and leafy, even during the winter?   

These special trees, which include pines, cedars, spruces, and firs, are called evergreen trees. Their leaves are able to stay on the branches in the winter because they have special protection from the cold!

Often thin like needles, evergreen leaves are covered with a thick wax, and their insides hold materials that help them not to freeze. There’s no need for evergreens to shed their leaves, because these leaves are strong enough to survive the chill of winter. Some may even continue to make food at a slower pace during this cold time!
