Deciduous tress do go into dormancy during winter months. Deciduous trees will start to lose their leaves in autumn. This process is called abscission.
Evergreen trees keep their leaves the year round. Some evergreens are broadleaf trees, and some conifers. And likewise with deciduous trees. Teak trees lose their leaves in the dry season. So you see it is quite variable.
well, pine trees are a type of tree that keep their leaves all year round. pine trees have leaves that are almost more like little needles but not as sharp. we normally use pine trees as Christmas trees. there are probably other trees that don't lose their leaves as well, and I'm sure there are some that don't lose leaves until late Autumn or early winter. hope it helps :D Evergreens.
