Why evergreen trees never lose their leaves?
A waxy coating on the needles also helps keep water from evaporating. These rolled-up, waxy needles resist cold and stay moist, which keeps them green throughout the winter. Evergreens' greater leaf longevity means they can survive in environments that don't work for their deciduous cousins.
How do evergreen trees survive winter?
Evergreens have thin needles with a waxy coating: adaptations that also reduce water loss! The outer bark of trees contains many air pockets, rather than living cells filled with liquid that can freeze. The air pockets in bark help provide insulation and protection against freezing and cracking during the winter.
