The Nature of Evergreen Christmas Trees
Christmas trees belong to the coniferous evergreen family, meaning they keep their needles green throughout all seasons. Unlike deciduous trees that shed leaves annually, evergreens maintain their foliage year-round through a remarkable biological process.

Why Christmas Trees Stay Green Year-Round
These magnificent trees evolved special adaptations to survive harsh winters. Their needles contain high levels of chlorophyll and special waxes that protect them from freezing temperatures.
“Evergreen trees have developed specialized needle-like leaves that resist cold and moisture loss, allowing them to photosynthesize even during winter months.” – Dr. Sarah Thompson, Botanist
