Why do Evergreen stay green all year round?
Evergreen trees (also known as conifers because of the cones that hold their seeds) include spruce, fir and pine trees. Deciduous trees like maples, oaks, etc. loose all their leaves at about the same time. Evergreens do not. They are able to make new leaves before the old ones fall off. Some evergreens can keep their leaves a few years before they fall off!
Evergreens have adapted to live in climates where there may be limited annual sunshine and/or available water. They thrive in cold climates like Michigan. The evergreen leaves look like needles. Botanists discovered that the needles are actually regular leaves that are rolled up very tightly and have a very waxy coating. This shape allows the evergreen to conserve water during the summer and winter months.
