Evergreen, a plant that retains its leaves throughout the year. The term evergreen is usually used in describing trees and shrubs. Most evergreens are narrow-leaved and bear cones rather than flowers. Examples are spruce, hemlock, pine, and fir. Some evergreens are broad-leaved and bear flowers. Examples are mountain laurel, holly, and common myrtle.
Cinnamon, a tropical evergreen tree, related to the laurel. The bark is the source of a spice (also called cinnamon) and contains cinnamic aldehyde, an oil that is extracted and used as a flavoring, in medicine, and in perfume.
Thinking allows us to solve problems, plan ahead and defend ourselves from outside threats. It's what separates us from "lower" life-forms like plants, right? Well, maybe not.
