In botany, an evergreen is a plant that has leaves throughout the year, always green. This contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include:

• most species of conifers (e.g., hemlock, blue spruce, red cedar, and white/scots/jack pine), but not all (e.g., larch)
• live oak, holly, and "ancient" gymnosperms such as cycads
• most angiosperms from frost-free climates, such as eucalypts and rainforest trees
• clubmosses and relatives
