evergreen
An evergreen is a plant that retains its leaves all the year round, although they are continually being shed and replaced. Evergreens are divided into two groups: narrow-leaved (conifers) and broad-leaved. Conifers, include fir, spruce, pine, and juniper. Among the broad-leaved evergreens are holly and rhododendron. Not all conifers are evergreens; exceptions are the deciduous larch (Larix) and dawn redwood (Metasequoia). Compare with deciduous tree.
