Definition - What does Evergreen mean?
Like the name suggests, evergreen plants refers to shrubs that never lose all of their leaves at the same time. Evergreen shrubs offer both structure and color regardless of the season.
Some shrubs actually turn green during the winter, with flowers blooming in spring and summer. Consequently, evergreens are commonly used as privacy borders or for hedges.
MaximumYield explains Evergreen
In botany, the evergreens differ from deciduous shrubs because they never lose all of their foliage during winter. Evergreen plants can either be shrubs or trees. Examples include, but are not limited to, Red Cedar, Blue Spruce, Hemlock, Cycads, Holly, Live Oak, Clubmosses, and Eucalypts, as well as different varieties of rainforest trees.
Homeowners often tend to invest in Box evergreens, which are consequently clipped or trimmed into hedges. In some cases, they can also be used to edge flower or vegetable beds and because they tolerate the shade very well, they can also grow underneath taller plants or trees. Since these evergreen plants grow to be quite thick, they are commonly used in topiary.
Other evergreen shrubs that are often used in gardens include Camellia, Lavender, Aucuba, and Fatsia.
