The eleventh day of Christmas (Jan 4th) is Evergreen Day. An evergreen tree is a tree that has leaves in all seasons. This contrasts with deciduous trees which completely lose their foliage during the winter or dry season.
The term “evergreen” can refer metaphorically to something that is continuously renewed or is self-renewing. One example of metaphorical use of the expression is the term “Evergreen content” used to describe perennial articles or guides about topics that do not change frequently.
On the Internet, evergreen is a term used by some ad agencies to describe a Web site that is updated on a daily or other frequent basis. A Web site that is evergreen is considered more likely to attract both first-time and repeat visitors.
In magick, evergreens are considered to have a cleansing, and revitalizing power. The aroma of evergreen trees reinvigorates and replenishes psychic and magical energy.
