The fourth wedding anniversary is traditionally known as the fruit and flowers anniversary, according to About.com. More modern interpretations consider it an anniversary dedicated to gifts of appliances.
Because of the fruit and flowers theme for the fourth wedding anniversary, traditional gifts include bouquets of flowers, recreations of the bride's wedding bouquet and fruit baskets. If going the more modern route, possible gifts include kitchen appliances, hair grooming items and household appliances.
Traditionally, the first anniversary is known as the paper anniversary, the second anniversary as the cotton anniversary and the third as the leather anniversary. The idea of giving specific gifts tied to the year of an anniversary dates back to the Middle Ages.
