A flower bouquet is a collection of flowers in a creative arrangement. There are different kinds including nosegay, crescent, and cascading bouquets. Flower bouquets are often given for special occasions such as birthdays or anniversaries. They are also used extensively in weddings. Traditionally the bride will hold the bouquet, and the maid of honor will hold it during the ceremony. After the wedding the bride will toss it over her shoulder, and it is believed that whoever catches the bouquet is the next in line to be married. This practice may be related to the Golden Apple of Discord myth.
Even before flower bouquets were used by brides in wedding they were used in a different form of art. They appeared as early as the 17th century and possibly earlier. Flower bouquets were captured in paintings and on pottery as decorations.
"The art of arranging flowers was first documented in the 17th century, when the Dutch, in particular, painted wonderful informal arrangements of flowers..."
"In the 18th century, arrangements were used to decorate the houses of the wealthy families and the aristocracy..."
In years past, as a matter of tradition, an upper class bride was required to hold a bouquet of roses or flowers as she walked down the aisle to prevent body odor from spreading and to drive away evil spirits.
