If you're hoping to preserve flowers for longer than the few days they last fresh, you're in luck. Preserving flowers by drying them is simple, but a long process, taking anywhere from 10 to 20 days. Most annuals, perennials, wildflowers and even herbs are suitable for drying. Some flowers, such as asters, marigolds, dahlias, roses and sunflowers, are better dried in a desiccant, a chemical that draws moisture from the flower.
Place the stems of the flowers together with the ends meeting. Cut a piece of twine and wrap and tie it around the stems of the flowers, leaving enough twine to hang the flowers from.
Tie the end of the twine to a hook in a dark room, hanging the flowers upside down. Ideal drying rooms include attics, pantries and closets; basements and garages have too much moisture and will prevent adequate drying.
Hang the flowers until all moisture evaporates. The drying process may take two weeks or longer. Flowers are dry when they feel crisp.
Display dried flowers in a vase. To store, wrap dried flowers in newspaper and place them in a shoe box with small holes pierced through all sides to permit air circulation.
