Dried flowers are simply flowers that have been preserved by removing their moisture content through various drying methods. Drying flowers is a popular way to preserve them for long periods of time, especially if you want to use them for decoration, crafts or other purposes.
There are several ways to dry flowers, including air-drying, using desiccants like silica gel, pressing them between heavy books, or using a microwave oven. Some popular types of flowers that are often dried include roses, lavender, chamomile, hydrangeas, and many others.
