Preserved flowers are also called perpetual flowers, eco-flowers, and “never dying flowers”. Perennials are dried flowers made from fresh cut flowers such as roses, carnations, phalaenopsis orchids and hydrangeas, which are processed through a series of complex processes such as dehydration, decolorization, drying and dyeing. The color, shape, and feel of perennials are almost the same as those of flowers, and they maintain the qualities of flowers with richer colors and higher usage.
