To make good potpourri, one needs to start with flowers that are dried or freeze-dried. The 3 basic factors one must look at when buying flowers to make a potpourri are: colour, texture and season appeal. Once these flowers have been thoroughly dried, start making your potpourri. Fresh flowers should NOT be used because they will have a mold & mildew smell, and, ultimately be tossed out.
