I picked these flowers this morning from my garden and put them in a pitcher to welcome Autumn. Mums are great at this time of the year. I stuck some old dried flowers in between them. To dry the flowers, first I hang them up side down and wait until they are air dried and then I put them in a vase without water. When I am making arrangements I can place them between fresh flowers. Depending on its species they could last for a year or more without loosing their general characteristics.
