With rising living standards, potted flowers have become essentials for home and office decorations. Potted flowers instantly give a place the feel of life. For this newest set of postage stamps, the Directorate General of Posts has chosen three perennials: the Gloxinia (Sinningia speciosa), the African violet (Saint-paulia × hybrida) and the Flamingo flower (Anthurium scherzerianum). The three stamps have face values of NT$5.00, NT$12.00 and NT$19.00 respectively. The stamps were painted by Mr. Cheng Yuan-chun of the Department of Botany at the Taiwan Provincial Museum.:   Indoor potted flowers are species native to the forests of the tropics, sub-tropics and temperate regions. Even when there is insufficient natural light indoors, they can still grow lushly and flower with the help of artificial lighting. Many indoor potted flowers are Gesneriaceae, begonia and orchids. They are different from flowering plants that are grown outdoors and moved indoors right after flowering. With colorful and beautiful blooms, they are very well suited to grow indoors, or put on balconies or under eaves and trees.
