The ceremony was held in conjunction with the AmeriStamp Expo at the Mesa Convention Center, where DiPeri was joined by William J. Gicker, the Postal Service’s acting director of Stamp Services, and Ken Schultz, executive director of the Desert Botanical Garden in Phoenix, AZ.
Each Cactus Flowers Forever stamp depicts the floral display of one of these ten cacti: Opuntia engelmannii, Rebutia minuscula, Echinocereus dasyacanthus, Echinocereus poselgeri, Echinocereus coccineus, Pelecyphora aselliformis, Parodia microsperma, Echinocactus horizonthalonius, Thelocactus heterochromus and Parodia scopa. Cacti also may have common names, with some varieties having several different names in popular use.
The stamps are being issued in booklets of 20. These stamps will always be equal in value to the current First-Class Mail 1-ounce price. Within the booklet, each stamp design is featured twice. Art Director Ethel Kessler designed the stamps with existing photographs taken by John P. Schaefer.
Cactus flowers generally occur singly, although many separate blossoms might appear on a plant at the same time. Flowering occurs at different times of the year and even different times of the day or night. Most cactus flowers are large and flamboyant, with colors of white, red, pink, orange or yellow.
