Photographed by Jim Fowler and designed by Ethel Kessler, the stamps celebrate orchid species that grow wild across the United States, from the California lady’s slipper to the marsh lady’s tresses found as far north as Delaware.
Each stamp features a photograph of one of these nine species: Cypripedium californicum, Hexalectris spicata, Cypripedium reginae, Spiranthes odorata, Triphora trianthophoros, Platanthera grandiflora, Cyrtopodium polyphyllum, Calopogon tuberosus and Platanthera leucophaea. The booklet contains 10 stamp designs and each design is featured twice for a total of 20 stamps. Triphora tranthophoros is featured on two stamps designs, to include the booklet cover.
