In 2017, the U.S. Postal Service introduced the Green Succulent stamp, which is a Forever stamp for international mail. This Global Forever stamp allows the mailing of a one-ounce letter to any country where First-Class Mail International service is available.

The Green Succulent stamp has a postage value equivalent to the price of a single-piece First-Class Mail International first-ounce machineable letter at the time of use. The stamp features a photograph of an echeveria plant, showcasing its unique beauty.

The photograph is taken from an aerial perspective, providing a close-up view of the intricate rosette pattern formed by the leaves of the echeveria plant. Echeveria is a genus of succulent plants that belongs to the stonecrop family (Crassulaceae). With over 140 species native to the Americas, echeverias are known for their ease of propagation and hybridization, resulting in a wide variety of selections available to gardeners and collectors.

Most echeverias grow in a rosette pattern, resembling a circular arrangement of leaves similar to a rose. The leaves exhibit variations in size, texture, and color, ranging from blue, pink, and purple to red. Echeverias produce flowers of different colors, including cream, yellow, orange, red, and pastel pink, which bloom on tall arching stalks. The flowers typically open sequentially rather than all at once, with new buds appearing while others are fading. The blooming cycle can extend over several weeks.

Echeverias are popular choices for rock and container gardening, and they are frequently incorporated into indoor dish gardens. They offer an attractive and versatile option for plant enthusiasts.

The art director for the Green Succulent stamp was William J. Gicker, while the designer and typographer were Greg Breeding. The stamp design features an existing photograph by Erika Kirkpatrick, chosen to capture the essence of the echeveria plant.
