Graptopetalum rusbyi,  rusby's stonecrop,
past and present

One of the goals of the Florilegium Program is to encourage contemporary artists to illustrate plants of the Sonoran Desert in order to draw attention to its unique flora and inspire efforts to conserve it. The Program hopes that artists will look beyond the more familiar plants and find equally fascinating but lesser-known specimens to illustrate.

One artist who has done exactly that is Carolyn Hitchcock. She has worked diligently in Margaret Pope’s “Drawing Plants for a Florilegium” class since its inception. One of the lesser known plants that Carolyn chose to illustrate is Graptopetalum rusbyi, or Rusby’s stonecrop.

This tiny plant was first described in 1883 by E.L. Green as Cotyledon rusbyi, giving credit to Dr. H. H. Rusby who had collected the plant near Clifton, Arizona. Twenty years later N.L. Britton and J.R. Rose placed the plant, with reservations, in the genus Dudleya. In 1920 Edward Bartram found the plant in Sabino Canyon, and, at Rose’s request, sent specimens to the New York Botanical Garden where it flowered in 1923. At this point Rose reclassified the plant as Graptopetalum rusbyi and described it in the journal Addisonia. The illustration accompanying Rose’s account was by Mary Emily Eaton, the highly skilled artist whose work greatly enhanced Britton and Rose’s The Cactaceae.

Carolyn recently completed the Nature Illustration Certificate at the Art Institute of the Arizona-Sonora Desert Museum. After a career of teaching seventh grade, answering emergency lines and police dispatching, all while running a private no-kill animal shelter, she wanted to do something different in retirement that would provide endless learning. Fortunately for the Florilegium Program, Carolyn found the Art Institute and botanical illustration. “A microscope and a plant exposed a whole hidden reality. Currently I am working on the chollas on my property. A simple task, I thought. Gleefully wrong!”

Contemporary botanical artists have been invited to enter the juried portion of the Florilegium Program’s upcoming exhibit, Botanical Art of the Sonoran Desert: Past and Present. The exhibit will be shown in the Ironwood Gallery and the Baldwin Education Building at the Arizona-Sonora Desert Museum from August 24 through October 27, 2013. — Cindy Hartwell
