Deborah Griscom Passmore (1840–1911) was a botanical illustrator for the U.S. Department of Agriculture who specialized in paintings of fruit. Her work is now preserved in the USDA's Pomological Watercolor Collection, and she has been called the best of the early USDA artists. She rose to lead the USDA staff artists, and she became the most prolific of the group, contributing one-fifth of the 7500 paintings in the Pomological Watercolor Collection.

The U.S. Department of Agriculture's Pomological Watercolor Collection is an archive of some 7,500 botanical watercolors created for the USDA between the years 1886 and 1942 by around five dozen artists. Housed by the United States National Agricultural Library, it is a unique resource documenting existing fruit and nut cultivars, new introductions, and specimens discovered by USDA's plant explorers, representing 38 plant families in all. It has been called "one of the world's most unusual holdings of late 19th and early 20th century American botanical illustrations".
