UC Davis Professor Diane Ullman, left, and artist Donna Billick, co-directors of the Art-Science Fusion Program, display some of the ceramic design work that they contributed to the university's Nature's Gallery, due to be exhibited through summer at the United States Botanic Garden in Washington, D.C. These two tiles go with 128 others; all of them depict plants and insects found in the Ruth Risdon Storer Garden in the UC Davis Arboretum. Students, faculty, staff and community members crafted the tiles. They were packed in special crates last week and sent by truck to the nation's capital, where Billick and an assistant will assemble the mural as part of the botanic garden's installation called Celebrating America's Public Gardens, scheduled to run through Oct. 8. The exhibit is in two parts: A Sense of Place, with 12 participating gardens from around the United States; and Green Today, Greener Tomorrows, with eight participating gardens, including the UC Davis Arboretum.
