Yaupon Drink Photos
GAINESVILLE, Fla. —In this photo released by the University of Florida’s Institute of Food and Agricultural Sciences, Matt Palumbo, a master’s graduate, cooks yaupon (YO-ponn) holly branches prior to steeping them in hot water to make a beverage, in a garden on the UF campus in Gainesville on Tuesday, June 23, 2009. Yaupon is the only U.S. native plant that produces substantial amounts of caffeine. Palumbo co-wrote a scientific paper showing that nitrogen fertilizer increases yaupon’s caffeine content.
