Yaupon is a small tree or large shrub native to the southeastern United States. It is known for its small, evergreen leaves and its small, white flowers that bloom in the spring. The tree produces small, black berries that are favored by a variety of birds. In the garden, yaupon is often used as a hedge or border plant due to its dense growth habit and its ability to tolerate trimming. In addition to its practical uses in the garden, yaupon has a long history of use by Native American tribes, who used the plant for medicinal purposes and as a source of caffeine. The leaves of the plant can be brewed into a tea that is similar in flavor to black tea.
