Yaupon is a small evergreen holly tree native to the coastal plain of the southeastern US, especially common in maritime forests. Yaupon is also widely naturalized in the Piedmont, particularly in the Durham area, and usually occurs at the edges of woods. Durham, NC 4/14/2011. | |
The small, elliptic leaves are thick, have crenate margins, and are glossy above. The young leaves contain caffeine and may be used to make a delicious tea, which is comparable to the yerba mate (Ilex paraguariensis) that Argentinians drink in copious amounts. The tea is a fine drink — don't be put off by the scientific name vomitoria, which refers to the effect of drinking gallons of tea at a sitting (as was done during purification rituals) or eating its fruits. Read a historical account of the tea use from John Lawson below. Durham, NC 4/14/2011. | |
The fruits, which technically are drupes, not berries, are bright red and last through the winter. The fruits are emetic. Austin, Travis Co., TX 4/29/2011. | |
