Texas’ only caffeinated plant makes a buzzworthy tea - Texas Highways magazine.

 From the article:

“When we started harvesting a few years ago,” says Seibold, who now does most of the yaupon-gathering, “the fire damage was extensive. Now, I look for baby loblolly pine trees as I harvest, and I clear the yaupon out around them. It’s so good to see the young pines growing taller each time I go back. But there’s a seemingly endless supply of yaupon: Forest managers cut a 100-yard-wide firebreak last year through one of the ranches, and it’s already filled in with yaupon.”
