Thats awesome, just read up on the Yaupon Holly as a tea plant. Used to see this on a rare occasion working for the Forest Service in AL, thought it made a beautiful ornamental.
Surprised that its on par with Guayusa and Yerba Mate in terms of tea quality, antioxidants, etc.
If anyone has a small plant or a handful of Yaupon cuttings, I'd be glad to trade.
