I had considered growing blueberries in the past, but they suposedly need slightly acidic soil and I never bothered to try to set that up. But recently I was reading that tea plants (Camellia sinensis ) also like acidic soil and some shade. So I decided it might be fun to try growing some blueberries interspersed with tea plants, the blueberries would shade the tea plants. I got some of both plants and added some peat moss to the dirt around them. Will see how it works out. Has anyone else tried this?
Also got a yaupon holly (Ilex vomitoria) the only native North American plant (and native to Texas) that contains caffine. Tea can also be made from their leaves. Yerba mate is the caffine producing South American relative of yaupon.
