The winter interest of many trees includes interesting bark and sourwood doesn’t disappoint. As the tree matures the bark becomes gray, ridged and scaly. Pioneers used to chew sourwood bark for mouth pain, draw its sap to relieve fever and brewed leaf tea for digestive maladies. Today sorrel leaf tea is widely used to slake the thirst of mountain climbers.
