Sorrel Tree Overview

The genus Oxydendrum is monotypic and thus contains just 1 species, O. arboreum. Native to North America, in the Appalachian mountains, this genus resides in the Ericaceae family. It is a deciduous shrub or tree with lance-shaped serrated leaves and white, bell-shaped flowers carried on an unbranched raceme and followed by small woody seed capsules. Commonly known as sorrel tree or sourwood, they are cultivated for their brilliant autumn foliage and prefer an acid soil in a sheltered position.
