Sourwood trees grow 25 to 50 feet high with 12 to 20 feet of spread. Their leaves are dark green and appear to weep, with low-hanging branches. Sourwood trees have white flowers in summer and seed capsules that remain almost to winter. They start turning color in late August.
The sourwood tree's scientific name is Oxydendrum arboreum, and it belongs to the Ericaceae family. It is native to North America, and its wood is used to make handles and firewood. Sourwood trees are not susceptible to many pests or diseases. Fall webworm can remove leaves during the summer and fall, and twig blight can kill leaves at the tips of branches. Sourwood trees grow in full sun or partial shade, and they do well in well-drained soil.
