Oxydendrum arboreum, or sourwood, is a native ornamental shade tree near Ontario, known for its year-round visual appeal. It thrives in acidic, moist, well-drained soils and is drought-tolerant with long blooming periods. While it generally faces few disease or pest issues, it can be sensitive to pollution, soil compaction, and root disturbance, making it best suited for less urbanized areas. Sourwood is slow-growing and not tolerant of transplantation, so it�s best moved when young and through containers in spring. Though somewhat messy with fallen leaves, fruit clusters, and some flower debris, it adds charm to landscapes.
