Sourwood is a slow-growing flowering tree, hardy in USDA zones 5-9, that matures to about 20-50 ft × 10-25 ft. It does best in full sun and part shade with medium water needs in well-drained, moist and occasionally-dry soil. Expect cream and white blooms in summer. It attracts bees, butterflies and pollinators, stands up well to deer, dry soil and fire.
