Flowering Dogwood, Cornus florida, is perhaps the most beloved native flowering tree. Flowering Dogwood grows throughout Eastern North America in rich, acidic woods in full sun to part shade. The tree grows from 15 to 30 feet tall and wide, with a somewhat flattened top. Bloom time is early spring. Flowers are followed by red berries, which birds enjoy. The foliage turns an attractive red color in autumn. Best grown in humus-rich, acidic soils in part shade.
