Last updated
You recognize Flowering Dogwood by its showy white (or pink) bracts appearing in spring before the leaves, creating the impression of delicate blossoms. This native understory tree reaches 15-25 feet with a graceful spreading form. The small red berries ripen in fall, and the leaves turn red-purple before dropping.
Flowering Dogwood performs best in partial shade with moist, well-drained, slightly acidic soils. Protect from hot afternoon sun and harsh winds. This tree requires consistent moisture during establishment. Prune minimally to develop natural form. Monitor for anthracnose and powdery mildew in humid conditions; improve air circulation and avoid overhead watering. This native provides multi-season interest.
