Dogwoods Bloom, Signal Spring

AUBURN, Alabama— The dogwood tree’s pink and white blooms signal the arrival of spring in the South. Dogwoods trees are features in many Alabama landscapes and celebrated in festivals throughout the region. The white flowering dogwood (Cornus florida), plentiful across Alabama, is an ornamental deciduous tree native to the eastern half of the United States.

10 Things to Know about Dogwoods

1. Dogwood trees sport white or pink flowers. However, the true petals are not the four colorful parts. The tightly packed, yellow cluster in the center form the real blooms. What appear to be petals are actually bracts, which is a type of leaf.

2. Flower color of the native dogwood is a creamy white. A naturally occurring variety of the native dogwood, Cornus florida rubra, has pink blooms. Many cultivated varieties are available in nurseries and landscape centers. Dogwood trees often appear in brilliant shades ranging from soft pink to deeper cherry reds. As a result, these showy bracts can attract pollinating insects to the flowers.

3. In addition, there are 17 species of dogwood native to North America. Gardeners are most familiar with the flowering dogwood (Cornus florida). According to Kerry Smith,  Master Gardener program coordinator for Alabama Extension, another common species is the Kousa Dogwood (Cornus kousa), or Chinese Dogwood. Kousa thrives in either full sun or shade and is much tougher than the flowering dogwood.

4. Many towns enjoy dogwood trees so much, they host annual parades or dogwood tours once the trees open their blooms in the early spring. North Carolina, Texas and Atlanta each host popular Dogwood Festivals each year. Vestavia Hills celebrates Alabama’s oldest Dogwood Festival and Trail.

5. Dogwood trees are often a preferred choice for planting because they are low maintenance once established. Smith said depending on the one you choose, it might be a short, stout bush or a 25-foot tall tree. If carefully treated, a mature dogwood tree may reach up to 30 feet in height.

6. Since native dogwoods grow in nature as understory trees, they prefer afternoon shade to shield them from blazing sunlight. According to Alabama Extension regional agent Sallie Lee, dogwoods are pretty versatile as a small tree. “It can be planted where larger-maturing trees would be a nuisance or a hazard,” said Lee. However, dogwoods still need room to grow. Lee advises planting dogwood trees at least 25 feet from structures to give the roots plenty of room to grow.

7. In the Southeast, the dogwood typically begins blooming in early March in the southern portion of Alabama and two to three weeks later in northern areas of the state. The bloom duration can last from two to four weeks.

8. Dogwood branches droop as the tree matures, and lower branches may need pruning to clear pedestrian or vehicle traffic.. Prune if needed any time after blooming. Alabama Extension regional Agent Mike McQueen said “since dogwoods bloom in early spring before May, wait until after they bloom to prune.”

9. Dogwoods have been used medicinally for generations. Since the bark is a rich source of bitter-tasting tannins, dogwood leaves often treated pain, fevers, backaches, dizziness, or weakness. According to McQueen, “dogwood bark was one of many barks used as a fever medicine before quinine came into general use.” Tea made from the bark was used to treat pain or fever.

10. Blooming by Easter, the tree and its flowers have inspired legends of their part in the crucifixion of Jesus Christ. Legend says that the bracts of the dogwood are set in the shape of a cross and bear nail marks of the Crucifixion, while the red leaves in autumn point to Jesus’s blood on Calvary.
