About the Flowering Dogwood
The flowering dogwood (Cornus florida) is the signature tree of the Tennessee spring landscape. From late March through April, its graceful, layered horizontal branches are covered in large white (or pink) bracts that signal the full arrival of spring – one of the most beloved floral displays in the eastern United States. It is both Tennessee's official state wildflower and one of the most widely planted ornamental trees in the South.
Flowering dogwood is native to Tennessee's forests, growing naturally as an understory species beneath taller hardwoods. In the landscape it excels as a small specimen tree, typically reaching 15 to 25 feet tall and wide, with a layered, architectural branching structure that is beautiful in all four seasons: spring flowers, summer green, rich red berries and burgundy fall foliage in autumn, and an elegant silhouette in winter.
Dogwood does require thoughtful siting in Nashville – it is sensitive to drought and intense afternoon heat, and is susceptible to dogwood anthracnose disease in poorly chosen locations. Planted correctly, however, it is a long-lived, rewarding, and ecologically valuable tree.
Identification
- Bark: Dark grayish-brown, breaking into small, blocky squares with age – sometimes described as "alligator-skin" texture.
- Leaves: Oval, 3 to 6 inches long with distinctive curved veins that parallel the leaf edge. Deep green in summer; burgundy to scarlet-red in fall.
- Flowers: The showy "petals" are actually four white bracts surrounding a cluster of small true flowers. Some cultivars have pink to rose-colored bracts. Bloom appears before or with the emerging leaves.
- Fruit: Clusters of glossy red drupes (berries), ¼ to ½ inch long, ripening September – October. Highly attractive to birds.
- Form: Low-branched, broadly spreading, layered horizontal crown – one of the most elegant and distinctive tree forms in the eastern forest.
Planting & Care in Nashville
Correct site selection is the single most important factor in successfully growing a flowering dogwood in Nashville.
- Sun and aspect: Dogwood performs best with morning sun and afternoon shade. An east or northeast-facing location is ideal. Intense afternoon sun in Nashville's hot summers stresses dogwood and increases disease susceptibility. Avoid planting on south or west exposures with full afternoon sun.
- Soil: Well-drained, moist, slightly acidic soil rich in organic matter. Dogwood does not tolerate waterlogged soil or highly alkaline conditions. Amend clay soils with compost at planting to improve drainage and organic content.
- Planting depth: Plant at the same depth as in the container or with the root flare visible. Deep planting is a leading cause of dogwood decline. Never bury the root flare.
- Mulch: A 3-inch layer of organic mulch over the entire root zone (from trunk to drip line) is essential. It retains moisture, regulates soil temperature, and protects the shallow roots from mowing damage.
- Watering: Dogwood needs consistent moisture. Deep watering during dry spells – especially the July – September heat – is important. Allow the soil to stay moist but never waterlogged.
- Disease management: Dogwood anthracnose is the most serious threat. Plant in good sun with good air movement, avoid overhead irrigation, and remove fallen leaves promptly in autumn. Avoid wounding the bark with lawn equipment.
Wildlife Value & Nashville Relevance
Flowering dogwood is one of the most ecologically productive small trees in Eastern North America. Its bright red, fat-rich berries ripen in September – October at exactly the right time to fuel migrating songbirds. More than 35 bird species consume dogwood berries, including American robin, bluebird, wood thrush, hermit thrush, cedar waxwing, and wild turkey.
In Nashville's natural forest understory, dogwood plays a vital role as a mid-story tree that connects the high canopy to the forest floor, providing habitat structure as well as food. Planting a flowering dogwood in your yard brings this ecological function into your neighborhood.
Tennessee's deep cultural connection to this tree – the state wildflower – makes it a meaningful planting for any Middle Tennessee homeowner who wants to express regional identity through their landscape.

Frequently Asked Questions
When do flowering dogwoods bloom in Nashville?
Flowering dogwoods typically bloom in Nashville from late March through mid-April, after redbuds and before the first leaves emerge fully. The bloom period lasts 2 to 4 weeks – cooler springs prolong the display while warm, windy springs shorten it.
How do I plant a dogwood correctly?
Plant in a location with morning sun and afternoon shade (east or northeast exposure is ideal), in well-drained, slightly acidic soil. Dig the hole 2 to 3 times wider than the root ball but no deeper than the root flare – planting too deep is the most common mistake leading to dogwood decline. Apply 3 inches of mulch over the root zone.
What is dogwood anthracnose and how do I manage it?
Dogwood anthracnose is a serious fungal disease that can kill flowering dogwoods in cool, moist, shaded sites. Symptoms include brown leaf spots, blighted shoots, and progressive crown dieback. Prevention focuses on good site selection: plant in sunny, well-ventilated locations, avoid overhead irrigation, rake and dispose of fallen leaves, and keep trees vigorous with proper watering and mulching.
Why is my dogwood not flowering?
Common reasons include insufficient sunlight, incorrect pruning timing (fall pruning removes flower buds), heavy nitrogen fertilization, or late frost damage to newly opened buds. Young trees planted from seed may take 5 to 7 years before heavy flowering – container-grown nursery trees flower sooner.
Is flowering dogwood good for wildlife?
Yes – flowering dogwood is an outstanding wildlife tree. Its bright red berries ripen in September – October and are consumed by more than 35 bird species, including American robins, bluebirds, wood thrushes, cedar waxwings, and wild turkeys. The fat-rich berries are particularly valuable to migrating birds building energy reserves.
