Flowering dogwood (Cornus florida) and eastern redbud (Cercis canadensis) are two of the most striking spring-blooming understory trees in eastern North America. They often bloom simultaneously and share a similar size range and habitat, which leads to confusion — especially from a distance, when both appear to be clouds of white or pink flowers in the woodland edge. Up close, however, the two trees are not closely related and their features are quite different.

Flower identification

Flowering dogwood (Cornus florida)

What most people call "dogwood flowers" are technically bracts — modified leaves that surround the true flowers. Per NC State Extension, each apparent "flower" consists of four white (occasionally pink) bracts, each with a distinctive notch at the tip, surrounding a tight central cluster of 20–30 tiny, true yellow-green flowers. The bracts serve to attract pollinators to the small true flowers.

Dogwood blooms in early to mid-spring, usually before or simultaneous with leaf emergence. The white bracts are 1.5–2 inches long each, giving the full "flower" cluster a diameter of 3–4 inches. Pink forms are cultivated selections; the wild species produces white bracts.

Eastern redbud (Cercis canadensis)

Redbud is a member of the legume family (Fabaceae). Per Missouri Botanical Garden, its flowers are small, pea-shaped (papilionaceous), and emerge directly on branches and older wood — even on the main trunk of mature trees. This characteristic, called cauliflory, is dramatic and diagnostic.

Flowers are typically magenta-pink to rose-purple, emerging in clusters of 4–8 before leaves appear. The white cultivar 'Alba' exists but is uncommon. Per Clemson HGIC, redbud blooms 1–2 weeks before or simultaneous with dogwood in most of its range — zone 4 to 9.

Leaf identification

Dogwood leaves

Per NC State Extension, flowering dogwood leaves are:

• Opposite (paired at each node)
• Oval to elliptical, 3–6 inches long
• Smooth margin (no serration)
• Arcuate (curved) venation: The secondary veins curve upward and follow the leaf margin toward the tip rather than heading straight to the edge. This curved-vein pattern is characteristic of the dogwood genus (Cornus).

A simple test: gently pull apart a dogwood leaf that has started to tear. The threads of the veins stretch like rubber bands and hold the torn pieces together briefly. This "stringy vein" phenomenon is a well-known field trick for dogwood, though it requires a leaf rather than a winter twig.

Summer foliage is dark green; fall color is burgundy to maroon-red — one of the more reliable red fall colors among understory trees.

Redbud leaves

Per Missouri Botanical Garden, redbud leaves are:

• Alternate (one per node)
• Heart-shaped (cordate) with a rounded or slightly indented tip — a very distinctive leaf silhouette
• 3–5 inches in diameter, roughly as wide as long
• Smooth margin, with palmate venation (several veins radiate from the leaf base)

The heart-shaped leaf with palmate venation is diagnostic for Cercis and separates it from dogwood immediately. Fall color is yellow, unremarkable.

Bark and form

Flowering dogwood: Per NC State Extension, young dogwood bark is smooth and gray; mature bark develops blocky, small, grayish-brown plates, sometimes described as resembling alligator skin. Dogwood typically grows as a multi-stemmed small tree or large shrub, 15–30 feet, with a flat-topped or layered horizontal branching habit.

Eastern redbud: Bark is smooth gray to brown-gray on young trees, developing shallow fissures and interlacing ridges with age. Redbud typically grows 20–30 feet, often with multiple stems, and has a more rounded crown than dogwood. Per Clemson HGIC, redbud's branching is more irregular and less distinctly layered than dogwood.

Fruit identification

Dogwood fruit: Clusters of oval, bright red drupes (0.4–0.5 inch) in fall. Per NC State Extension, the red fruits are a critical fall food source for migrating birds, including thrushes and waxwings. They are technically edible but very bitter to humans.

Redbud fruit: Flat, papery pods (legumes) 2–4 inches long, in clusters, turning brown and papery by late summer and persisting through winter. Per Missouri Botanical Garden, the clusters of brown bean pods hanging on bare winter branches are a reliable cold-season ID feature.

Diseases and problems

**Dogwood anthracnose (Discula destructiva):** Per Penn State Extension, dogwood anthracnose is a serious fungal disease of flowering dogwood, particularly in shaded, moist conditions. Symptoms include irregular leaf spots with tan centers and purple borders, blighted shoots, and cankers on branches and the main stem. Planting dogwood in full sun with good air circulation reduces risk.

Redbud issues: Redbud is relatively pest- and disease-free but susceptible to canker diseases (Botryosphaeria canker) in stressed trees. Per Clemson HGIC, redbud is short-lived compared to many trees — 20–25 years is typical, though some specimens live longer in ideal conditions.

Frequently asked questions

Is there a pink dogwood or is that redbud? Both exist. Pink flowering dogwood is a cultivated selection of Cornus florida with pink rather than white bracts — 'Cherokee Princess' is white; 'Cherokee Chief' is dark pink-red. Eastern redbud is naturally magenta-pink. Per NC State Extension, the key separator in spring is flower structure: dogwood bracts are large, notched, and surround a central cluster; redbud flowers are small, pea-shaped, and emerge from bare stems.

Can I grow flowering dogwood in zone 7? Yes. Per NC State Extension, Cornus florida grows in zones 5–9. In zone 7 Long Island, flowering dogwood performs well in light shade or dappled sun — it prefers protection from the hottest afternoon sun, especially in drier years. The kousa dogwood (Cornus kousa, zones 5–8) is a related Asian species with pointed rather than notched bracts and better disease resistance to anthracnose.

Do deer eat dogwood or redbud? Both are browsed by white-tailed deer, though neither is a preferred species. In my zone 7a Long Island yard with moderate-to-high deer pressure, any new planting of either species would need tube protection for the first several years. Per Rutgers NJAES, both flowering dogwood and redbud are rated "occasionally severely damaged" by deer.

What replaced dogwood as a street tree after anthracnose spread? Per Penn State Extension, Cornus kousa (kousa dogwood) and its hybrids with C. florida (the 'Stellar' series) are now preferred in many landscapes because of improved anthracnose resistance. Kousa dogwood flowers 2–4 weeks later than C. florida and has a less graceful form but significantly better disease tolerance.
