Short answer: plant a kousa dogwood (Cornus kousa) if you want a tough, disease-resistant tree that handles more sun and blooms in late spring; plant a native flowering dogwood (Cornus florida) if you want the classic April display, better wildlife value and you can give it partial shade and good air flow. Both reach a similar size, 15 to 30 feet, and both earn their keep with four seasons of interest. The real differences are bloom timing, how each handles anthracnose and powdery mildew, how much sun they tolerate, and what their fruit is good for. Below is the side-by-side comparison, then each decision factor in detail, and finally clear picks for common yard situations, including where the Rutgers hybrids fit and which varieties give you a pink dogwood.

Key Takeaways
- Flowering dogwood blooms in April before its leaves appear; kousa blooms 3 to 4 weeks later, in May to June, after leafing out.
- Kousa is highly resistant to dogwood anthracnose and more tolerant of sun and drought; flowering dogwood is native and better for birds and pollinators.
- Both grow roughly 15 to 30 feet tall; flowering dogwood is hardy in zones 5 to 9, kousa in zones 5 to 8.
- Kousa fruit is a large, raspberry-like edible berry; flowering dogwood produces small, glossy red berries that birds eat quickly.
- Rutgers Stellar hybrids (kousa x florida) bloom between the two and combine much of kousa’s disease resistance with a florida-like look.

Bloom Time and Flower Display
What looks like a dogwood flower is actually four petal-like bracts surrounding a small button of true flowers. On a flowering dogwood, the bracts open in early to mid April in the mid-Atlantic and Ohio Valley (late March in the Deep South, early May in New England), on bare branches. That is the effect people picture: a tree floating in white or pink against a still-brown woodland. The bracts are rounded with a small notch at each tip.
Kousa waits until its leaves are out, typically mid-May to June. The bracts are pointed and held upright along the tops of the branches, so the tree looks frosted from above, especially when viewed from a deck or upstairs window. Because the bracts are tougher, they often last 4 to 6 weeks and age from creamy white to a pink blush. If you already have a garden full of April bloomers (redbud, cherry, forsythia), kousa extends the flowering season into early summer. If you want a woodland-edge tree that defines spring, florida is hard to beat. Our redbud growing guide covers another native that pairs well with florida’s bloom window.
Getting a pink dogwood
Pink is easiest to get in Cornus florida: ‘Rubra’ (pink), ‘Cherokee Chief’ (deep rosy red), and ‘Cherokee Brave’ (red-pink with a white center and better mildew resistance) are long-standing nursery selections. Pink kousas include ‘Satomi’ and Rutgers’ ‘Scarlet Fire’, which has some of the deepest pink bracts available in a kousa. Pink color in both species is stronger in cooler springs and with a bit of afternoon shade; hot weather can fade it.
Disease Resistance
This is the factor that most often decides the question. Dogwood anthracnose, caused by the fungus Discula destructiva, was first noticed in the US in the late 1970s and has since killed large numbers of wild flowering dogwoods, especially in cool, moist, shaded sites in the Appalachians and Northeast. Symptoms include tan leaf spots with purple margins, dead twigs, and cankers that eventually girdle limbs. Cornus kousa is highly resistant to it.
Powdery mildew is the second common problem on florida, coating leaves in white film in humid summers and weakening trees over time. Again, kousa is largely resistant. Flowering dogwood also attracts the dogwood borer, which enters through bark wounds, often from lawn mowers and string trimmers. Kousa is less troubled by borers, though no tree is immune.
You can reduce florida’s risk significantly with the right variety and site. ‘Appalachian Spring’ was selected from a surviving tree in an anthracnose-ravaged forest and shows strong resistance. ‘Cherokee Brave’ and the Jean’s Appalachian series offer improved powdery mildew resistance. Plant in a spot with morning sun and good air movement, mulch to protect roots and bark, and keep lawn equipment well away from the trunk.
Sun, Soil and Climate Tolerance
Flowering dogwood evolved as an understory tree beneath oaks and hickories. It does best in partial shade, ideally morning sun with protection from hot afternoon sun, in moist, acidic, well-drained soil rich in organic matter. In full sun it can grow well if irrigated and deeply mulched, but leaf scorch and stress-related borer problems are more likely. It is shallow-rooted and dislikes compacted or soggy soil.
Kousa handles full sun better, tolerates a wider range of soils, and copes with short dry spells once established, though it still prefers acidic, well-drained ground and benefits from deep watering during summer droughts. Where it struggles is extreme heat: kousa is generally rated to zone 8, and in hot, humid parts of zone 8 and in zone 9 it can decline. Flowering dogwood extends into zone 9 across much of the Southeast, making it the better fit for Atlanta or Birmingham gardens with shade. In the colder edge of zone 5, both species can lose flower buds in hard winters, so choose a sheltered site.
Size, Shape and Growth Rate
Both trees mature at roughly 15 to 30 feet tall with a similar spread, and both grow at a slow to moderate rate of about 1 foot per year once established. Flowering dogwood has a layered, horizontal branching pattern that looks wonderful in winter. Kousa starts out more upright and vase-shaped, then broadens with age into a rounded crown. Kousa’s exfoliating bark becomes a feature on older trunks, with patches of tan, gray and cinnamon, and many gardeners limb up lower branches to show it off.
Either tree fits a typical suburban front yard. Plant at least 10 to 15 feet from the house and 8 to 10 feet from driveways or walks so the canopy can develop fully. Our guide on how to plant a tree covers hole width and planting depth, which matter a lot for shallow-rooted dogwoods; setting the root flare too deep is a common reason young dogwoods fail.
Fruit and Wildlife Value
Flowering dogwood produces clusters of small, glossy red fruit in early fall. They are high in fat, which makes them an important fuel source for migrating songbirds such as thrushes, catbirds and vireos, and they usually vanish within weeks. As a native tree, florida also hosts caterpillars of several native moths and butterflies, including the spring azure. If supporting wildlife is a goal, florida is the stronger choice.
Kousa fruit is a 1-inch, pinkish-red, bumpy ball that hangs from a long stem in late summer. It is edible: the skin is gritty, but the orange pulp tastes like a mild mix of mango and persimmon. Squirrels and some birds eat it too. The downside is mess; dropped fruit can be slippery on patios and walks, so site kousa away from hard surfaces if that bothers you.
Seasonal Interest Through the Year
| Season | Kousa dogwood | Flowering dogwood |
|---|---|---|
| Spring | Fresh green leaves; buds forming | Main bloom on bare branches |
| Early summer | Main bloom, lasting weeks | Full green canopy |
| Late summer | Large red fruit | Berries ripening |
| Fall | Red to purple leaves | Red to burgundy leaves, red berries |
| Winter | Exfoliating mottled bark | Layered branches, button-like flower buds |
The Hybrid Option: Rutgers Stellar Dogwoods
In the late 20th century, Dr. Elwin Orton at Rutgers University crossed kousa and florida to combine the best of both. The resulting Stellar series, now classified as Cornus x rutgersensis, includes ‘Aurora’, ‘Celestial’, ‘Constellation’, ‘Stardust’ and ‘Stellar Pink’. They bloom in the gap between the two parents, typically late April to May, with large, overlapping bracts. They carry much of kousa’s resistance to anthracnose and dogwood borer, and many have good mildew resistance. Most produce little or no fruit, which is a plus for patios and a minus for wildlife.
The ‘Venus’ dogwood, a cross of kousa with the western Pacific dogwood, is another option with exceptionally large bracts, often 6 inches or more across the flower head, and strong disease resistance. It is hardy to about zone 5.
Care Differences in Practice
- Watering: Both need about 1 inch of water per week during their first two summers. Florida stays more sensitive to drought for life; plan on deep watering during dry spells.
- Mulch: A 2 to 3 inch layer over the root zone, kept a few inches off the trunk, keeps roots cool and protects bark from mowers. See our guide to mulching around trees.
- Pruning: Prune lightly right after flowering, removing dead, crossing or diseased wood. Both form next year’s flower buds in summer, so late pruning removes blooms.
- Fertilizer: Rarely needed in decent soil. Excess nitrogen pushes leaves at the expense of flowers.
- Sanitation: For florida, rake and remove spotted leaves in fall to reduce anthracnose spores.

Which Should You Choose?
- If your site gets 6+ hours of direct sun, choose kousa. It handles sun and moderate dryness far better.
- If you live in a cool, humid area where wild dogwoods have died from anthracnose, choose kousa or a Stellar hybrid.
- If you want the classic April bloom on bare branches and have part shade, choose flowering dogwood, ideally a resistant variety like ‘Appalachian Spring’.
- If you are planting for birds and native insects, choose flowering dogwood.
- If you garden in zone 9 or hot zone 8 in the Southeast, choose flowering dogwood in a shaded site; kousa often struggles in that heat.
- If the tree will sit next to a patio or walkway, choose a Stellar hybrid to avoid fruit drop.
- If you want a long bloom season, plant one of each: florida for April, kousa for late May and June.
Frequently Asked Questions
How can I tell a kousa dogwood from a flowering dogwood?
Look at the bracts and timing. Flowering dogwood blooms in April on bare branches with rounded, notched bracts. Kousa blooms in May or June after leafing out, with pointed bracts. In winter, kousa has peeling, mottled bark while florida has blocky, alligator-like bark.
Is kousa dogwood invasive?
Kousa is not generally listed as invasive in the US, but it can self-seed in some regions, particularly the mid-Atlantic. Check your state’s invasive plant list, and pick up fallen fruit if you notice seedlings appearing.
Can you eat kousa dogwood fruit?
Yes. The ripe fruit is soft and orange inside with a sweet, mild flavor. Scoop out the pulp and discard the gritty skin and seeds. Flowering dogwood berries are not considered edible for people.
How long does it take a dogwood to bloom after planting?
Nursery trees 4 to 6 feet tall usually bloom within one to three years. Trees grown from seed can take 6 to 10 years, which is why buying grafted or nursery-grown named varieties is the norm.
Why is my flowering dogwood not blooming?
Common causes are too much shade, pruning in late summer or fall, a late frost damaging buds, drought stress the previous summer, or excess lawn fertilizer. Young trees may also simply need another year or two to mature.
