Which Dogwood Belongs in Your Garden? Florida, Kousa, Stellar, and Pagoda Types Compared
Pick the right dogwood for your zone: Florida, Kousa, Stellar, and Pagoda types compared by bloom time, size, and anthracnose resistance.
Dogwood season runs longer than most gardeners realize — and most of that extended bloom belongs to types they’ve never planted. The native Cornus florida opens for roughly two weeks in early spring, then fades. Plant a Kousa dogwood beside it and you get a second wave four to six weeks later. Add a Stellar hybrid and you split the difference. Put a Pagoda dogwood at the back of a shaded border and it carries blooms, blue-black fruit, and dramatic tiered architecture from May through October.
But choice matters for another reason: Cornus florida, the flowering dogwood beloved across the American South, has been fighting a losing battle with Discula destructiva anthracnose since the fungus arrived in the 1970s. In humid climates especially, the wrong cultivar planted in the wrong spot will struggle for years before failing. Understanding which type — and which cultivar within that type — suits your zone is the difference between a dogwood that thrives and one that spends its life in decline.
This guide covers the four types you’re most likely to encounter: Cornus florida, Cornus kousa, the Rutgers Stellar series hybrids (Cornus × rutgersensis), and Cornus alternifolia (Pagoda dogwood). Each has a distinct bloom window, size range, and disease profile. A choosing matrix at the end matches each type to specific zones and garden situations.
Flowering Dogwood (Cornus florida) — The Native Classic
Flowering dogwood is native to the eastern United States, reaching from Maine to northern Florida and west to Kansas. It earns its place in the landscape through sheer seasonal drama: four large, rounded bracts — technically modified leaves, not true petals — surround a cluster of tiny yellow-green flowers in early spring, before a single leaf emerges. White is the most common form, but pink-bracted cultivars like ‘Cherokee Chief’ and ‘Cherokee Brave’ have been in cultivation for decades.
Bloom timing tracks closely with USDA zone. In Zones 7 and 8, expect peak flowering in early April. In Zones 5 and 6, the show peaks in late April to early May. The entire display lasts about two weeks regardless of location, so plant placement matters: a tree tucked behind taller evergreens loses much of its visual impact during that brief window.
Mature size varies by cultivar, but most Cornus florida specimens reach 15 to 25 feet tall with a spread of 15 to 30 feet, forming a classic layered canopy that reads as a small ornamental tree [2]. It grows at a medium pace — expect six to twelve inches per year in good conditions.
The disease problem is real and worth confronting directly. Discula destructiva, the fungus responsible for dogwood anthracnose, arrived in North America in the late 1970s. Cornus florida had no evolutionary exposure to this pathogen — the species developed in a world where D. destructiva simply didn’t exist. The fungus enters during cool, moist spring weather, starting with lower canopy leaves: tan spots appear first, edged with irregular purple margins, then progress upward as infected shoots develop brown elliptical cankers that can girdle branches entirely, according to Clemson University’s disease guide and WVU Extension. In shaded, humid sites the disease can kill a tree in a few seasons.
The practical response is cultivar selection. ‘Appalachian Spring’ shows the highest resistance to Discula anthracnose among C. florida selections and remains the go-to recommendation in high-humidity areas where the species is otherwise appropriate [5]. For powdery mildew — a separate but common problem — ‘Appalachian Joy,’ ‘Appalachian Blush,’ ‘Appalachian Snow,’ and ‘Appalachian Mist’ all perform well. ‘Cherokee Princess’ and ‘Cherokee Brave’ offer resistance to spot anthracnose, which is caused by a different fungus (Elsinoe corni) and is less lethal but disfiguring during wet springs.
Best for: Zones 5–9 in dry-spring climates; woodland garden edges; gardeners who want the classic spring bract display. In zones 6–8 with humid springs, always plant resistant cultivars and avoid shaded, poorly ventilated sites.
Kousa Dogwood (Cornus kousa) — The Disease-Resistant Alternative
Kousa dogwood is native to China, Japan, and Korea — and that origin is precisely why it handles Discula destructiva better than its American cousin. The pathogen and C. kousa co-evolved in Asia, giving the species time to develop genetic defenses that C. florida never acquired [6, 7]. When conditions favor heavy infection pressure, C. kousa typically shows only minor leaf spotting where C. florida would be losing branches.
There’s an important nuance competitors consistently miss: resistance in Kousa is not a species-wide guarantee. Research published in Arboriculture & Urban Forestry found that C. kousa ‘Chinensis’ was “quite susceptible” to dogwood anthracnose in controlled trials, while unnamed C. kousa seedlings showed strong resistance. Cultivar matters. Select named, disease-tested cultivars rather than assuming any Kousa will be immune.
Bloom time is the other major differentiator. Kousa flowers arrive four to six weeks after C. florida — and after the foliage has already opened. The pointed, star-shaped bracts (versus the rounded bracts of florida) emerge from a backdrop of glossy green leaves, creating a quite different visual effect. In Zones 5 and 6, expect peak bloom in mid-May to early June. In Zones 7 and 8, late April to May. The display lasts up to six weeks — three times longer than the florida bloom [3].
Kousa grows slightly larger than florida: 20 to 30 feet tall with a 15 to 30 foot spread. Young trees have a vase-shaped habit that broadens with age. The exfoliating bark — patchy tan and gray-brown — provides genuine winter interest that most small ornamental trees lack. Fall brings edible, raspberry-like fruit measuring one to one and a half inches in diameter; it’s sweet and soft when fully ripe, and attracts birds and squirrels [3].
Cultivar picks: ‘Satomi’ for soft pink bracts (unusual for Kousa and highly sought after); ‘Moonbeam’ for bracts reaching seven inches — among the largest of any dogwood; ‘Lustgarden Weeping’ for a compact eight-foot weeping form that fits smaller gardens or containers; ‘Gold Star’ for yellow-blotched summer foliage if you want year-round color.
Best for: Zones 5–8; humid climates where C. florida struggles; gardeners who want a second bloom wave; those needing an ornamental tree with four-season interest. Not the right choice for Zone 3 or 4, or gardens that need a tree under 15 feet (Lustgarden Weeping excepted).
Stellar Series Hybrids (Cornus × rutgersensis) — The Best of Both
The Stellar series came from one of the more ambitious tree breeding programs of the twentieth century. Dr. Elwin Orton at Rutgers University spent decades crossing Cornus florida and Cornus kousa, aiming for a tree that combined the early bloom and large rounded bracts of the American species with the disease resistance and vigor of the Asian one [8]. The result was six named cultivars released under the Rutgers name, marketed collectively as the Stellar® series (Cornus × rutgersensis).
Every cultivar in the series carries resistance to both dogwood anthracnose and dogwood borer — the latter being an insect pest that targets native florida trees and is absent from the Kousa’s natural enemies list. Bloom timing falls between the parents: mid-spring, after early-season florida trees but before Kousa reaches peak. Zones 5 through 9 — the widest cold-hardiness range of any dogwood group covered here [4].
The six cultivars are meaningfully different in form and should be chosen based on your garden’s space and aesthetic goals — a breakdown confirmed by the Morton Arboretum:
| Cultivar | Form | Mature Size | Flower Color | Best For |
|---|---|---|---|---|
| Aurora | Spreading | 20 ft × 20 ft | White | Wide borders, heavy bloom effect |
| Celestial | Upright | ~20 ft | Creamy white | Narrow spaces, formal rows |
| Constellation | Very erect | 20 ft × 17 ft | Creamy white | Street tree, confined widths |
| Ruth Ellen | Spreading | ~15 ft | Brilliant white | Smaller gardens, earlier bloom |
| Stardust | Low-branching | ~15 ft | White | Ground-level visual impact |
| Stellar Pink | Erect | 23 ft × 18 ft | Pink | Only pink in the series; focal specimen |
Stellar Pink deserves special mention: it’s the only cultivar in the group with pink bracts, making it the choice for gardeners who want the classic pink dogwood look without the disease vulnerability of pink-bracted C. florida selections.
Best for: Zones 5–9; gardeners who want C. florida aesthetics without the disease risk; humid climates; urban or street planting (especially Constellation for narrow profiles).
Pagoda Dogwood (Cornus alternifolia) — The Native for Northern Zones
Pagoda dogwood is the outlier in this group. It’s not grown primarily for large showy bracts — it blooms in late May to June with small, fragrant, creamy-white flowers arranged in flat-topped clusters two to three and a half inches across, appearing after the foliage has opened, according to the NC State Extension Plant Toolbox. The flowers are subtle compared to the spectacle of C. florida or Kousa. What pagoda offers instead is architecture and wildlife value that no other dogwood matches.
The common name describes the growth habit accurately: strongly horizontal branching arranged in distinct tiers, like the levels of a pagoda. In a garden with mostly rounded forms, a mature pagoda dogwood reads as a structural accent through all four seasons — bare tiered branches in winter, flower clusters in late spring, blue-black drupes in summer, reddish-purple fall foliage. Those blue-black berries attract a disproportionate number of bird species: grouse, pheasants, wild turkeys, and various songbirds all target the fruit [1].
The other major reason to grow pagoda dogwood is its cold hardiness. Zones 3 through 7b — it’s the only tree in this comparison that’s fully reliable in Zone 3, where winters regularly reach -40°F. Cornus florida tops out at Zone 5; Kousa and Stellar manage Zone 5 at best. If you garden in the upper Midwest, northern New England, or Canada, pagoda dogwood is the type that actually survives without a winter gamble.
Mature size is wider than tall: 15 to 25 feet high but 20 to 32 feet wide [1]. Give it room. It’s a shade-tolerant understory tree that performs well below oaks and maples, which suits it to woodland garden situations where a full-sun dogwood would struggle.

Best for: Zones 3–7; northern gardens where other dogwoods aren’t cold-hardy; woodland and understory situations; wildlife gardens; gardeners who want architectural structure over bract display.
Which Dogwood Is Right for Your Garden?
Here’s the four-way comparison at a glance:
| Type | Zones | Bloom Time | Size (H × W) | Anthracnose Risk | Best Situation |
|---|---|---|---|---|---|
| Cornus florida | 5–9 | March–May (before leaves) | 15–25 ft × 15–30 ft | High (unless resistant cultivar) | Dry-spring climates; woodland edge |
| Cornus kousa | 5–8 | 4–6 weeks after florida | 20–30 ft × 15–30 ft | Low (cultivar-dependent) | Humid climates; second-wave bloom |
| Stellar Series | 5–9 | Mid-spring (between parents) | 15–23 ft × 15–20 ft | Resistant (all cultivars) | Widest zone range; pink option |
| Cornus alternifolia | 3–7 | Late May–June (after leaves) | 15–25 ft × 20–32 ft | Low (naturally resistant) | Northern zones; wildlife; shade |
Use this decision guide based on your situation:
- Zone 3 or 4: Pagoda dogwood is your only reliable choice from this list. Plant it as an understory tree and let the birds find it.
- Zones 5–6, humid spring (Midwest, Great Lakes, New England): Kousa or Stellar series. Disease pressure from Discula is too consistent for unprotected C. florida.
- Zones 5–7, dry spring climate (mountain West, parts of the Midwest): Cornus florida ‘Appalachian Spring’ works well — disease pressure is lower when springs are dry.
- Zones 7–9, Southeast and Mid-Atlantic: Stellar series gives you the early-spring bloom window of C. florida combined with disease resistance that humidity demands. Or choose a Kousa for late-spring color and four-season interest.
- Small garden or tight space: Kousa ‘Lustgarden Weeping’ (8 ft) or Stellar ‘Stardust’ (low-branching, ~15 ft). Both stay manageable without hard pruning.
- Wildlife priority: Pagoda dogwood for blue-black berry crops, or C. florida for its bright red drupes that persist into winter and attract thrushes, robins, and cedar waxwings.
- Only pink will do: Stellar Pink is the most disease-resistant pink-bracted dogwood available, outperforming pink C. florida selections in humid conditions.

Planting and Care Across All Four Types
Despite their differences in bloom time and cold hardiness, all four dogwood types share a similar set of basic requirements.
Soil: Slightly acidic (pH 5.5–6.5), well-drained, and rich in organic matter. Dogwoods have naturally shallow root systems — they’re adapted to forest edges where they compete with larger trees for surface moisture. This makes them vulnerable to waterlogging and, paradoxically, to drought. Heavy clay that stays wet through spring actively promotes Discula anthracnose in susceptible types [5].
Sun: Full sun to part shade. In Zones 7–9, afternoon shade reduces heat stress and slows soil moisture loss. Kousa handles sun better than florida; Pagoda is the most shade-tolerant of the four.
Watering: The first two growing seasons are critical. Water deeply once a week during dry spells — enough to wet the soil 12 to 18 inches deep. After establishment, all four types are moderately drought-tolerant except in extreme conditions.
Mulch: Apply a three to four inch layer of organic mulch over the root zone, keeping it several inches away from the trunk. Every dogwood I’ve planted has benefited from consistent mulching through its first three summers — it buffers soil temperature, retains moisture, and reduces the competition stress that makes trees more vulnerable to disease during August dry spells.
Pruning: Dogwoods need minimal pruning. Remove dead or crossing branches in late summer or early fall — not in spring, when fresh cuts attract dogwood borer adults that emerge from late April through July [5]. Pruning in late summer also avoids stimulating new growth that won’t harden before winter.
Frequently Asked Questions
Which dogwood is the most disease resistant?
The Stellar series hybrids show consistent resistance to both dogwood anthracnose and dogwood borer across all six cultivars. Among species, Cornus kousa is generally more resistant than C. florida, but individual cultivar selection matters — some Kousa selections like ‘Chinensis’ have shown susceptibility in research trials [7].
How fast do dogwoods grow?
Most dogwoods are moderate growers at six to twelve inches per year. Cornus florida is medium-paced; Cornus kousa grows slowly, particularly in its first few years. Patience pays — a well-sited dogwood improves structurally every decade and typically outlives faster-growing ornamental trees.
Can you grow dogwoods in Zone 9?
Cornus florida and the Stellar series reach into Zone 9 at the warm end of their range. Cornus kousa tops out at Zone 8b. If you’re in Zone 9 with hot, dry summers, prioritize afternoon shade and consistent irrigation. Pagoda dogwood is not suitable for Zone 9.
What’s the difference between Kousa and Stellar Pink?
Both are pink-bracted dogwoods with good disease resistance, but they’re different plants. Kousa ‘Satomi’ produces soft pink bracts on a 15 to 20 foot Asian species that blooms four to six weeks after C. florida. Stellar Pink is a C. florida × C. kousa hybrid that blooms in mid-spring (between the parents) on a more upright, 23-foot tree. Stellar Pink tends to be more widely available and offers reliable anthracnose and borer resistance.
Do dogwoods attract pollinators?
Yes, though the mechanism differs by species. The showy “petals” on C. florida and Kousa are actually bracts — modified leaves that attract insect pollinators to the small central flowers. Pagoda dogwood, with its open flat-topped flower clusters, is particularly accessible to small native bees and flies. All four types produce fruit that supports wildlife from late summer through fall.
