Best dogwood cultivars (Cornus)
The genus *Cornus* contains 30--50 species (taxonomic boundaries are disputed) ranging from small shrubs to large trees, mostly from North America and Asia. For ornamental purposes, the relevant species fall into three groups: flowering dogwoods (*Cornus florida*, native; *C. kousa*, Japanese; and.

The genus Cornus contains 30—50 species (taxonomic boundaries are disputed) ranging from small shrubs to large trees, mostly from North America and Asia. For ornamental purposes, the relevant species fall into three groups: flowering dogwoods (Cornus florida, native; C. kousa, Japanese; and their hybrids), shrubby dogwoods grown for stem color (C. sericea, C. stolonifera, C. alba), and cornelian cherry (C. mas).
Per NC State Extension, Cornus florida is the most widely planted ornamental tree native to the eastern US, but it has become highly susceptible to dogwood anthracnose (Discula destructiva) throughout its native range, leading to large-scale die-offs since the 1970s and a shift toward disease-resistant alternatives.
Flowering dogwood (Cornus florida)
Cornus florida is native from Maine to Florida and west to Kansas, hardy in zones 5—9, and produces 4-inch white (or pink to red in cultivars) "flowers" that are actually bracts surrounding a small true flower cluster, per Missouri Botanical Garden. It blooms April—May and reaches 15—25 ft.
Disease note: Per Cornell Cooperative Extension, dogwood anthracnose caused by Discula destructiva has killed millions of wild and cultivated C. florida throughout the East since the 1970s. The fungus is favored by cool, wet springs. In high-humidity, shaded landscapes, mortality can be severe.
Best cultivars (where growing conditions permit):
- 'Cherokee Chief' — deep rose-red bracts; 20 ft; per Clemson HGIC, one of the most vivid red-bracted cultivars; zones 5—8
- 'Cloud 9' — exceptionally heavy white flowering; wide horizontal branching; 15 ft; per Missouri Botanical Garden, one of the best whites
- 'Cherokee Princess' — white; round bracts with slight overlap; 20 ft; per NC State Extension, good disease resistance relative to other C. florida cultivars
- 'Appalachian Spring' — white; per Penn State Extension, selected for anthracnose resistance among C. florida cultivars; zones 5—8; 15—20 ft
- 'Pendula' — weeping form; 10—15 ft; per Missouri Botanical Garden, a specimen accent for sites with adequate dryness and sun
- 'Cherokee Sunset' — pink bracts plus variegated yellow-edged foliage; 15 ft; dual ornamental interest; zones 5—9
Kousa dogwood (Cornus kousa)
Native to Japan, Korea, and China, C. kousa blooms 2—4 weeks after C. florida, producing star-shaped white to pink bracts pointing outward (rather than the notched round bracts of C. florida). Per Missouri Botanical Garden, it is essentially immune to Discula anthracnose, making it the safer choice for humid climates. Hardy zones 5—8; mature size 15—30 ft.
The fruit is a red, strawberry-like aggregate — edible, mildly sweet, though not commercially significant.
Best cultivars:
- 'Milky Way' — very heavy flowering; 15—20 ft; per Missouri Botanical Garden, the most prolific white kousa in cultivation
- 'Wolf Eyes' — white-variegated foliage (white margins); smaller (8—10 ft); per NC State Extension, excellent for small spaces; zones 5—8
- 'Satomi' — deep pink-red bracts; 15—20 ft; per Penn State Extension, the best pink kousa; RHS Award of Garden Merit
- 'Elizabeth Lustgarten' — weeping habit; 6—10 ft; per Missouri Botanical Garden, the standard weeping kousa
- 'Gold Star' — gold-blotched foliage; 15 ft; zones 5—8
Rutgers hybrids (Cornus × rutgersensis)
Developed at Rutgers University by Dr. Elwin Orton by crossing C. florida × C. kousa, these hybrids inherit the large showy bracts of C. florida and the anthracnose resistance of C. kousa. Per Rutgers NJAES, they bloom between the two parents (May—June) and are hardy in zones 5—8.
The six Rutgers hybrids:
- 'Aurora' — large white overlapping bracts; 25 ft; per NJAES, among the most profusely flowering of the group
- 'Constellation' — white; slightly smaller bracts but very heavy flowering; 25 ft
- 'Celestial' — white; per Rutgers NJAES, excellent fall color; 25 ft
- 'Stellar Pink' — pink bracts; 25 ft; per NJAES, the best pink in the Rutgers series; RHS Award of Garden Merit
- 'Ruth Ellen' — white; spreading, slightly lower habit; 15—20 ft; earlier bloom in the series
- 'Galaxy' — white with wide, overlapping bracts; 30 ft; per NJAES, the tallest and most vigorous of the group
Shrub dogwoods (stem color, native)
These species are grown for winter stem color, not flowers. Per University of Minnesota Extension, they are among the most cold-hardy ornamental shrubs (zones 2—7) and are excellent for wet soils, streambanks, and massed plantings.
Cornus sericea (Red-osier dogwood)
Native from Newfoundland to Virginia and throughout the West; zones 2—7. Stems are bright red, most vivid in winter when leafless. Per UMN Extension, the species grows 7—9 ft and spreads by stolons to form colonies.
Cultivars:
- 'Cardinal' — bright scarlet stems; per UMN Extension, one of the most vivid red selections
- 'Kelseyi' — dwarf (2—3 ft); per Missouri Botanical Garden, the standard compact red-osier for small spaces and edging
- 'Isanti' — 5—6 ft; dense, slightly more compact than the species; developed for Upper Midwest landscapes
Cornus alba (Tatarian dogwood)
From Siberia and Manchuria; bright red stems similar to C. sericea but slightly larger; zones 2—8. Per Missouri Botanical Garden:
Cultivar: 'Elegantissima' — white-variegated foliage plus red stems; 8—10 ft; per Missouri Botanical Garden, provides both foliage and winter stem interest in one shrub; zones 3—7.
Cornus racemosa (Gray dogwood)
Native to eastern North America; zones 3—8; white stems (not red) and white berry clusters in fall that attract birds. Per Illinois Extension, one of the best native shrubs for bird habitat. Usually sold as straight species; no widely grown named cultivars.
Cornelian cherry (Cornus mas)
Per Missouri Botanical Garden, C. mas is a large shrub or small tree (15—25 ft), native to Europe and Asia, hardy in zones 4—8, and among the earliest-blooming woody plants in the garden — tiny yellow flowers on bare stems in February—March. The cherry-like red fruit is edible (sour, used for preserves in Eastern Europe). Relatively deer-resistant.
Cultivar: 'Golden Glory' — per Missouri Botanical Garden, the heaviest-fruiting selection; also slightly more compact (15—20 ft); the standard ornamental selection.
Common problems
| Symptom | Cause | Fix |
|---|---|---|
| Dark spots on leaves, tan centers; branch dieback | Dogwood anthracnose (Discula destructiva) | Switch to C. kousa or Rutgers hybrid; improve air circulation; avoid overhead irrigation |
| Powdery white coating on foliage | Powdery mildew | More cosmetic than anthracnose; improve air circulation; more common on shaded plants |
| Borer exit holes in trunk | Dogwood borer (Synanthedon scitula) | Prevent with permethrin bark spray per Cornell CALS; borers enter through wounds — avoid trunk injury |
| Pale green stems losing winter color on shrub types | Normal as stems age | Remove 2-year-old and older stems annually; new growth is the brightest |
Frequently asked questions
Which dogwood has the best disease resistance? Cornus kousa is essentially immune to dogwood anthracnose, per NC State Extension. Among flowering dogwoods, the Rutgers hybrids ('Aurora', 'Stellar Pink', 'Constellation', etc.) offer the best anthracnose resistance while retaining the large showy bracts of C. florida.
Do shrub dogwoods need pruning? Per UMN Extension, the brightest stem color on C. sericea and C. alba is on first-year stems. Remove one-third of the oldest (darkest) stems each late winter to keep the plant producing new, vivid stems.
**Can I grow Cornus florida in zone 9?** C. florida is rated to zone 9 in some sources but performs poorly in the deep South due to insufficient winter chilling and susceptibility to heat stress, per Clemson HGIC. For zone 8—9, C. kousa or a Rutgers hybrid is a better choice.
What is the best dogwood for wet soil? Cornus sericea (red-osier dogwood) is the most tolerant of wet and even periodically flooded soils, per UMN Extension. It is suitable for rain gardens, streambanks, and low spots.
