Flowering Dogwood

Growing Conditions

Growing Zones

Thrives in USDA Zones 5 - 9

Companion Planting

When to Plant

• Transplant

  Plant balled-and-burlapped or container nursery stock in early spring before bud break, or in early fall at least 6 weeks before first frost

• Harvest

  Ornamental; harvest cut branches with buds in late winter for forcing indoors, or gather ripe red berries in autumn for wildlife or propagation

Organic Growing Tips

• Apply a 3–4 inch layer of shredded leaf or wood chip mulch annually over the root zone to retain moisture, moderate soil temperature, and slowly build the humus layer dogwoods naturally favor

• Top-dress with finished compost each spring rather than fertilizing; excess nitrogen encourages soft growth susceptible to powdery mildew and borers

• Brew a dilute compost tea and drench the root zone in early spring to stimulate beneficial soil biology and support the mycorrhizal associations dogwoods depend on for nutrient uptake

• Avoid any soil disturbance or cultivation beneath the canopy; shallow roots are easily damaged and the wound sites invite dogwood borer

• Plant native groundcovers such as wild ginger or native ferns beneath the canopy instead of turf to eliminate the need for string trimming near the trunk, a leading injury vector for borers

• If powdery mildew is recurrent, improve air circulation through light canopy thinning and select resistant cultivars like 'Appalachian Spring' for future plantings

Common Pests

• Dogwood Borer
• Scale Insects
• Dogwood Club-gall Midge
• Leaf Miners
• Aphids
• Powdery Mildew
• Dogwood Anthracnose
• Spot Anthracnose
• Crown Canker

Natural History

Cornus florida is native to the deciduous forests of eastern North America, ranging from southern Maine to northern Florida and west to the Great Plains margin. It evolved as a woodland understory tree, flourishing beneath oaks and hickories where dappled light and rich leaf-litter soils prevailed. The genus name Cornus derives from the Latin for horn, referencing the hardness of the wood, which was historically prized for tool handles, spindles, and weaving shuttles. Cherokee, Iroquois, and other eastern Indigenous peoples documented extensive uses of bark and root. For growers, understanding its understory origin explains why it resents compacted soils, full midday sun in hot climates, and the root competition of lawn grasses.

Traditional Use

Eastern North American Indigenous peoples, including Cherokee and Iroquois communities, documented uses of Cornus florida bark and root in historical ethnobotanical records. The bark was particularly noted in 19th-century American materia medica as a substitute for Cinchona bark during quinine shortages. Historical records reflect a range of ceremonial, practical, and botanical applications across multiple cultures.

• Cherokee (eastern North America, pre-contact through 19th century) - root bark

  Cherokee ethnobotanical records documented the root bark of Cornus florida as an ingredient in preparations associated with fevers; the tree also held significance in ceremonial contexts documented by early ethnographers

• American eclectic medicine (United States, 19th century) - bark

  During the American Civil War and earlier periods of Cinchona shortage, physicians of the eclectic school documented Cornus florida bark as a tonic bitter and fever-tree substitute, described in publications including the King's American Dispensatory

• Iroquois (northeastern North America) - twigs

  Iroquois records documented the use of frayed dogwood twigs as a tooth-cleaning implement and noted bark preparations associated with skin conditions in several historical ethnobotanical surveys

The berries of Cornus florida are considered mildly toxic to humans and may cause vomiting if eaten in quantity, though they are consumed safely by birds; the bark contains tannins and cornine alkaloid that may cause irritation in sensitive individuals

Morphology (Plant Structure & Identification)

• Root System

  Shallow, wide-spreading fibrous roots that extend well beyond the drip line; highly sensitive to soil compaction, grade changes, and drought, making the area beneath the canopy a no-disturb zone for growers

• Stem

  A single-trunked small tree with a layered, horizontal branching habit reaching 15–30 feet; the attractive exfoliating bark on mature trunks provides winter interest, and crossing or rubbing branches should be removed in late winter to maintain structure

• Leaves

  Opposite, ovate leaves with strongly arcuate veins that run parallel to the leaf margin - quick identification feature; leaves turn scarlet to burgundy in fall, and premature yellowing or browning in summer signals drought stress or root damage

• Flowers

  What appear to be four white or pink petals are actually showy bracts surrounding a tight cluster of inconspicuous true flowers in the center; bracts attract early pollinators including native bees and butterflies, and pollen production is important for beneficial insects emerging in early spring

• Fruit

  Clusters of glossy, ovoid red drupes ripen in early autumn and are eagerly consumed by migratory thrushes, waxwings, and other songbirds; seeds within the drupes require double dormancy stratification and are not viable for casual direct sowing

Known Varieties

Common cultivars worth knowing

• Appalachian Spring

  A University of Tennessee introduction with notably strong resistance to dogwood anthracnose, the fungal disease that has decimated wild populations; white bracts and good fall color

  Best for: Humid regions where anthracnose is a persistent problem

• Cherokee Princess

  One of the most widely planted white-bracted cultivars, valued for large, overlapping bracts and reliable heavy bloom even on young trees

  Best for: General ornamental use and landscape planting

• Cherokee Chief

  A deep rose-red to ruby bract cultivar with reddish new foliage; one of the most reliably colorful of the pink-flowered selections

  Best for: Color contrast plantings and focal specimen trees

• Stellar Pink

  A Cornus florida × Cornus kousa hybrid with improved anthracnose resistance, pink bracts, and better heat and drought tolerance than straight Cornus florida

  Best for: Zones 7–9 where heat stress and anthracnose pressure are both high

• Rainbow

  A variegated-leaf cultivar with creamy white and green foliage that turns rose-red in fall; slower growing than the species and best in partial shade to prevent leaf scorch

  Best for: Collectors and gardeners seeking four-season foliage interest
