About Dogwood Trees
Dogwoods belong to the genus Cornus and are notable for their vibrant spring blooms, striking bark, and wide adaptability. With more than sixty species and countless cultivars, dogwoods range from majestic trees to low-growing groundcovers, making them ideal for diverse landscaping needs.

- Showy spring flowers: Large, four-petaled blooms in white, pink, or yellow tones.
- Distinctive bark: Attractive patterns and colors, adding winter interest.
- Colorful fruit: Drupes in shades from white to blue and red, providing bird food.
- Seasonal foliage: Leaves turning shades of red, orange, or purple in autumn.
Main Types of Dogwood
Dogwoods can be broadly grouped based on their growth form:
- Tree-form dogwoods: Such as flowering dogwood (Cornus florida) and Kousa dogwood (Cornus kousa).
- Shrub-form dogwoods: Red osier (Cornus sericea), silky (Cornus amomum), and more.
- Groundcover dogwoods: Creeping dogwood (Cornus canadensis).

Dogwood in Landscape Design
Dogwood trees and shrubs are versatile landscape plants. Their broad, flat crowns or horizontal layers create focal points, while colorful bark and blooms provide seasonal highlights. Here are some ways to incorporate dogwoods into garden designs:
- Specimen planting: Showcase a single dogwood for dramatic spring blooms and fall foliage.
- Mixed borders: Combine with azaleas, ferns, or hostas for layered texture.
- Woodland gardens: Underplant with shade-loving perennials to mimic natural forest growth.
- Hedges and screens: Use shrub dogwoods for living fences or winter color.
- Rain gardens: Red osier and silky dogwoods thrive in wetter soils—ideal for rainwater absorption.
Planting Dogwood Trees and Shrubs
Choosing the Right Site
- Sunlight: Dogwoods thrive in full sun to partial shade. For optimal growth, select a location with at least 4–6 hours of sunlight, but offer protection from harsh afternoon rays.
- Soil: Well-drained, moist, slightly acidic soil is best. Amend with compost if drainage is poor.
- Space: Ensure enough room for mature spread, as many dogwoods grow wider than tall.
How to Plant
- Dig a hole twice as wide and as deep as the root ball.
- Loosen soil at the base and sides of the hole.
- Gently set the dogwood at the same depth it was growing in the nursery container.
- Backfill with native soil, mixing in organic matter if needed.
- Water thoroughly to settle the soil, and apply 2–3 inches of mulch, keeping mulch away from the trunk.
Dogwood Tree Care Tips
- Watering: Keep soil consistently moist, especially for the first few years. Water weekly during dry spells.
- Mulching: Mulch helps retain moisture and regulate soil temperature. Refresh mulch annually.
- Fertilizing: Dogwoods generally do not require heavy fertilization. Apply a balanced slow-release fertilizer in early spring if growth is weak.
- Pruning: Prune after flowering to remove dead or crossing branches and shape the plant. Avoid heavy pruning, as dogwoods flower on old wood.
- Pest and Disease Management: Watch for powdery mildew, dogwood anthracnose, and borer insects. Provide good air circulation and avoid wetting foliage to prevent disease.
Dogwood Varieties: Features and Benefits
- Milky Way Kousa Dogwood: Profuse white flowers and edible fruits; strong structure and disease resistance.
- Pagoda Dogwood: Striking horizontal branches, shade tolerance, subtle creamy-white flower clusters.
- Prairie Fire Red Twig Dogwood: Brilliant red-orange winter stems; low-maintenance and drought-tolerant once established.
- Stellar Pink® Dogwood: Soft pink flowers, excellent disease resistance, compact size.
- Variegated Red Twig Dogwood: Red stems with variegated green and creamy white leaves for multi-season interest.
- White Kousa Dogwood: Showy white late spring blooms, attractive exfoliating bark, and edible berry-like fruit.
Dogwoods for Wildlife and Ecology
Dogwoods provide essential food and habitat for local wildlife. Their fruit is enjoyed by birds, including robins, cedar waxwings, and cardinals. Pollinators benefit from the nectar-rich flowers, making dogwoods valuable additions to native and pollinator-friendly gardens. Species like red osier and silky dogwood also stabilize soil and are excellent for naturalizing wetland edges.
Seasonal Interest: Year-Round Beauty
- Spring: Showy bracted flowers create stunning displays.
- Summer: Lush foliage and developing fruit add garden texture.
- Fall: Vibrant leaf colors—red, orange, and purple—provide autumn drama.
- Winter: Colorful stems (red or yellow) and textured bark offer off-season interest.
