Overview
Flowering Dogwood (Cornus florida) is native to eastern North America, while Kousa Dogwood (Cornus kousa) is native to East Asia. Both are prized for their showy spring displays, which are actually colorful bracts surrounding the true flowers.
Care Guide
Light
Partial shade to full sun. In hotter climates, some afternoon shade is beneficial.
Water
Keep the soil evenly moist, especially while establishing. Mulch helps retain moisture.
Soil
Prefers rich, well-draining, slightly acidic soil with plenty of organic matter.
Climate
Cornus florida is more heat-sensitive; Kousa dogwood is often more adaptable in warmer regions.
Mulch
Apply a layer of organic mulch around the base to keep roots cool and moist. Keep mulch away from the trunk.
Pruning
Minimal pruning is needed. Remove dead or crossing branches in late winter if necessary.
Propagation
Can be grown from seed (slow) or by softwood cuttings. Named cultivars are usually grafted or budded.
Common Problems
- Dogwood anthracnose – A fungal disease that can be serious in Cornus florida; choose resistant cultivars or Kousa dogwood where it is a problem.
- Powdery mildew – Can affect foliage in humid conditions.
- Borers – Stressed trees are more susceptible; keep plants healthy with proper watering and mulch.
Interesting Facts
- The showy “petals” are actually bracts; the true flowers are the small cluster in the center.
- Dogwoods provide food and habitat for many birds and pollinators.
- Autumn foliage can be a beautiful red or purple.
- Kousa dogwood produces edible (though not particularly tasty) fruit that looks like raspberries.
