- Description
-
Flowering Dogwood is a deciduous tree that may grow 15 to 25 feet tall. The leaves are alternate, acutely veined, with a smooth to wavy margin. The bark is smooth when young. As the tree ages, the bark becomes very scaly to finely blocky. A very small and inconspicuous, tight cluster of green flowers surrounded by 4 very showy, large, white (occasionally pink) bracts mature in early spring. The small tree produces a cluster of red drupes that mature in the fall.
The Flowering dogwood is easily grown in average, medium moisture, well-drained soils in full sun to part shade. It prefers moist, organically rich, acidic soils in part shade. It will benefit from a 2-4” mulch which will help keep roots cool and moist in summer. It can withstand hot temperatures as long as the roots remain moist and well-mulched.
Fire Risk: This plant has a low flammability rating.
Insects, Diseases, or Other Plant Problems: Calico scale, dogwood borer, dogwood sawfly, Japanese maple scale, leafhoppers, oyster shell scale. Dogwood anthracnose is not all that common, only occurs at 1800 feet or higher elevation. Spot anthracnose is more common. Trees are also susceptible to powdery mildew, leaf spot, canker, root rot and leaf, and twig blight crown canker, bacterial leaf scorch, powdery mildew, septoria leaf spot. The foliage is browsed by white-tailed deer and these trees do not withstand pollution.
Quick ID Hints:
- Bark is broken into small squares, rectangles
- Small deciduous tree that flowers before leaves
- Fruit is cluster of ovoid drupes, green to red
- Cross-shaped flower of 4 large white, notched bracts
- Lateral veins ecenly spaced
Small, deciduous tree or wide spreading shrub, to 32'.
Blooms in spring before leaves; Fruit ripens from green to red in fall, persists to winter (unless birds eat them); good fall color (red to reddish purple); naked tree has tiered look.
Tolerates full sun to part shade, prefers acid, well-drained, cool, moist soil enriched with organic matter; intolerant high heat loads, drought, extreme cold; insect/disease problems.
