There are many species of dogwood, which can be shrubs, trees, or groundcovers. These five species are the tree forms most used in gardens.

Flowering Dogwood

Cornus florida

This is the tree many gardeners think of first when they think of dogwood trees. It is hardy in zones 5 though 9, with white, pink, or red flowers and red fall color. Flowering dogwood is admired for its graceful habit of growth, which gives a layered aspect to the small trees. Many varieties are available for planting. See Cornus Florida for more information.

Flowering dogwood needs rich, fertile, acidic soil. Evenly moist to wet conditions are important for healthy growth; trees stressed by drought are susceptible to a variety of problems. Cornus florida grows in sun or light shade, with heavier flowering in full sun but greater growth in shade.

Japanese Flowering Dogwood

Cornus kousa

This beautiful small tree is native to Asia and is valued by gardeners for its beautiful flower and richly-colored fall foliage. Young trees have a vase-like shape, but older trees have a beautiful layered look.
