Dogwood Facts, Dogwood (Cornus) gives gardens an ornamental four-season tree. Get Dogwood facts and a list of dogwood varieties to plant in your landscape.
The genus, Cornus, contains several varieties of flowering trees that range from trees to shrubs to groundcovers. The shrubs and trees are notable for their refined form, while others may have a spreading habit fit for short or tall groundcovers and attracting wildlife.
In nature, dogwoods usually occur in the forest understory and at the woodland’s edge, where they exhibit an appealing delicacy of form because of the restricted light. They also look lovely grouped in a large lawn or as specimen trees in both large and small sunny landscapes, where they are low-branched, full, and spreading.
There are many varieties of dogwood, allowing you to grow different types of dogwood for flashy pink or white flowers (which are actually four petal-like bracts), for fine fall color, attractive red fruits or white berry clusters, or for the decorative flaky to colorful bark.
Dogwoods will have such diseases as anthracnose, powdery mildew, and canker.
Helpful anthracnose controls: Mulch the root zone to conserve moisture, then clean up dropped leaves fast. Do not overfeed and water by soaker hose instead of overhead sprinklers during dry spells.
