Cornus walteri: Walter Dogwood1

Edward F. Gilman and Dennis G. Watson2

Introduction

Walter Dogwood is a medium-sized deciduous tree reaching 30 to 40 feet in height and width. The two to five-inch-long leaves are dark green and are joined in June by the small white flowers arranged in two to three-inch diameter cymes. The blossoms are followed by the production of small black fruits which are popular with birds and other wildlife. Walter Dogwood is probably best known for the alligator-like bark on older specimens, even more so than Flowering Dogwood. Young specimens have an upright branching habit giving way to an open spreading habit. The branches probably droop less than most other Dogwoods, making it a possible candidate for street tree use although they have not been tested for this in the United States. Most certainly a good patio tree providing shade quickly.

Use and Management

Grown in the full sun it develops a dense canopy but is more open and perhaps more attractive in partial shade. The plant is now rare in the industry but deserves to be tried. It is highly drought tolerant and grows well in clay soil.

Propagation is by cuttings or seed.

Pests

No pests are of major concern at this time.

Diseases

Possibly leaf spot, twig blight, or canker. See diseases section of Flowering Dogwood.
