Introduction
This graceful and informal shrub may grow 2 to 6 feet in height and may spread 6 to 10 feet. Its arching stoloniferous stems support large, glossy, evergreen leaves. These dark green leaves turn to a purple-green color in the winter. The April flowers of coastal leucothoe are very small and occur in bell-shaped racemes. These flowers are white or pinkish-white and are borne in the leaf axils. The fruits of this shrub are inconspicuous capsules.

Use and Management
Coastal leucothoe is outstanding in masses and is a good choice for enclosed city gardens. It is commonly used in the landscape as a specimen, ground cover, and border plant. This shrub is also impressive when naturalized along wooded stream banks.
Coastal leucothoe should be grown in a partially or densely shaded site; it grows best in areas that receive morning sunlight. The soil in its natural, bald cypress dome habitat has a high organic matter and silt content and is acidic. This makes dog hobble a good choice for shaded, wet sites. This plant can be rejuvenated into vigorous growth in the center of the plant if the 2- and 3-year-old canes are removed after bloom.
Coastal leucothoe is propagated by seeds and cuttings.
Pests and Diseases
Leaf spots may cause coastal leucothoe to look undesirable; at least 8 species of fungi infect Leucothoe spp. When this plant is grown in conditions that are not ideal, leaf spot will produce ugly lesions that often enlarge and consume the entire leaf. Root rot problems may also occur in wet soil.
