David's Viburnum

David's Viburnum is a compact, slow-growing evergreen shrub forming dense, low mounds 3 to 5 feet tall and broad. You identify it by the thick, leathery, dark blue-green, narrowly oval leaves, each 5 to 15 centimeters long with conspicuously three prominent veins running lengthwise. In spring, small white flowers open from pink buds in showy rounded clusters 5 to 8 centimeters across, though flowers are less showy than the foliage. The defining ornamental feature is the small, 6-millimeter bright blue oval fruit held on red pedicels that ripen from green through pink and red stages, creating extended seasonal interest; however, you need both male and female plants for fruit production. Foliage takes on burgundy tones in cold months, and full sun in south-facing exposures may cause leaf scorch.

You will find David's Viburnum prefers partial shade in Western Washington, especially afternoon shade in hot exposures to prevent leaf sunburn. The plant grows in average to moist, well-drained soil and tolerates a pH range of 5.5 to 7.0. Consistent moisture produces the best growth; allow the soil to approach dryness only briefly. This evergreen shrub works as a hedge, screen, foundation plant, or mass planting in woodland settings. Blooms on previous season's growth, so prune immediately after flowering to avoid removing next season's flower buds. Watch for viburnum leaf beetle, root weevil, bean aphid, botrytis shoot blight, powdery mildew, and bacterial blight in the PNW. The plant attracts butterflies and birds to fruit in winter, providing wildlife value late in the season.
