Viburnum davidii of David Viburnum is a showy evergreen shrub valued for its glossy dark green leaves and metallic turquoise blue fruit. This is a wonderful foundation shrub, especially when it is used with ferns, azaleas, and other acid loving plants.
Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. This plant requires well drained soil that is rich in organic matter. Best results will be obtained if you feed with an acid fertilizer after bloom and you keep the roots cool with a thick layer of mulch. Pruning time is late winter or early spring.
This shrub is winter hardy to Zone 7 (will withstand temperatures that can dip as low as 0 degrees) where it is easily grown in average, medium moisture, well-drained soils in partial shade to full sun (if watered appropriately). Best growth occurs with consistent and even moisture. This is an evergreen shrub, but it tends to be semi-evergreen to deciduous near the far northern edge of its growing range. Plants generally appreciate some afternoon shade in hot summer climates. This shrub is dioecious (separate male and female plants). Female plants need male pollinators in order to bear fruit.
David viburnum is a compact, rounded, evergreen shrub that typically grows in a mound reaching a height of 2-3′ tall and a width of 3-4′. It produces small white flowers in showy rounded clusters (cymes to 2-3″ wide) bloom in spring. Fertilized flowers on female plants give rise to showy round fruits that emerge green but change to pink, red and finally a metallic turquoise blue as they ripen. Fruits usually persist on the shrub into winter months. Fruits are attractive to birds. Leathery, deeply-veined, elliptic-oval, blue-green leaves (to 3-6″ long) are evergreen.
No serious insect or disease problems. Leaf scorch may occur in hot full sun locations (if you are going to locate this plant in direct sun you will have to water more frequently).
It makes a great informal hedge, can be used as a foundation plant, or it is also great in borders or open woodland areas. Spring flowers, fall fruit and evergreen foliage make this an interesting and attractive landscape shrub.
