  form2 form Form

-medium-sized ornamental shrub

-maturing at about 8' tall x 10' wide

-layered vased growth habit in youth, becoming more layered horizontal with age

-medium growth rate

foliage2 foliage Foliage

-medium to dark green, opposite, ovate to elliptical, serrated, with impressed veins and a pubescence on the petiole and lower leaf surface

-foliage will diurnally wilt during the driest portions of summer

-autumn color is usually an attractive wine, maroon, or burgundy color, and persistent for 2-4 weeks in mid- to late autumn

Flowers
flowers

-white, in early May, atop 2" long peduncles above the angled stem plane and also in a "double file" on either side of the stem, effective for 2 weeks

-flat-topped fertile inflorescences are creamy-white, to 3" in diameter, and open shortly after the more showy outer ring of sterile flowers open first; one of the most showy shrubs when in flower

Fruit
fruit

-shrubs often do not set fruit due to a lack of appropriate cross-pollination, but when fruits do occur, they transition from green to pink-orange-red in mid-summer, mature to black by Sept., and then either abscise or are consumed by the birds

Twig
twig

-brown, pubescent to tomentose, with winter vegetative and floral buds somewhat elongated and pressed closely to the primary stems, with the floral buds slightly swollen and distinctly valvate

Trunk

-older branches develop fissuring bark as they mature into several main trunks; this is more pronounced on the larger "species" form, namely, Viburnum plicatum

Culture

-full sun to partial shade

-performs best in partial sun in evenly moist, well-drained, slightly acidic soils; quite adaptable to soils of various pH, but not especially adaptable to poor soils, compacted soils, heavy clay soils with poor drainage, heat, drought, and pollution

-Honeysuckle Family, with no pests causing significant problems, but a branch canker on old, mature plants is the primary disease of concern, causing individual branches to die back to the ground

-commonly available, primarily in B&B form

Hardiness

-zones 5 to 8

Origin

-native to China and Japan

U   S   A   G   E
 

Assets

-extremely showy white inflorescences in mid-spring, arranged in doublefile fashion alongside the main stems and above the stem planes

-excellent vased to horizontal branching habit

-good burgundy autumn color

Liabilities

-basal trunk canker can arise on individual branches with advanced age, causing them to die one-at-a-time

-marginally hardy in severe zone 5 winters, and best placed in a wind-protected site in zone 5 for this reason

-foliage will diurnally wilt during the driest portions of summer

Function

-single, dual, or group planting shrub for entranceways, foundations, raised planters, naturalized shrub borders, or as a specimen

Texture

-medium texture in foliage and when bare

-thick density in foliage and when bare
