  form Form

-large, semi-evergreen, broad-leaved ornamental shrub or foliage shrub

-maturing at about 12' tall x 12' wide, although sometimes larger

-upright columnar growth habit in youth, becoming more rounded and spreading with age

-medium to rapid growth rate

foliage2 foliage Foliage

-dark green above while much paler white-green beneath, being semi-evergreen, leathery, thick, and having a rough texture with sunken veins above, with prominently large veins beneath that have a reticulate branching pattern

-leaves are opposite, narrowly ovate to oblong, lightly serrated or entire, with an acute apex and cuneate to cordate base above a thick petiole, about 3-4 times as long as they are wide, and often in a tattered and ragged semi-evergreen state by early winter

-autumn color is dark green and slowly absiscing, with the foliage remnants becoming wind burned and a very unnattractive brown-green during the winter

Flowers
flowers

-green-cream, creamy-white, or cream-brown (due to damage by late frosts) flat-topped inflorescences occur up to 4" in diameter, in late Apr. and early May, being present for about 2 weeks but not showy in spite of their large size

-floral buds are set by mid-summer (as are most shrubs) and may sporadically open in late summer and early autumn

Fruit
fruit

-at first green, then transitioning to red, red-orange, or red-yellow by mid-summer, then maturing to black in late Aug. and early Sept.

-often sparse or non-existent

Twig
twig

-emerging green-white, stout, and strongly scurfy-pubescent, but changing to a noticeable orange-brown by winter

-winter buds are large; floral buds are prominent terminal knobs, while vegetative buds are naked and much elongated, with terminal vegetative buds much larger than the lateral buds

trunk Trunk

-strongly multi-stemmed to multi-trunked, bold-textured, and very stout, with heavy branches only slightly arching with age, and old leggy trunks being supplemented with rapidly-growing basal suckers with age

Culture

-full sun to partial shade

-adaptable to poor soils, compacted soils, soils of various pH, dry soils, drought, pollution, and heat

-propagated by rooted stem cuttings

-Honeysuckle Family, with no serious pest or disease problems, except for occasional cosmetic leaf spot

-commonly available in B&B form

Hardiness

-zones 4 to 8

Origin

-parents of this hybrid are Wayfaringtree Viburnum (Viburnum lantana, native to Eurasia) and Leatherleaf Viburnum (Viburnum rhytidophyllum, native to China)

Assets

-outstanding summer foliage (leathery, dense, and dark green)

-striking bold texture (best displayed when in summer foliage)

-urban tolerant, with vigorous growth

-semi-showy green-white flowers in spring

Liabilities

-semi-evergreen foliage is tattered, wind burned, and unattractive throughout much of the winter

-easily gets out-of-bounds due to its vigorous growth

legginess with age, in part hidden by the basal suckers

-inflorescences may sporadically open in summer or early autumn (some consider this an asset)

Function

-formal or informal hedge, border, entranceway, spacious foundation, utilitarian, or deciduous screen shrub, being the boldest-textured Viburnum

Texture

-bold texture when in foliage, semi-evergreen, or nearly deciduous

-thick density in foliage but average density otherwise
