Description

General: Honeysuckle family (Caprifoliaceae). Native shrubs growing 1-3 meters tall, with arching branches forming an overall rounded crown, sometimes spreading up to 2.5 meters; twigs slender, ridged and angled. Leaves deciduous, opposite, simple, oval to oblong, obovate, or elliptic, 4-10 cm long, with coarsely but regularly toothed margins, shiny dark green above, paler beneath, at least sparsely stellate-pubescent beneath and on the petioles, turning yellow to red or reddish-purple in late fall. Flowers are 5-8 mm wide, white, in flat-topped clusters 5-8 cm broad. Fruits ovoid, berry-like (drupes), 5-8 mm in diameter, bluish-black. The common name refers to the Native American use of the straight young stems as arrow shafts. © Hugh Wilson Vascular Plant Image Gallery Texas A&M University, Bioinformatics Working Group Variation within the species: Leaves of V. dentatum are stellate-pubescent in variable density on the lower surfaces and petioles. Localized geographic variants are often evident over the range of the species, with leaf shape and size often more consistent on a local or regional level than the type of vestiture. A number of varieties have been recognized – but these distinctions apparently have not been recognized among the horticultural forms. V. dentatum var. deamii (Rehd.) Fern. V. dentatum var. venosum (Britt.) Gleason V. dentatum var. indianense (Rehd.) Gleason V. dentatum var. lucidum Ait. (= V. recognitum Fern.) V. dentatum var. scabrellum Torr. & Gray (= V. scabrellum (Torr. & Gray) Chapm.) Viburnum recognitum has the leaves completely glabrous or sparsely strigose with simple hairs along the veins and petioles, commonly with tufts of soft, white hair in the vein axils of the lower surface. With V. dentatum, V. recognitum ranges from Texas to New England, but V. recognitum is the common form in the northern part of the range, V. dentatum in the southern part. Viburnum scabrellum is a form with broader, rougher leaves and primarily occurs in the southern part of the V. dentatum range.

Distribution

The Viburnum dentatum species complex is widespread in the eastern United States, from Maine to Florida and westward to Iowa and east Texas. For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site.

Adaptation

Open woods and margins, streambanks. Arrow-wood viburnum prefers loamy, neutral to acid soil with ample moisture, but is adaptable to a range of conditions from dry to fairly wet soil. Plants are salt-tolerant in New England coastal areas. The can grow in generally drier conditions than V. acerifolium. They most commonly occur in partial shade but can be grown in full sun. Flowering May-June; fruiting August-November.

Establishment

Plants may begin to produce fruits by the third year. Fruits apparently are consistently formed every year. Like related species of Viburnum, the seeds of V. dentatum probably have a cold requirement for breaking embryo dormancy. Vegetative reproduction is through short rhizomes and sprouts from the root crown.

Management

Plants of arrow-wood viburnum are propagated from cuttings or seed. They are easily transplanted and free from serious problems of disease or insect pests (with the caveat below). Occasional pruning is helpful in rejuvenation and shaping. Prune off basal suckers to restrict spreading if necessary. Viburnum leaf beetle: The viburnum leaf beetle (Pyrrhalta viburni), native to Europe and Asia, was first encountered in North America in 1947, perhaps arriving earlier from Europe on nursery plants. It received little notice until 1978, when it caused severe defoliation of ornamental viburnums in Ontario and Quebec. It has now reached western New York and Maine and become a concern in urban landscapes and nurseries. The adult and the larva “skeletonize” leaves by feeding on the leaves between the midrib and larger veins. Plants, which have been defoliated for 2-3 consecutive years, may be killed. The preferred host is Viburnum opulus and its selections; lesser damage is caused to V. lantana and V. rafinesquianum, V. dentatum, V. acerifolium, and V. lentago. Other species, particularly V. rhytidophyllum and V. carlesii, are relatively unaffected. The entire life cycle of the viburnum leaf beetle takes about 8-10 weeks. Larvae hatch in early May and feed on the viburnum leaves throughout the larval period, which lasts 4-5 weeks. The larvae pupate in the soil. The adults (4.5-6.5 mm long, brown) appear by mid-July and continue eating the leaves, then mate and lay over-wintering eggs on the twigs. Egg-laying holes are in a straight line on the underside of the current season's growth. Chemical control of the viburnum leaf beetle is best applied to young larvae, because adults will fly away or drop to the ground if disturbed. If over-wintering egg sites are found, affected wood should be pruned and destroyed before the eggs hatch. Examine upper and lower leaf surfaces for feeding larvae. Potential biological control mechanisms are being studied. Cultivars, Improved and Selected Materials (and area of origin) These plant materials are somewhat available from commercial sources.

Fact Sheet

Alternate Names

V. dentatum L. var. dentatum is a variation occurring within the Viburnum dentatum species. Arrow-wood viburnum, southern arrow-wood, roughish arrow-wood. (Arrowwood is frequently hyphenated: arrow-wood.) The common name refers to the Native American use of the straight young stems as arrow shafts.

Uses

Landscape: V. dentatum is an adaptable native, multi-stemmed shrub. Creamy white flowers, dark blue berries and colorful fall foliage make southern arrowwood an attractive landscape plant. It suckers freely from the base. It can be used for borders or screens or as mass plantings and groupings to attract birds, which eat the fruit. Medicinal: Viburnum species have been used for numerous medicinal purposes (Alternative Medicine Foundation: HerbMed, 2000--for notes and internet links on medicinal use and other health related topics for Viburnum species).

Status

Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values).

Description

Southern arrowwood is a native shrub growing 3-9 feet tall and spreading sometimes up to 8 feet. The plant’s arching branches form an overall rounded crown; twigs are slender, ridged and angled. Its leaves are deciduous, opposite, simple, oval to oblong, obovate (inversely egg-shaped), or elliptic in shape and 1½ - 4 inches in length, with coarsely, but regularly, toothed margins. Leaves are shiny dark green above and paler beneath, sparsely stellate (with hairs in small star-like tufts) on undersides and petioles. Foliage turns yellow to red or reddish-purple in late fall. Small white flowers are borne in 2 to 4-inch flat-topped clusters in May to early June. The ¼ inch berry-like drupes are bluish-black and attractive to wildlife. Fruiting occurs from August - November. © Hugh Wilson Vascuclar Plant Image Gallery Texas A&M University, Bioinformatics Working Group Localized variations of southern arrowwood occur over the geographic range of the species. Most common differences between the variants are in the shape and size of leaves, the type and placement of pubescence (hairs) on the leaf underside and petioles, and the region of occurrence. Some variations of southern arrowwood include V. dentatum var. dentatum; V. dentatum var. scabrellum Torr. & Gray (= V. scabrellum (Torr. & Gray) Chapm.) and V. dentatum var. venosum (Britt.) Gleason.
