General: Honeysuckle family (Caprifoliaceae). Native shrubs to 4 m high, with upright, spreading, arching branches. Leaves deciduous, opposite, ovate, 5-12 cm long, deeply 3-lobed, coarsely toothed, with 1-6 large glands near the petiole apex, becoming yellow-red or reddish-purple in the fall. Flowers white, in flat-topped clusters 7-10 cm broad, with flowers of two different types, those in the outer ring sterile, showy, with expanded corollas 1-2 cm broad, the inner flowers much smaller, fertile, with yellow anthers. Fruit berry-like (a drupe), globose, bright red, 8-10 mm in diameter; stone single, strongly flattened. The common name alludes to the resemblance in fruit between the highbush cranberry and the cranberry of commerce (Vaccinium macrocarpon).
Variation within the species.
The North American plants have generally been recognized as the same species as the closely similar native of Europe, northern Africa, and northern Asia – V. opulus L. [var. opulus]. Var. opulus is said to differ from the American variety in its filiform-attenuate stipules and petiolar glands mostly short-pedicellate, round-topped to concave, and mostly wider than high. Voss (1996) notes that “variation between vars. opulus and americanum is too great – and too continuous – to make clear distinctions.” Variants have not generally been recognized from within the American segment of the species, but horticultural selections have been made from plants of both continents, primarily for leaf color, fruit color, and growth habit. The best known of these is the cultivated “snowball bush” (V. opulus var. roseum), a form developed from Old World plants, with spherical inflorescences of enlarged, completely sterile flowers (the "snowballs").
The native variety (var. americanum) is known to hybridize with cultivated or escaped ornamental forms of var. opulus. This may result in the gradual degradation or loss of the native genotype.
Distribution: Var. americanum is widely distributed across north-central North America, from Newfoundland, Nova Scotia, New Brunswick, and Quebec to British Columbia, and in the US from Maine to Pennsylvania and West Virginia, northwestward to Washington. For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site. The non-native var. opulus is frequently planted and sometimes escapes; it is recorded from Ontario and New Brunswick and various states in the northeastern quarter of the US – Maine to Virginia and West Virginia, westward to Wisconsin, Iowa, and Missouri.

Cultivars, improved and selected materials (and area of origin)
These plant materials are somewhat available from commercial sources. Native plant cultivars with superior fruit and processing characteristics are available (for example: “Andrews,” “Hahs,” “Hogg's Red,” “Manitou,” “Phillips,” and “Wentworth”). The processed fruit is very similar to cranberry (Vaccinium macrocarpon) and red currant (Ribes rubrum).
Contact your local Natural Resources Conservation Service (formerly Soil Conservation Service) office for more information. Look in the phone book under ”United States Government.” The Natural Resources Conservation Service will be listed under the subheading “Department of Agriculture.”
Highbush cranberry is easy to grow, adaptable to a variety of soil and acidity, but it does best in consistently moist but well-drained soil. A yearly application of compost or well-rotted manure will maintain growth and fruit yields The plants are shade-tolerant, but flowering, fruiting, and foliage color will be best on plants in full sun. Plants may require occasional pruning to keep them from becoming leggy and to encourage the production of new shoots; prune immediately after flowering. Highbush cranberry can be propagated through hardwood and softwood cuttings, layering, crown division and by seed. Take softwood cuttings in mid-June through early-July for easiest rooting.
Var. americanum is relatively -free from insect and disease damage in cultivation although bacterial leaf spot, powdery mildew, shoot blight, tarnished plant bugs, stem borers, and thrips will occasionally be a problem.
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.
Relevance to Humans and Ecosystems
Ethnobotanic: The bark of highbush cranberry yields a powerful antispasmodic (whence the origin of one its American common names, crampbark). The water-soluble preparation (containing a bitter compound called viburnine) has been used for relief of menstrual and stomach cramps and asthma. The antispasmodic properties apparently were discovered independently by European, Native American, and Asian peoples. The action of this agent from highbush cranberry closely resembles that of black haw (Viburnum prunifolium).
Highbush cranberry is used as an ornamental plant and valued for its edible fruits. The fruit is commonly gathered from wild stands in late August or early September, best when picked slightly under-ripe (and sour), and used in sauces, jellies, and juices. If picked after a heavy frost, the fruit are softer and more palatable but they develop a musty, somewhat objectionable odor during cooking. The species has never developed into a commercial fruit crop.
Wildlife: The bright red fruits often persist on the plants throughout the winter, good for ornamental value but suggesting that they may not be especially palatable for wildlife. Still, they are known to be eaten by deer, moose, foxes, raccoons, chipmunks, squirrels, skunks, mice, rabbits, grouse, pheasants, robins, cedar waxwings, and other songbirds. They are not normally eaten by birds until after they have frozen and thawed several times.
The native (American) plants of this species (= V. trilobum = V. opulus var. americanum, see below) are hardier as ornamentals, less susceptible to aphid attack, and have more intense fall color than the Eurasian plants, and they produce edible fruit. Fruit of the European plants tends to be bitter, and cultivars derived from the European species are grown strictly as ornamentals.
Viburnum trilobum (American Cranberrybush Viburnum, American Cranberrybush, Kalyna or Highbush or High Bush Cranberry) is a species of Viburnum native to northern North America, from Newfoundland west to British Columbia, south to Washington state and east to northern Virginia. It is very closely related to the European and Asian Viburnum opulus, and is often treated as a variety of it, as Viburnum opulus L. var. americanum Ait., or as a subspecies, Viburnum opulus subsp. trilobum (Marshall) Clausen.
It is a deciduous shrub growing to 4 m tall. The bark is gray and rough and has a scaly texture. The stems arch and are very dense, and the twigs are a reddish-brown color. The leaves are opposite, three-lobed, 6-12 cm long and 5-10 cm broad, with a rounded base and serrated margins; they are superficially similar to many maple leaves, most easily distinguished by their somewhat wrinkled surface with impressed leaf venation. The leaf buds are green. The bud scales are valvate. The flowers are white, produced in corymbs up to 13 cm diameter at the top of the stems; each corymb comprises a ring of outer sterile flowers 2-2.5 cm diameter with conspicuous petals, surrounding a center of small (5 mm), fertile flowers; the flowers are pollinated by insects. The fruit is an oblong red drupe 15 mm long and 12 mm broad, containing a single flat, white seed. Plants begin to produce fruit at approximately five years of age; when animals, including birds, eat the fruits, they deposit the seeds in another location in their droppings.
Although often called "Highbush Cranberry", it is not a cranberry. The name comes from the red fruits which look superficially like cranberries, and have a similar flavor and ripen at the same time of year. The fruits, sour and rich in vitamin C, can be eaten raw or cooked into a sauce to serve with meat or game.
Pests and diseases
This is a commonly used berry in Western Canadian cultures. Peoples of various origins both Native and European have used the berries for many years.
The Canadian French name for the berries is Pembina. The name Pembina was then applied to two rivers, one in Manitoba and North Dakota, and one in Alberta, and from the rivers the named was applied to several other places and institutions.
The Ukrainians call the berry Kalyna, which is now the name of an ecomusem in Alberta, Kalyna Country.
