| Viburnum edule: the real deal |
Description
Viburnum edule is a trailing to upright deciduous shrub that can
reach 8 feet in height. New shoots are smooth, green, and sporadically covered
with lenticels; older stems are light brown, maroon, or reddish brown. Leaves
are opposite, 1-4 inches long and often equally as wide with three forward
pointing lobes (occasionally unlobed) and coarsely toothed margins; the lower
surfaces can be sparsely hairy, dull green throughout the spring and summer but
turning yellow to bright red in the late summer to early fall. Flowers are
white and borne in flat topped cymes on lateral branches with 1 pair of leaves. All the flowers are fertile, unlike V. opulus and V. trilobum, which have a peripheral ring of large showy, but
infertile, flowers. Flowers usually bloom from May to July. Fruit is initially
green, then yellow, then assuming streaks of red until it ripens to a solid,
vibrant red color in late August. Fruit are ovate to round, 9-11 mm tall and
8-10 mm wide with a slight dimple at the attachment point. When first ripe they
are firm, but they can persist on the bush for several months and soften with frost.

Viburnum edule is found in the Pacific Northwest from Alaska to northern
Oregon. They are common in Alaska and British Columbia and extend southward
sporadically through the Cascades and foothills to Oregon HWY 20, and are found
to the east in the Columbia range to northeastern Washington, and to the west
along the perimeter of the Olympic Peninsula. Though V. edule is widely distributed throughout the Pacific Northwest, it
is often difficult to locate due to its preference for growing in swamps, the
edges of wet meadows, flood plain forests, and other very wet forests. I
commonly find it with Sitka Spruce, Devil’s Club, and Pacific Yew.

Abe’s Key to Pacific Northwest Highbush Cranberries
1a Leaf petioles lacking glands; leaves with dentate margins and
shallow lobes; flowers all fertile and opening at the same time, cymes
(flower clusters) usually less than 1 inch across with less than 50
flowers, on lateral branches with only 1 pair of leaves; fruit borne in
small clusters (usually less than 10), sour but very palatable; reclining
to upright shrub rarely exceeding 7 feet tall, inhabiting wet forests,
swamps, and lakeshores:
– Viburnum
edule Highbush Cranberry, Squashberry, Mooseberry.
1b Leaf petioles with glands near the base of the leaf blade; leaves
deeply lobed with +/- dentate margins; cymes 2-3 inches across with a
marginal ring of larger sterile flowers (3/4 inch across) that open before
the central fertile flowers (1/4 inch across), on terminal branches with 2
pairs of leaves; fruit borne in large clusters (usually more than 10);
shrubs 8-15 feet tall – Go to 2.
2a Petiole
glands convex, slightly stalked (may become deformed or shrink as the
season progresses); petiole groove broad and shallow; stipules small and
deciduous; leaves larger at 2-4 inches across with sharply pointed lobes
with scattered to no dentations on the margins; underside of the
leaves pubescent.; fruit sour but edible; limited in our area to
eastern British Columbia (and possible the lower Fraser River valley):
– Viburnum
trilobum, Viburnum opulus
var. americanum, American
Highbush Cranberry, American Cranberrybush.
2b Petiole
glands concave, sessile; petiole groove deep and narrow; stipules long,
conspicuous and persistent; leaves smaller at 1-3 inches across with more
rounded lobes and more dentate margins; pubescence usually limited to the veins on the
underside of the leaf; fruit bitter, sour, and mildly toxic; growing
throughout our area in or near urban areas and old fields:
– Viburnum
opulus var. opulus,
European Highbush Cranberry, European Cranberrybush, Guelder Rose, Cramp
Bark, Snowball Tree.

Ethnobotany
Viburnum edule berries don't appear in the ethnographic record very far south of the Puget Sound. They were not commonly eaten by the Coast Salish and Erna Gunther did not include them in the Ethnobotany of Western Washington, although George Gibbs did record a Nisqually name for the berries (1877). Along the Fraser River, the Squamish and Sto:lo have names for the plant and likely picked the fruit, but the ethnographic record is sparse (Turner and Bouchard 1976; Galloway 1982). Further upriver, the Nlaka'pamux (Thompson) traditionally ate the fruit fresh, dried, or cooked into a soup or made into jelly (Turner et al. 1990). Just over the Cascades the Okanagan and Colville traditionally harvested the berries after a frost and ate them fresh (Turner et al. 1980). The more northern Salish on eastern central Vancouver Island collected Highbush Cranberries, and often cooked and served them with oil at large feasts, or ate them raw after a frost had softened the fruit (Turner and Bell 1971). On the other side of Vancouver Island, the Nuu-chah-nulth ate the berries fresh with grease (Turner and Efrat 1982). Northward, the Kwakwaka’wakw steamed partially unripe berries until they became soft and red and stored them in bentwood boxes filled with water and sealed with grease for family use throughout the winter. Only ripe, fresh cranberries served with eulachon grease were eaten at feasts (Turner and Bell 1973). All the Indigenous groups on the North Coast of British Columbia traditionally use the berries. Hanaksiala and Haisla families owned productive bushes and stored the berries in water filled barrels sealed with grease for winter use. They were sometimes prepared with Crabapples (Malus fusca), Kinnikinnick (Arctostaphylos uva-ursa) berries and the False Solonomon’s Seal (Maianthemum racemosum) juice (Compton 1993). The Gitga’at use the berries extensively. They were traditionally stored in barrels or boxes filled with water or whipped grease and served at feasts throughout the winter, often with Crabapples (Malus fusca) and today people make jam or jelly from the fruit. According to Ernie Hill Jr., if the berries are carefully simmered for many hours, the seeds will separate from the pulp and float to the surface where they can easily be skimmed off the top (Turner and Thompson 2006). Further north along the coast, the Haida hold these berries in high esteem. Berry patches were traditionally owned and managed by families and permission was needed to pick from these productive areas. Slightly under-ripe berries are often picked and canned, or in historic times, placed in bentwood boxes filled with water and sealed with grease for use in the winter. The berries are frequently mentioned in Haida mythology are believed to be the food of supernatural beings (Turner 2004). Viburnum edule are similarly used by the Iñupiat in Northwest Alaska, who occasionally eat them seeds and all (Jones 1983)

Many Indigenous People
believe that the plants are becoming scarcer, possibly on account of higher
deer populations (deer over-browse the vegetation (see Turner 2004)), lower
bear populations (bears break limbs off the bushes, stimulating new growth (see
Compton 1993)), and the disruption of traditional management practices.

| The seeds of V. edule are flat like those of squash |
Other common names for Viburnum edule include Mooseberry
(because the shrubs are universally loved by North American ungulates) and
Squashberry (because the flat seeds resemble those of squash). Whether by beast
or human, the plants are definitely deserving the specific epithet edule, which means “edible” in Latin.
