Salal Plant Information
Salal grows in the following 4 states:Alaska, Oregon, California, Washington
Gaultheria shallon is a leathery-leaved shrub in the heather family (Ericaceae), native to western North America. In English, it is known as salal, shallon, or simply gaultheria in Britain.
G. shallon is 0.2 to 5m (0.66 to 16.40ft) tall, sprawling to erect. Evergreen, its thick, tough, egg-shaped leaves are shiny and dark green on the upper surface, and rough and lighter green on the lower. Each finely and sharply serrate leaf is 5 to 10cm (2.0 to 3.9in) long. The inflorescence consists of a bracteate raceme, one-sided, with five to 15 flowers at the ends of branches. Each flower is composed of a deeply five-parted, glandular-haired calyx and an urn-shaped pink to white, glandular to hairy, five-lobed corolla, 7 to 10mm (0.28 to 0.39in) long. The reddish to blue, rough-surfaced, hairy, nearly spherical fruit is 6 to 10mm (0.24 to 0.39in) in diameter.
G. shallon is tolerant of both sunny and shady conditions at low to moderate elevations. It is a common coniferous forest understory species and may dominate large areas. In coastal areas, it may form dense, nearly impenetrable thickets. It grows as far north as Baranof Island, Alaska.Western poison oak is a common associate in the California Coast Ranges.
Its dark blue berries and young leaves are both edible and are efficient appetite suppressants, both with a unique flavor. G. shallon berries were a significant food resource for native people, who ate them fresh and dried them into cakes. They were also used as a sweetener, and the Haida used them to thicken salmon eggs. The leaves of the plant were also sometimes used to flavor fish soup.
More recently, G. shallon berries are used locally in jams, preserves, and pies. They are often combined with Oregon-grape because the tartness of the latter is partially masked by the mild sweetness of G. shallon.
G. shallon was introduced to Britain in 1828 by David Douglas, who intended the plant to be used as an ornamental. There, it is usually known as shallon, or, more commonly, gaultheria, and is believed to have been planted as cover for pheasants on shooting estates. It readily colonises heathland and acidic woodland habitats in southern England, often forming very tall and dense evergreen stands which smother other vegetation. Although heathland managers widely regard it as a problem weed on unmanaged heathland, it is readily browsed by cattle (especially in winter), so where traditional grazing management has been restored, the dense stands become broken up and the plant becomes a more scattered component of the heathland vegetation.
Used for thousands of years by First Nations, the primary non-Aboriginal use in Canada in the 20th century has been as a source of florist greenery, and more recently as a ground cover in landscaping.
Both salal and shallon are presumed to be of Native American origin: the former from Chinook Jargon sallal, and the latter from a native word whose pronunciation was recorded by Lewis and Clark as shelwel, shellwell. The genus Gaultheria was named by Pehr Kalm for his guide in Canada, fellow botanist Jean-Franois Gaultier.
G. shallon has been used for its medicinal properties by local natives for generations. The medicinal uses of this plant are not widely known or used. However, the leaves have an astringent effect, making it an effective anti-inflammatory and anticramping herb. By preparing the leaves in a tea or tincture, one can take the herb safely to decrease internal inflammation such as bladder inflammation, stomach or duodenal ulcers, heartburn, indigestion, sinus inflammation, diarrhea, moderate fever, inflamed / irritated throat, and menstrual cramps. A poultice of the leaf can be used externally to ease discomfort from insect bites and stings.
In the Pacific Northwest, the harvesting of G. shallon is the heart of a large industry which supplies cut evergreens worldwide for use in floral arrangements. It is used in native plant gardens.
