Shepherdia argentea

Common name: Buffalo Berry Family: Elaeagnaceae
Author: (Pursh.)Nutt. Botanical references: 11, 43, 200
Synonyms: Hippophae argentea (Pursh.)
Known Hazards: The fruit contains low concentrations of saponins[101]. Although toxic, these substances are very poorly absorbed by the body and so tend to pass through without causing harm. They are also broken down by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K].
Range: Central N. America - Manitoba to New Mexico.
Habitat: Banks of streams[43] and open wooded areas, often on limestone[101] and on sandy soils[229].

Physical Characteristics

A decidious shrub growing to 4m by 4m at a medium rate. It is hardy to zone 2 and is not frost tender. It is in flower in March, and the seeds ripen from July to December. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). The plant not is self-fertile. It can fix Nitrogen. We rate it 3/5 for edibility and 1/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires dry or moist soil and can tolerate drought. The plant can tolerate maritime exposure.

Habitats and Possible Locations

Hedge, Woodland, Sunny Edge, Dappled Shade.

Cultivar 'Sakakaweja': Hedge, Woodland, Sunny Edge, Dappled Shade.

Edible Uses

Fruit.

Fruit - raw or cooked[1, 2, 11, 61, 161, 257]. It can also be dried and used like currants[3, 46]. A tart but pleasant flavour even before a frost[85, 183], it becomes sweeter after frosts[3, 62, 95]. The fruit is also used for making preserves, pies etc[183]. The fruit should be used in moderation due to the saponin content[101]. The fruit is produced singly or in clusters, it is up to 9mm long and contains a single seed[229].

Medicinal Uses

Disclaimer

Febrifuge; Laxative; Stomachic.

The berries are febrifuge, laxative and stomachic[257]. They have been eaten in the treatment of stomach complaints, constipation and fevers[257].

Other Uses

Dye; Hedge; Soil stabilization.

The plants can be grown as a hedge[160] and windbreak[229].
A red dye is obtained from the fruit[57, 106, 257].
Because it has a wide-ranging root system, forms thickets and is wind tolerant, it is sometimes planted for erosion control[229].

Cultivation details

Succeeds in an ordinary well-drained moisture retentive soil[1, 3, 11]. Tolerates poor dry soils[200] and maritime exposure[182]. Established plants are drought resistant[182].
A very cold-tolerant plant[229].
Plants rarely produce fruit in Britain[11].
Occasionally cultivated for its edible fruit, there are some named varieties[183]. 'Xanthocarpa' has yellow fruits[200].
The fruit is difficult to harvest because the shrub is very thorny[3].
Plants in this genus are notably resistant to honey fungus[200].
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200].
Dioecious. Male and female plants must be grown if fruit and seed are required.

Propagation

Seed - it must not be allowed to dry out[113]. It is best harvested in the autumn and sown immediately in a cold frame. Stored seed requires 2 - 3 months cold stratification[113]. Prick out the seedlings into individual pots once they are large enough to handle. If sufficient growth is made it will be possible to plant them out in the summer, otherwise grow them on in a cold frame for their first winter and plant them out in the following spring or early summer.
Cuttings of half-ripe wood, July/August in a frame sometimes work[113].
