The rusty scales and star-like clusters of scales make this a very distinctive shrub. All the members of the Oleaster family have these unique scale-like coverings on leaves and twigs. In riparian areas there are several other species with which you could confuse buffaloberry. Shepherdia species have opposite leaves, Elaeagnus have alternate leaves. Silver buffaloberry(Shepherdia argentea)- is armed with thorns; Silverberry or Wolf Willow(Elaeagnus commutata)- has strong sweet scented flowers, alternate leaves, brownish twigs, and silvery, dry, mealy berries; Russian Olive(Elaeagnus angustifolia) is taller and can be a tree. It has long narrow leaves and silvery surfaces of the twigs Most members of this family have these unique scales and hairs.

Did You Know?:

Buffaloberry is listed as endangered in Pennsylvania, Maine and Illinois. It was also found in Indiana but has been extirpated. This shrub quickly re-establishes after fire. It fixes nitrogen using symbiotic root bacteria, which helps explain its ability to grow in tough nutrient-poor sites, such as immediately following deglaciation or in active river channels. Buffaloberry is a plant that is recognized as being useful for a variety of purposes, as well as having the distinction of being valued as a form of commerce, which truly elevates this species as being one of profound importance to primitive human societies and sojourning frontier-people alike. Its cross-continental abundance also helped to shoehorn the plant into the cultural and societal history of a country bound to its natural resources- this fact alone may have saved many a life when times got thin. name "buffaloberry" has origins either in the Great Plains bison who grazed plant heavily or because it was eaten commonly as garnish for buffalo steaks and tongues in the early days; name "soopalallie" is Chinook indian language meaning soap (soop) and berry (olallie) because berry pulp is soapy to the touch, ; name "hooshum berry" comes from the Athapascan word for this plant; some tribes called it "stinkwood" for the horrible odor that was released when burned; Shepherdia is named for English botanist John Shepherd (1764-1836)


Food: berries eaten fresh, or boiled, caked and dried for future use, now preserved by canning or freezing; berries become foamy when beaten because juice is rich in a bitter substance called saponin; berries were mixed with water and whipped to make a white-to-salmon colored foamy dessert called "Indian ice cream", usually sweetened with other berries or sugar because it was so bitter; also added to stews or cooked to make syrup, jelly or sauce for buffalo steaks; soapberry juice mixed with water and sugar makes a refreshing "lemonade"; used as emergency food because the berries were so abundant. Berries were collected by beating branches over canvas or hide with a stick; Medicine: rich in vitamin C and iron; taken to treat flu and indigestion; made into tea for relieving constipation; soapberry "lemonade" was said to cure acne, boils, digestive problems and gallstones; bark was made into tea as a solution for eye ailments; twigs boiled as a laxative tea; soapy berries were crushed and boiled and used as soap; whole plant used traditionally as medicine, treated everything from heart attacks to indigestion; berries also chewed by women to induce birth. Other: berries were an important trade item throughout their range and today are still valued as gifts.
