(near Horselake, Chelan County, Washington) Balsamorhiza sagittata is a North American species of flowering plant in the tribe Heliantheae of the family Asteraceae known by the common name arrowleaf balsamroot.
[4] This is a taprooted perennial herb growing a hairy, glandular stem 20 to 60 centimetres (7+3⁄4 to 23+1⁄2 inches) tall, with the plant's total height up to 80 cm (31 in).
[5] The plant's native range extends from British Columbia and Alberta in the north, southward as far as northern Arizona and the Mojave Desert of California, and as far east as the Black Hills of South Dakota.
[18] Many Native American groups, including the Nez Perce, Kootenai, Cheyenne, and Salish, utilized the plant as a food and medicine.
[20] In 1806, William Clark collected a specimen near the White Salmon River, and both he and Frederick Pursh noted that the stem was eaten raw by the American natives.
