Balsamorhiza deltoidea is a species of flowering plant in the sunflower tribe of the plant family Asteraceae known by the common name deltoid balsamroot. It is native to western North America from British Columbia to California, where it grows in many types of generally mountainous habitat.
Balsamorhiza deltoidea is a taprooted perennial herb growing erect to a maximum height near 90abbr=offNaNabbr=off. The stems are hairy and glandular. The large leaves are up to 25abbr=offNaNabbr=off long and 20cm (10inches) wide, and are roughly triangular in shape, hairy and glandular, and often toothed along the edges.
The inflorescence bears usually one or sometimes a few large flower heads, each lined with hairy, pointed phyllaries up to 4abbr=offNaNabbr=off long. The head has a center of yellowish disc florets and a fringe of pointed yellow ray florets each up to 4or long. The fruit is an achene 7to in length.
Deltoid balsamroot has been used as a food and medicinal plant by Native Americans. The seeds were eaten raw or cooked, and sometimes ground up and made into breads or cakes. The roots were also eaten, either raw or cooked, and when roasted make a coffee substitute. Young shoots were also eaten as a fresh green. The roots were also used to treat colds.
