Southwest Stoneseed
Many-Flowered Stoneseed


General Description:
This plant is large and bushy with numerous, drooping, deep yellow flowers that are narrow with trumpet-shaped corollas having five smooth-edged lobes. The leaves are slightly hairy, narrow, and light to medium green in color. Stoneseeds belong to the borage family. This species can be easily confused with the Showy Stoneseed, Lithospermum incisum. The most obvious distinction is that the Showy Stoneseed is often a smaller herb with fewer stems and flowers.

Plant Lore
Native Americans used the roots to make a purple dye for clothing and feathers. The seeds are hard, shiny, and white, hence the name stoneseed. Some sources claim that stoneseed plants were also used as a contraceptive and to treat diarrhea.
