I went to check out the roots at one of my secret spots, and found an abundance of these bright yellow flowers. Their presence intrigued me. Are they a native species? Are they edible, poisonous, or medicinal? I didn't know really know, so when I came home, I consulted several plant books.
As best I can tell, this plant is called Lomatium Triternatum or Narrow-Leafed Desert-Parsley. It is a native species to this area, and was used for both food and medicine. The roots were ground into flour to make small cakes, and the upper flowers and leaves were sometimes used to treat sore throats and colds.
Does anyone have more information regarding this plant?
