Found in dry open areas and slopes
Seen blooming in July in Poshuouinge, Santa Fe NF
​
Rubberweeds grow less than a foot tall with leafy stems and many, bright yellow flowers. The leaves are divided into narrow segments. Flower heads usually have 8 petals, but can have more, and are about ¾ inch across. The petals have three-toothed tips and droop when the plant ages. The flowers provide a yellow dye for wool. Hopi and Navajo used the bark of the roots as a chewing gum, due to the roots having a milky sap that contains latex. The stems/leaves were also used to make a tea and a poultice used to treat wounds. It was also used by the Navajo as an emetic in the Evil Way ceremony. It is toxic to livestock. Source.
