Found in waste areas, pastures, roadsides
Seen blooming on September 25, 2018 by CR 74  in Chamita
Not all the yellow flowers growing in profusion along our roadsides are sunflowers and chamisa. Another erect, often tall, showy sunflower-like plant is the Golden Crownbeard. It grows to 3 feet tall with fine white hairs on stem, underside of leaves and bracts. The leaves are gray-green, triangular and toothed. Leaves and flowers are smelly. The flower heads are up to 2" across with yellow centers and yellow petals that have three teeth at the tip. The Hopi and Navajo make the plant into tea and use it as a fever wash and to treat spider bites. The Navajo also use a liquid of strained leaves for stomach trouble, chew petals for good luck in hunting and wear the flowers in a hat band as protection from lightning. Source.
