Flamboyant white flowers are scattered across a sagebrush plain. Prickly poppy, or Argemone munita, has the large papery-thin petals–stark white around a brilliant yellow center. Insects flock and feed among the many yellow stamens. The whole plant has abundant gray-green leaves that are prickly to the touch, and stands as tall as my knee. It is truly a beauty! But you won’t see it in the Bay Area; it grows across the west but only between 4,000 and 8,500 feet. If you see a similar flower at low elevation, you’re probably looking at one of this bloom’s lovely cousins, such as the Matilja poppy.
