Dyssodia acerosa (Thymophylla acerosa)
Prickleleaf dogweed ranges from West Texas, south into Mexico and north through Arizona and New Mexico into Utah and Nevada, growing on dry rocky hillsides at 3500-6000 feet. The base of its stems are woody, the upper portion being herbaceous and annual, bearing tiny pointed leaves and dime-size golden yellow daisy flowers. Although this diminutive beauty is a short-lived perennial, where it is grown in full sun on dry, gravelly well-drained soil it will seed out to produce an ever-expanding area of lacy summer color.
