About Rayless Daisy (Erigeron aphanactis) Erigeron aphanactis is a species of flowering plant in the daisy family (Asteraceae) known by the common name rayless daisy,:121 or rayless shaggy fleabane. This wildflower is native to the western United States, primarily the Great Basin and Colorado Plateau regions (eastern California, Nevada, Utah, western Colorado, northeastern Arizona, northwestern New Mexico, southern Idaho, eastern Oregon). Erigeron aphanactis grows in sage, scrub, and open woodland habitat. It is a short, clumping perennial with stem and foliage covered in stiff hairs and resin glands. Most of the narrow, fuzzy leaves are near the base of the plant. The erect stems hold inflorescences of one or more flat, buttonlike flower heads, which contain numerous golden yellow disc florets but no ray florets. Each head is about 10 mm (0. 4 inches) wide.
