Ericameria discoidea grows in clumpy thickets on rocky slopes. It is a small shrub reaching a maximum height of 40 centimeters (16 inches). It has many erect branches covered in a foliage of oval-shaped leaves coated in dense white woolly fibers and tiny stalked resin glands. Atop each short branch is an inflorescence of many flower heads, each packed with sometimes as many as 70 disc florets that bloom in golden yellow and wilt to a rusty orange. There are no ray florets.{{Cite web |title=Ericameria discoidea in Flora of North America @ efloras.org |url=http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250066517 |access-date=2023-10-30 |website=www.efloras.org}}
