Grindelia nana is one of the smaller members of this genus, not exceeding two feet. It occupies low to medium elevations, from near sea level to 5,500 feet. Stems are erect or leaning, freely branching, and bear many large, thick leaves, which are hairless and dotted with tiny resin glands. Leaf color ranges from yellowish green to greyish green. Leaves usually have quite large teeth along the edges.
Phyllaries are light green in color, round in cross-section, relatively widely separated, and recurved by up to 360 degrees. They are also resinous. The lower ends of the phyllaries are quite thick. The flowerheads have between 11 and 28 ray florets, between 0.5 and 1 inches in length. The center contains several dozen ray florets. Both rays and discs wither to brown.
