Shrubs, 20–40 cm (branches widely spreading), mildly aromatic; root-sprouting (caudices stout). Stems gray (coarse, brittle), hairy (bark gray, exfoliating). Leaves deciduous, silver-gray (rigid); blades broadly spatulate, 1.5–4 × 0.5–0.7 cm (bases narrow), 3-lobed (lobes 1/2+ blade lengths, ca. 1 mm wide), faces densely hairy. Heads borne singly or (in glomerules) in (densely leafy) spiciform or paniculiform arrays 2–20 × 2 cm. Involucres narrowly campanulate, 4–5 × 2.5–3.5 mm. Phyllaries elliptic (acute to obtuse), densely canescent. Florets 4–8; corollas yellowish red to red, 2–2.8 mm (style branches oblong, truncate, exsert). Cypselae (4–5-ribbed) 1–1.5 mm, glabrous. 2n = 18, 36. Shrubs, 20–40 cm (branches widely spreading), mildly aromatic; root-sprouting (caudices stout).
