Perennials, (15–) 20–60 (–70) cm (mat-forming), sometimes faintly aromatic (rhizomes creeping, relatively thin). Stems 1–3, erect or ascending, white, simple (stout), densely tomentose to floccose. Leaves basal and cauline (petiolate), silver-gray; blades oblanceolate, (proximalmost) 3–10 × 1–5 cm, pinnatifid (lobes relatively broad, rounded; distal leaves, on flowering-stems, smaller), faces densely tomentose. Heads (erect or spreading, peduncles 0 or to 3 mm) in dense, paniculiform, racemiform, or spiciform arrays 8–20 × 2–4 cm. Involucres broadly campanulate, 5–8 × 6–7 mm. Phyllaries broadly lanceolate, tomentose. Florets: pistillate 12–16; bisexual 25–30; corollas yellow (narrow or tubular), 3.2–4 mm (unusually large), glabrous or sparsely hairy (style-branches prominent, erect, blunt). Cypselae (dark-brown) narrowly oblong-linear (slightly flattened, smooth), 3–4 mm, glabrous. 2n = 18.

Discussion

Artemisia stelleriana is apparently native along the western tip of the Aleutian islands (D. F. Murray, pers. comm.). It is an attractive ornamental and, in parts of its range in the flora area, it appears to have escaped from cultivation and is naturalized in beach dunes and other sandy habitats.
