Perennials, 50–170 (–200) cm, aromatic (rhizomes woody, coarse). Stems usually 10+, erect, light-brown, simple, usually glabrous. Leaves cauline (sessile), bicolor (white and dark green); blades lanceolate, 5–10 (–15) × 1–5 cm (bases strongly tapered, attenuate), coarsely and irregularly lobed, faces tomentose (abaxial) or glabrous (adaxial). Heads (erect) in crowded (proximally leafy), paniculiform or racemiform arrays 17–30 × (2–) 4–5 cm (lateral branches stiff, erect). Involucres narrowly turbinate or globose, 1.5–2.5 × 1–1.5 mm. Phyllaries (straw-colored to yellow-green, shiny) lanceolate, glabrous or sparsely hairy. Florets: pistillate 2–5; bisexual 2–7; corollas yellow, 1.5–3 mm, glabrous. Cypselae ellipsoid, 0.8–1.5 mm, glabrous. 2n = 18.

Artemisia suksdorfii is similar morphologically to A. douglasiana; it has more and smaller heads, and glabrous phyllaries. The two species hybridize where their ranges overlap.
