Northern wormwood is a low-growing (to 30 cm), tap-rooted biennial or perennial. The basal leaves are 2.5–10 cm long, 2-3 times divided into mostly linear divisions, and crowded into rosettes. Leaves and stems are covered with fine, silky hairs. The inflorescence is narrow, with relatively large flower heads. The outer flowers are pistillate and fertile, disk flowers are sterile, and the achenes and receptacle are glabrous.

Ecoregions
Coast Range
Oregon's Coast Range, known for its dramatic scenery, is extremely diverse, with habitats ranging from open sandy dunes to lush forests and from tidepools to headwater streams. It follows the coastline and extends east through coastal forest to the border of the Willamette Valley and Klamath Mountains ecoregions
West Cascades
The West Cascades ecoregion extends from east of the Cascade Mountains summit to the foothills of the Willamette, Umpqua, and Rogue Valleys, and spans the entire length of the state of Oregon. It is largely dominated by conifer forests, moving into alpine parklands and dwarf shrubs at higher elevations.
