Prairie sagewort
Prairie sagewort (Artemisia frigida), also called fringed sage, forms low silvery mats on the driest, thinnest ground in the western Plains. It stabilizes eroding slopes, holds snow, and provides winter browse and small-mammal cover where little else grows.
Why landowners plant prairie sagewort
- Survives on sites too dry and shallow for most seeded species.
- Low woody base traps snow, adding effective moisture to the site.
- Winter browse for pronghorn, deer, and sage-associated wildlife.
- Adds structural diversity in shortgrass CP2 and CP38 plantings.
Site fit
Dry, shallow, gravelly, and eroded soils in Montana, Wyoming, Colorado, and the western Dakotas. Avoid mesic or productive sites — it is an indicator of dry, low-fertility ground and will be outcompeted elsewhere.
Establishment
Seed is extremely fine; surface-broadcast onto a firm seedbed and cultipack, never bury. Dormant seeding is the most reliable approach. Establishment is slow but plants are long-lived.
Management
It increases under heavy grazing, so abundance is a rangeland health signal. Fire kills established plants, so keep it out of frequently burned units where it is a management target.
CRP practice fit
Diversity component of western shortgrass plantings.

Frequently asked questions
No. Prairie sagewort (Artemisia frigida) is a low semi-shrub under 18 inches. Big sagebrush and silver sagebrush are much larger woody shrubs.
On dry, shallow, eroding western Plains ground at very low rates. Skip it on mesic or productive sites.
