Viewed from a distance, Porter's sagebrush all but vanishes into the barren badlands, its silvery foliage practically invisible against the ash-gray backdrop. As if life isn't hard enough in the cold desert of central Wyoming, Porter's sagebrush grows in the harshest of habitats - the eroding clay slopes of badland formations. Very few plants can grow in these deserts within the desert, providing a special, competition-free niche for this mat-forming sagebrush.

Where is Porter's Sagebrush (Artemisia porteri) located in the wild?


Barren to sparsely vegetated badlands of ashy or tufaceous mudstones and eroding clay slopes. Occurs in cushion plant communities within more densely vegetated cold desert shrubland dominated by saltbush (Atriplex spp.) and greasewood (Sarcobatus vermiculatus). Often abundant in its local habitat. Elevation 5300-7000 ft. (Fertig 1994)


Limited to the Wind River Basin of central Wyoming in Fremont, Johnson and Natrona counties.
