Artemisia tridentata ssp. wyomingensis (Wyoming big sagebrush)
Evergreen shrub with gray-green leaves typically 2-3 ft. tall, flowering July to November. Adapted to well-drained loamy or occasionally rocky soils, from harsh dry sites of low valleys and plains, to benches and mid-elevation mountain slopes; 2,500 to 7,500 ft. elevation. Most drought tolerant of the big sagebrush subspecies. Range overlaps with the other two subspecies, occupying sites with shallower, more arid soils. Will not resprout after wildfire. Used heavily by big game species during winter months. Not as palatable as Mountain big sagebrush (ssp. vaseyana), but more palatable than Basin big sagebrush (ssp. tridentata). Crucial food source for sage-grouse. Provides valuable cover for birds and small mammals.
