Artemisia tridentata ssp. vaseyana (Mountain big sagebrush)

Evergreen shrub with gray-green leaves typically 2-4 ft. tall though occasionally taller, flowering July to October. Prefers moderately deep, well-drained, slightly acidic to slightly alkaline soils on foothill benches, upper slopes and mountain meadows; 2,500 to 10,000 ft. elevation. Likely the most abundant of the big sagebrush subspecies. Occurs at higher elevations and in higher precipitation zones than the other subspecies. Also found on lower elevation sites with sufficient summer moisture, late-melting snow drifts, or on north facing slopes. Readily killed by wildfire; does not resprout. Extremely palatable subspecies for ungulate and sage-grouse forage; important wildlife habitat. Provides valuable cover for wildlife.
