Sagebrush (Artemisia tridentata) blankets much of the state. This example is from the Dolores River Canyon.Sagebrush (Artemisia tridentata) is like skier traffic on I-70, you can't escape it. Every semi-desert or seemingly arid part of the state is covered with this low shrub that can grow to up to 10 feet tall. Not as fragrant as the herb, this plant, never-the-less, will exude a strong scent, particularly when wet. Don't let this "odeur" attract you to a midnight roll in the proverbial hay. Sagebrush can cause dermatitis in humans who are highly allergic to it.
