    Ecological Adaptions:

    Mulesear grows on open flats, gentle slopes, and parks from the sagebrush-bluebunch wheatgrass zones through the ponderosa pine and aspen types up into the spruce-fir zones. It can grow at elevations up to 9000 feet.

    Mulesear sprouts from underground rootstalks or from the root crown following damage to above-ground portions of the plant.

    Uses and Management:

    Mulesear is poor forage for cattle, horses, deer and elk. It is poor to fair for sheep. The immature foliage is most frequently consumed. All classes of livestock and big game eat the flower heads. It is often a sign of past overuse of a site, usually by sheep. It is strongly aromatic.

    American Indians fermented roots of mulesear for 2 days in a pit heated with hot stones to develop a sweet flavored food.
